Free Handheld Wi-Fi Analyzer
How would you choose the best Wi-Fi hotspot from all the people your phone lets you know are available, produce a detailed coverage map of the SOHO (Small Home/Small Office) network or determine which is the greatest channel for this? All you need is an Android mobile device and a Wi-Fi analyzer app.
Google Play for a listing of Wi-Fi analyzer apps. Wi-Fi Analyzer, put together by Kevin Yuan of farproc, heads their email list using more than 10,000,000 downloads. Among its many features are the ability to display a visible graph of all active access points in your area, their SSID names, signal strength, channel numbers, MAC addresses and the form of security encryption they will use. The app is straightforward to function although you may aren't technically inclined. Measurements may not be lab quality, but all we need to solve problems are consistent relative readings.
If you're looking to get this done together with your iPhone you might be disappointed. Recent changes towards the iOS operating system block use of private frameworks that app writers need to duplicate these functions. If you have an older iPhone that hasn't been upgraded beyond the new ios 4 there are similar apps you can use. Like a last measure, you can find applications for desktop and laptop Macs that may carry out the same job. You'll have to lug bigger equipment around. To help keep things simple, I'll give instructions depending on farproc's Wi-Fi Analyzer app. Another apps should work almost exactly the same if you read through their menus for similar features.
Make use of the 'Channel Graph' view to find a good hotspot. It is the default screen that comes up advertising media are the app. In case it is not, press recption menus soft key (it appears like an eye fixed) and select 'Channel Graph'. You may now visit a graphical display of available networks. Needless to say you'll need a strong the one that rises above the rest but if you likewise want one which doesn't demand a password, look for a '*' near the SSID. It is really an option so you may need to use it within the 'Settings' menu. When there is no obvious choice, such as the one operated by the area of economic you have, watch the screen for a time to determine which ones provide a consistent signal. Weaker ones could quit completely after a few seconds. Hopefully there will be an appropriate network, on a single from the three channels with the least amount of overlap (1, 6 and 11), around the 2.4 GHz band. You can also take a look at what are you doing on the 5 GHz band by tapping the very best left corner. For some reason there isn't any icon there if you don't touch it.
Now that you've a good idea how to use Wi-Fi Analyzer, try building a coverage map of your house or office wireless network. It may seem easier to switch to 'Signal Meter' mode. It measures only 1 signal at a time so make sure it's yours. Or even, press and contain the network name, choose 'Select AP' from the menu then select your network.
Use a printed layout of your all of your rooms then go on your travels and take readings at each one. Make sure to permit the meter to stabilize before you record a measurement. That could take 15 or even more seconds. If it keeps going up and down utilize the lowest reading for the map. Make certain all your readings range from same phone so everything is relative to the identical starting place. If you are done you'll easily see in which the troubles are. You can now take the necessary steps to repair them.
To see if it is possible to improve wireless network performance, visit the 'Channel Rating' screen. It rates every one of the available channels on the scale of a single to 10. The greater the rating, the less interference with that channel. Monitor the screen as it rates all channels in real-time, updating continuously as conditions change. Yet again, make certain it's set to your network. Press and contain the network name to improve it.
