WiFi Overview 360 is an universal information tool for wifi networks (inclusive widgets).
With this tool you can manage and optimize your used wireless network and and with one look you'll get detailed information of the WLANs (WLAN name (SSID), signal strength, channelnumber, encryptionin - open or not) in your environment.
The tab "Ch check" (channel checker) and "Ch. radar" (channel radar) are powerful tool to optimize your own wlan network. For best performance your network must use a channel or frequency range where are no other wireless networks or little as possible. WiFi Overview 360 gives you the best choice for the channel.
The "Pro" version contains no ad, have more widgets, have a powerful "WiFi Sniffer", can set "Quick connect shortcuts", can set WLAN priority and is a little recognition for my work.
