WiFi Explorer review: Find problems with and optimize your wireless network | Macworld

Wifi Explorer

“Adrian Granados’s $3 WiFi Explorer (Mac App Store link) is a nifty Mac utility that allows you to gather an impressive complement of data about all the Wi-Fi networks within range of your Mac. It shows you a plethora of numerical data points, but it also graphs the signal strength of each network, and it shows which networks overlap on common channels. It supports 802.11a/b/g/n networks in both the 2.4 GHz and 5 GHz frequency spectrums, as well as 802.11ac networks on the 5 GHz band.”
