AppId is over the quota

You likely have many wireless devices that need charging including mobile phones, laptops, pads, or tablets. Thus you probably also have a clutter of wires connected to chargers somewhere in your home. This set-up has probably always felt like a necessary part of the new world of technology.

Enter wireless chargers, including stylish pads and mats that reduce the clutter down to just one wire. And these wireless charging pads and mats are so simple that all you have to do is place your device on top and wait for the beep that sounds to say your device is charging. And on many models a light comes on when your device is charged - a convenience you don't have with wired chargers.

Most wireless chargers can charge up to three devices at one time using a simple technology called inductive charging. Basically the charging pad or mat creates an electromagnetic field that travels a defined path to your device through the use of a small attachment you put in the battery compartment of the device. The charging pad or mat can create three of these transformers at once, allowing it to charge three devices.

The technology behind these wireless chargers is so simple that these products have been perfected quickly. You can expect that your pad will:

- Be highly convenient, always on without wasting electricity. This way you do not even have to flip a switch to use the charger - just place your phone or other device on the pad.

- Be easily portable - in fact there are travel versions of wireless chargers that roll up
and fit in small spaces, but even the standard chargers can easily be packed up.

- Be built to last since they are so simple and durable. Look for a generous warranty.

- Allow you to avoid common problems people face with wired chargers including mistakenly not fully plugging them or damaging the phone.

In the near future wireless chargers may crop up in hotels and other places where you travel, so if your phone, pad, or tablet is set up correctly you may be able to benefit from a new convenience that will allow you to leave all those wired chargers at home. We may also see this technology perfected to the point that you don' t need any attachments on your phoned

Charging pads and mats are simple and elegant, and of course very functional and handy!

Easy Setup Wireless Repeaters

AppId is over the quota

Some of us don't have a problem setting up wireless repeaters. Then again some of us probably wouldn't have a problem coding their own operating system so who knows. Some of us don't have time to keep up on the latest technology and we appreciate when things are being made easy. There's a lot to be said for a wireless network which just works and sadly this is too rare. Something always goes wrong and a wireless repeater is supposed to make things easier - not harder. So rather than having to deal with security settings and who knows what else I like having it easy and there's a few way you can find an easy wireless repeater which won't cause a headache.

The easiest way to get an easy setup is with Wifi protected setup (WPS). The setup process can be as simple as pushing a button on your router and pushing another on the wireless repeater itself. The router looks for another device which has currently had the button pressed and there's no complicated setups or settings. It takes your original settings for the first network and uses the same thing. You don't even need to enter your wireless password because pushing the WPS button requires physical access which counts as some pretty good security against people stealing your internet.

The problem with WPS is twofold. Firstly there is a fairly large security hole with malicious users practically brute forcing the WPS beacons. This can be sorted by disabling WPS when you're done with it or by patching your firmware to a point where it automatically prevents a brute force on the WPS.

But the second problem is incompatibility. Sometimes frequencies or security encryption doesn't line up and other times you might not even have WPS on your router in the first place. If someone gets a repeater or range extender based on the fact it is easy to install then they're not going to be pleased when it doesn't work straight out of the box.

So it's impossible to make WPS compatible with a router which doesn't have WPS. But there is still a way to get easy to use wireless repeaters and that lies in the setup procedure itself. Now I have a golden rule. If my mother can set one up I consider it easy.

My five year old Linksys repeater (called a range expander back then) had a pretty buggy setup. You had to install software from a CD which didn't even have an autorun and it wasn't clear how you were supposed to do things or what to do when things went wrong. At the time originally I got it working with a lot (and I mean a lot) of trial and error.

The setup was tricky, required a working knowledge of wireless networks and at least a basic understanding of what could be going wrong and why. Because the setup process itself was sure as hell not going to tell you.

I have since upgraded (thankfully) to a better (newer) model which not only supports the latest routers but has an easy to use setup which actually runs directly from the router itself. Rather than having to connect a cable (which didn't even come with the original Linksys repeater) you just connect to the new wireless network the repeater makes. You go to a website (an internal IP) hosted within the repeater and choose the network you want to repeat. The setup is easy to follow, does mostly everything for you and if something doesn't work it suggests possible reasons why starting with the most likely. This I would call an easy setup.

So to find the wireless repeaters which are going to be easy to setup look for three things. Firstly compatibility with your router. You're going to get nowhere if you have a decade old repeater which can't handle the same frequency or encryption as your router is using. Secondly look for WPS if your router has a WPS button on the side but make sure you log in to the router afterwards and disable WPS afterwards unless you're positive the model is patched against brute forcing (or you really, really trust your neighbors).

Lastly, look for something updated. Not only will this mean you're more likely to find the compatibility you need but you're less likely to run into some outdated setup process. A lot of the newer range extenders and repeaters from manufacturers like Netgear, Amped and Cisco have really improved their setups to suit people who don't want the bother of fighting with their wireless network and the setup would pass my 'can my mother do it' test.

Don't let WiFi networks get you down or setting up wireless repeaters as tricky as it can be. Have a read at our guide on http://wifirepeaters.net/easy-setup-range-extenders/ for a look at wireless repeaters which are easy to use.

Go Wireless With My Bluetooth Places

AppId is over the quota

When we think about electronics, what comes into mind are a bunch of wires that connects from one device to another. Headphones connect to audio players, keyboards to computers, headsets to PCs, and so on. All these connections usually end up as a jumbled, tangled mess. These days however, electronic devices can be connected to one another without the need for wires and cables. This is made possible by Bluetooth technology. Once connected, it will enable devices to communicate with one another through my Bluetooth places.

First of all, what is Bluetooth? The term was coined from the 10th century Danish King, Harald Bluetooth, who had been instrumental in uniting Scandinavian Europe when it was torn apart by wars and feuds between clans. Bluetooth technology is a short-range wireless form of connection that allows electronic devices to communicate with each other. This has been around for some time, but has only been tapped into during the recent decades.

How does this technology work? Simply put, its goal is to establish a "language" between electronic devices. A standardized, wireless protocol is being used so that these gadgets can connect and communicate with each other. For the devices to be able to communicate, each must be Bluetooth capable. For example, if you want to establish wireless communication between your phone and your PC, you can just install the software and you can click on my Bluetooth places to start using it.

However, most electronic gadgets will automatically install and search for other contraptions to pair up with. This is one of the conveniences provided by Bluetooth technology. Once the devices are paired up, you can just go to my Bluetooth places so they can begin communicating. The beauty of this is that the technology does not just establish a one-on-one connection between gadgets but can pair up with several at one time, so that when transferring files, for example, you can send this to a number of devices all at once.

There are a lot of devices nowadays that are enabled with this technology, which brings the surrounding clutter of wires around us to a minimum, despite the number of electronic gadgets that might be populating our area. If you want to know which contraptions today are Bluetooth capable, take a look at electronics stores or browse around the web and discover them for yourself. Who knows, you might find something that you thought would never function without wires, and yet, is currently wireless in form.

Whatever kind of Bluetooth-enabled electronic tool you might want to possess these days, just keep in mind that technology is constantly (and rapidly) evolving. This is to save yourself from frequently discarding what you bought just because technological advances have already rendered your gadget as obsolete. Make sure that the device you have can still function even with the upgrades that might come its way in order to save the gadget and allow its value to be carried on into the future.

Visit http://mybluetoothplaces.org/ and take a look at the Bluetooth headsets and accessories available there for you. Enjoy!

Wireless Internet Card: What Is It?

AppId is over the quota

A wireless Internet card is one of the most important tools for any individual owning a laptop. This device is within the computer. It allows the user to connect to various hot spots wherever they go. At home, you may have your system setup to automatically log into your wireless connection. You do not think about it. It just automatically logs in and begins working for you. When you travel with your computer, though, you will need to have a way to link into the various wireless connections that become available. If you cannot do this, there is no way for you to get online to the Internet.

Most of the time, computers come with these cards built into them. You do not have to invest any time or attention into using them since they are preinstalled. It can be interesting to understand how they work, though. Most personal computers will have the card in place to pick up a signal that becomes available. The device is very small, usually no larger than the size of a credit card. It is tucked away inside the laptop to keep it protected.

The wireless Internet card works as an adapter for your computer. Like other devices that you put into your computer to change the way you use the computer, these devices work to enable your current laptop to do other functions. These cards are also known as Local Area Network or LAN cards. Other types of adapters are available that can also work well to adjust the way your computer works. For example, some devices work to enable teleconferencing on a computer. Others will work to change or improve the sound system. Some allow you to download photos from your camera onto the computer. The more ways you can use your computer to work for you the better. These devices help you to do that.

There are variations in these cards, though. The card must be specific to the actual type of device you own. For example, the cards for a PDA are going to be different from those in a laptop. Laptop and desktop computers are also significantly different. You will need to purchase one that is the right specification for your system if you hope to use it properly. The good news is that most of the time, these are already built into the computer so there's no need to install one on your own. However, if you need to make changes to it, you can do so. Most of the time, this investment is not an expensive one. You may be able to install it yourself if you have a bit of experience working with computers. They are often put into a slot on the side of a computer for external types.

As you consider the ways that you can adapt the way you use your computer, consider your wireless Internet card. If it is not working properly, it may be time to upgrade. If you are investing in a new modification for your computer remember to look for the proper adapter for it. Having this type of tool in place can greatly improve the way you use your computer and the flexibility you have overall. Most of the time, it takes simple changes to the way your system is set up to give you the freedom to take it anywhere and to log into various systems for connectivity. With this device, you really can tap into the Internet wherever you go and where a hotspot exists. That can make a significant change in the way that you use your system. What could you accomplish with this type of update?

Wireless Troubleshooting

AppId is over the quota

Whenever troubleshooting Wireless Connectivity or a customer is complaining about dropped connection issues always remember these items...

1. Change the Channel (Auto is not your friend when troubleshooting)

For 802.11n routers we like to use channels 1,3,6,9This one is very important, but often overlooked, one of the first things that should be done if a customer is complaining about dropped signal or intermittent wireless connectivity will be to set a static channel.

2. If connecting 3rd party devices that are not computers, use a WPA key that does not include special characters to ensure compatibility. While all devices should be able to figure out those fun &(*&*$#@( characters sometimes they cannot so go with Alpha Numeric and Upper Case / Lower Case for max interoperability.

3. If you want to achieve 802.11n speeds you NEED to use WPA2-AES also known as WPA2 Personal on our new routers. WPA2 and WPA2 Personal are the only security types that can support 802.11n speeds

Many customers that call us and complain about Slow Internet call because they have an old security being used on their network that is actually slowing down their Broadband. Quick and simple math says if a customer is paying for 20 megabits of bandwidth, but they are using WEP they are not going to be happy. Remember always try to use WPA2 Personal with 802.11n routers, if they have devices that are older recommend an upgrade to their adapter if you can (LTR, LTR, LTR) and if not inform them about the drawbacks of using older security.
Also by default remember most routers are setup to do WPA/WPA2 mixed mode to ensure maximum compatibility. While compatibility is nice it is not a friend of speed. Don't be afraid to change to a pure WPA2 configuration if the customer is using newer equipment in their network.

4. If a customer is complaining about intermittent connection or has one device that is having problems connecting to the network... Make sure that the customer has the latest drivers for their adapter. Agents love to blame the router and update the firmware... But the adapter software is equally important, and often overlooked (Remember Atheros?? Not our issue, but caused by BAD DRIVERS for the adapter ).

Also since on our newest routers you cannot manually update the firmware anymore it is even more important to properly troubleshoot the issue and focus on all possible areas of concern.

5. Make sure that the router is in the open not buried under a desk or under a pile of laundry in your basement. Wireless uses radio waves to communicate, and your router is like the radio antenna. So the higher up your antenna is the better your signal and range will be. Also a key thing to remember here most customers will put their nice new router right near an exterior wall in their home. So half of their super powerful signal is being lost out in their yard or even worse to their neighbor's house. It is always good to suggest that a customer place the router as close to the center of their home as possible. This is not going to be possible, but as a technician it is good to educate the customer about the importance of placement.

Getting the Best Wireless Speaker for Your House

AppId is over the quota

I am going to offer some guidance to help you choose a pair of wireless speakers from the large number of available models.

Wireless speakers are a great choice for adding speakers in additional rooms of your house without adding wiring. In addition, these speakers are ideal for adding surround sound to your TV without running lots of speaker cable around the room.

Wireless speakers are more difficult to pick than regular speakers since they incorporate an amplifier and a wireless receiver. Different models differ in quality of each of these components.

Speaker wattage is one of the first parameters. The larger the speaker wattage typically the higher the speaker sound pressure level can be. The maximum speaker wattage depends on both how much power the speaker elements can handle as well as the power rating of the built-in amplifier. Don't be fooled by maximum wattage ratings which are often exaggerated by manufacturers and rather take a look at the RMS wattage rating.

However, keep in mind that music signals have large spikes in output power so be sure there is enough headroom in the speaker power rating to eliminate audio compression at short audio bursts.

The frequency response of the speaker shows the frequency range the speaker can reproduce. However, different manufacturers use different conventions when specifying the frequency response. Ideally, you should get a copy of the speaker frequency response curve of each model for comparison.

Audio amplifiers will have audio distortion which varies depending on the output power at which the speaker is driven. The distortion is often called "THD" or "total harmonic distortion". Make sure you compare the output power at which the harmonic distortion is specified. Ideally you will find harmonic distortion figures for different power figures Once the audio amplifier is driven to its maximum power, audio distortion will increase dramatically due to clipping of the audio signal. Speaker audio distortion will also depend on the quality of the transducers

Speakers with larger power rating usually have digital amplifiers which offer larger power efficiency than traditional power amplifiers. Picking a model with a higher-efficiency amp is usually lighter since it does not require heavy cooling fans and saves you money on electricity. However, some digital amp models have fairly high audio distortion due to nonlinearities of the internal switching stage. Thus, pay close attention to the harmonic distortion figure.

Wireless speakers with multiple transducers will need some sort of crossover. This crossover can be implemented with passive elements. Alternatively, some models will have separate amplifiers for each transducer. In this case the gain of each amplifier can usually be adjusted separately.

The receiver which picks up the wireless audio either from a transmitter or from a wireless network or Bluetooth signal also has a major influence on sound quality. For best sound quality, you may want to avoid 900 MHz analog wireless transmission which inherently has a low signal-to-noise ratio and instead pick a receiver which uses a digital audio signal.

Digital wireless speakers will use uncompressed audio for best quality or compressed audio such as Bluetooth speakers. Bluetooth wireless speakers do not require a dedicated transmitter but usually only one speaker can pick up the audio from one transmitter. Other types of wireless speaker transmitters can send the audio wireless to several speakers throughout the home.

Nowadays the internet is the biggest repository of information and knowledge and every laptop user requires having a wireless Internet connection to his computer. It helps you remain connected via the web even while traveling. Although there are numerous Internet service providers who offer wireless internet connections but no one can be claimed free from any signal or network related issues. In such a scenario you can reap benefits if you have basic knowledge about the wireless related issues that might take place with your All-in-One 200t PCs.

Below mentioned are causes behind issues noticed frequently with wireless Internet and their respective resolution:

Router location

Location of the wireless router is one of the leading causes of wireless internet problem on your All-in-One 200t computer. The ideal location of a router is on the wall where it is most exposed to wireless signals. A router placed on the floor is considered a faulty location that needs to be changed so that your computer gets the appropriate signals and help you experience faster internet speed without any interruptions.

Weak signals due to distance between router and computer

Distance between the router and the system hinders signal flow. If the system is placed away from the router then it fails to receive appropriate signals that affect the quality of browsing. This results in frequent interruptions. This can be resolved by installing a repeater in between the computer and the router. This would enhance the quality of the signal to a great extent.

Disturbing noises

Sometimes the user gets to hear noise which again takes a toll on the smoothness of wireless connectivity. You can switch your router to another channel provided with the administrative interface of the router. In majority of the cases it proves to be useful in reducing the noise in the line and improving the wireless connectivity on your All-in-One 200t.

External interferences

If your router is installed in a WI-Fi rich region then it is expected that you will face less interference. Interference can occur even if too many networks are operating on the same frequency. Thus it is recommended to switch the router channels to find out the correct frequency. This too can work wonders in improving the speed and performance of wireless Internet on your All-in-One 200t series computers.

Apart from the above-mentioned issues you may face numerous other problems related to the wireless Internet on your system. If things do not improve after using these tips then consulting a computer support service provider is the best option.

How Do Wireless HiFi Headphones Actually Work?

AppId is over the quota

Enjoying music can lighten up almost anything you do. However, when you're for example cleaning your place or cooking in your kitchen, you actually can't always be close to the audio-player or play your music really loud considering that your family or neighbors might be bothered by it.

Using regular HiFi headphones in order to enjoy your music might not always be the best thing, either. The actual cables from the phones may be way too short; or, maybe if they are really long, they might get stuck in your things, or perhaps even your arms and legs e.g. if you're working out while listening to music. For those different kinds of scenarios, the best thing to use really are cord-less headphones.

But what actually are cordless Headphones and how do they work?

Wireless earphones have got two key-components: the base as well as the battery-powered headset which you wear on your head.The base transmitter is the component that you will connect to the music source, which is e.g. your portable CD player. It then transmits signals that your headphones will be able to pick up so they can provide music to your ears.

Infrared v. Wireless Bluetooth headsets:

The base/transmitter device can transmit data to your headsets by means of two different ways: infrared or via Bluetooth. Infra-red functions just like a handheld remote control. The actual base transmitter will need to have a clear line of "sight" towards your headset-device; if not, the audio transmission might easily get interrupted. Hence, in case you can't actually see the base sender unit, you likewise may not hear anything.

Furthermore, depending on the earphones you get, you possibly will not get any kind of signal from your sender/base in cases where you try to operate your headphones more than 7 feet away from the sender, even if you're right in front of the transmitter. So, when you have infra-red wireless headphones don't move too far away, do not go behind the transmitter unit, or perhaps to the next room in your home.

But in case you live in a studio-style house or maybe intend to simply make use of your headphones while sitting straight in front of the television to view films or play video games, then infrared Hi-Fi earphones come in really conveniently.

Wireless Bluetooth on the contrary, works like your cordless home-phone. The actual sender unit transmits a radio signal to the wire-free headphones. You simply have to set it to the appropriate channel or buy one that can automatically do this for you. Don't be concerned, this won't impede any regular broadcasting via radio channels. This kind of transmitter allows you to tune in to music as far as maybe even 90 meters away it. You can freely walk into a different room in your home without any interruption of the music. Furthermore, if your player is Bluetooth compatible, you can connect your headset directly to your music source without having the need for any transmitter.

The only real complications with Bluetooth headphones arise when someone else is using the exact same frequency you're using; in that case either one of you will need to change the channels or you may very well pick up the other person's music blended with your very own. Additionally, Bluetooth wire-less headphones will almost always be more expensive than infrared wireless earphones.

When you shop for wire less headsets, be sure you're getting the types you want. Typically, every time retailers refer to, "wireless headphones" they actually mean infra-red wireless headphones. On the other hand, every time they mention, "cordless headphones", they actually mean wireless Bluetooth phones.

** HiFi headphones nowadays come equipped with plenty of nice high-tech features. For example, check out the noise cancelling audio Technica ATH-ANC7 headphones or the latest Sennheiser model, the Sennheiser RS180. **

Aside from this, Netgear N900 also features a Guest Network Access that allows your visitors to go online without giving them the network password and they will not be able to access your computer, printers, and other home networks devices even if they are using your home network connection. The Netgear N900 also provides double firewall protection, the SPI and NAT Firewall, and prevents Denial-of-Service (DoS) attack.

With its sleek design and a transparent stand, the only thing you can ask for Netgear WNDR4500 is a reduction in dimension, and they would have possibly perfected the convenience they want to provide. With the price from $179.99, Netgear WNDR4500 is at the finest end for home networking, but you can be assured that it gives the best wireless performance worthy of your money.

Are Wireless Speakers Dependable In Real-World Conditions?

I will investigate how modern audio transmission technologies which are used in today's wireless speakers and wireless headphones work in real-world environments with a large amount of interference from other wireless devices.

The most popular frequency bands which are used by cordless gadgets are the 900 MHz, 2.4 GHz and 5.8 GHz frequency band. Mostly the 900 MHz and 2.4 GHz frequency bands have started to become clogged by the ever increasing number of gadgets such as wireless networks (WLANs), cordless phones etc.

The least expensive transmitters typically transmit at 900 MHz. They operate similar to FM radios. Since the FM signal has a small bandwidth and thus only occupies a small fraction of the available frequency space, interference can be avoided by changing to another channel. Digital audio transmission is usually employed by more modern audio products. Digital transmitters usually work at 2.4 GHz or 5.8 GHz. The signal bandwidth is higher than 900 MHz transmitters and thus competition in these frequency bands is high.

Frequency hopping devices, however, will still cause problems since they will disrupt even transmitters using transmit channels. Real-time audio has fairly strict requirements regarding reliability and low latency. In order to offer these, other mechanisms are required.

An often used method is forward error correction in which the transmitter sends additional data along with the audio. From this additional information, the receiver can recover the original data even if the signal was corrupted to a certain extent. FEC is unidirectional. The receiver does not send back any information to the transmitter. Thus it is often used for products like radio receivers where the number of receivers is large.

Another method uses receivers which transmit data packets back to the transmitter. The data packets include a checksum from which each receiver can determine if a packet was received correctly and acknowledge proper receipt to the transmitter. Since lost packets will have to be resent, the transmitter and receivers need to store data packets in a buffer. This buffer causes an audio delay which depends on the buffer size with a larger buffer increasing the robustness of the transmission. A large latency can be a problem for certain applications however. Especially if video is present, the audio should be in sync with the video. Also, in surround sound applications where some speakers are wireless, the wireless speakers should be in sync with the corded speakers. Systems which incorporate this mechanism, however, are limited to transmitting to a small number of receivers and the receivers consume more power.

To avoid crowded frequency channels, some transmitters monitor clear channels and can switch to a clean channel as soon as the current channel becomes occupied by another transmitter. This method is also known as adaptive frequency hopping.

Top 5 Tips to Secure a Wireless Network

AppId is over the quota

Wireless networks are becoming popular today and there are people, especially home users, who are switching from wired connection to wireless connection. For those who are using wireless network, it is possible for any outsider to connect into your network without you realizing it if proper wireless security practice is not applied. As a result, it is important to know how to secure a wireless network.

1. Create a strong router administrator password - If a wireless router does not have a strong password and someone able to crack the password from the outside, the network security can be compromised. By letting the unauthorized outsider to have the authority to access the router administration settings, he can do so many things up to even take control of the entire network. As a result, it is not safe to use a weak password especially the default administrator credentials.

2. Change the SSID name - SSID name is the name of a wireless network. When connecting to any wireless network, the operating system will load the entire list of SSID names which are within the range of the person who connects. It is not advisable to use names such as street address, family name, and car registration number. In other words, any names that the attacker can guess where the SSID name comes from should be avoided. A good SSID name is important as it will make outsiders not able to tell where the wireless networks are from.

3. Enable network encryption - Every piece of data transferred around the network should be encrypted where it can be configured in the router settings. If the network is not encrypted, there is a possibility that someone will attempt a 'Man in the Middle' attack in the network. It is recommended to use Wireless Protect Access encryption or Wireless Protect Access II encryption.

4. Filter MAC address - Every electronic device comes with a unique MAC address. Filtering MAC address can ensure that only the specific device that the owner of a wireless network recognized is allowed to connect into the network.

5. Reduce wireless signal strength - There is no reason for wireless signal strength to be super strong unless the network is deployed in a mansion. Therefore it is advisable not to be so generous by offering free wireless network connection to all the people who do not live in your house. Routers today can come with very powerful signal strength and if the wireless network signal is just for a studio apartment size, he can reduce the strength by changing the mode from 802.11g to 802.11b.
