How to choose
To inspect nearby Wi-Fi networks and channel use, see inSSIDer. A wireless analyzer helps investigate coverage and interference; check compatibility with your adapter and the functions included in the selected edition.
Compare readings from several locations, including the place where the connection is poor. Walls, distance and neighboring networks can affect results. Signal strength is different from internet speed, so also check the connection to the router and your provider.
