WiFi Explorer is a wireless network scanner utility that allows you to identify channel conflicts, overlapping and other configuration issues that may be affecting the connectivity or performance of wireless networks at your home, office or other sites.
WiFi Explorer's main features are:
Supports 802.11a, b, g and n networks in the 2.4 and 5 GHz bands, as well as 802.11ac in the 5 GHz band.
Supports 20, 40, 80 and 160 MHz channel widths.
Monitors and graphs channel allocation, received signal strength (RSSI), background noise, and signal-to-noise ratio (SNR).
You can use WiFi Explorer to identify network configuration problems, such as incorrect mode, incorrect channel or channel width, and incorrect security or encryption settings, as well as to diagnose poor signal quality due to:
Interference caused by channel conflict and signal overlapping from competing or adjacent networks.
Weak signal strength or high background noise levels.
