Solving Wi-Fi Coverage Problems

Glenn Fleishman:

With a combination of graphic visualizations, lists of information, and the capability to drill down into super-technical details, WiFi Explorer has become my top recommendation for anyone trying to sort out a local Wi-Fi environment.


WiFi Explorer helps tremendously with understanding interference from adjacent networks by providing both comprehensive details and graphical insight. It also lets you see at a glance precisely how your network is configured. Apple doesn’t offer that in AirPort Utility, which shows connections and base station names, but requires you to hover over each base station to see channel assignments and other details.


The Channels view is remarkable. It shows how different base stations are occupying swaths of frequencies. In 2.4 GHz, you can see where networks overlap. Channels 1, 6, and 11 are considered non-overlapping — the central frequency for each channel is offset by 25 MHz, or more than a full channel.
