Now that everyone in the world and his/her dog has a Wi-Fi router, those who live in cities or towns often suffer from overlapping Wi-Fi signals, as their neighbours' routers are all sharing a pretty tight wireless frequency range. It’s not uncommon to turn on Wi-Fi on your phone and find that there are ten or more wireless networks in close proximity.
If they happen to be transmitting on channels that are close to that used by your router you may experience a drop off in wireless performance. Wi-Fi Analyzer is a simple, but effective app that scans networks within range and shows you which channels they are using. This allows you to then find a free channel that you can switch your router to in order to avoid interference and boost wireless throughput. It will even suggest better channels that you might want to choose.
WiFi Analyzer provides an easy way to find the right wireless channel to use in order to avoid interference from your neighbours’ networks.
