If your router is connected to the same channel as those used by other Wi-Fi networks in the nearby vicinity, you could experience a slow connection or one that frequently drops out. By configuring your router to use a channel that’s less crowded (or ideally not used by anyone else) then you can avoid these problems. You could just try flicking between different channels on your router until you get the best Wi-Fi experience. Alternatively, you can download this free app that does the hard work for you.
Once you’ve installed Wi-Fi Analyzer, you’re presented with a graph that shows the different Wi-Fi networks nearby in different colours and the channels they are currently using along with the strength of signal. This will give you an idea of whether your network has a strong or weak signal and whether the channel is currently set to is crowded or not. You can also view the signal strength of ach of the networks in the style of a speedometer in a car and see network details such as security levels and exactly which channel they’re using.

We also loved the fact that by pressing CH rating you get a star score out of ten and a suggestion of which channels would ensure your network is stronger.
The app won’t automatically configure your router, so you’ll need to do that yourself.
