If you use Zero Shell and want to see which wireless networks access points are visible to it the web interface does not allow you to do anything wifi based.
The SSH “push button” interface also doesn’t offer this function.
You do have to use shell!
ifconfig wlan0 up iwlist wlan0 scan | grep 'Encryption key' -A 1 -B 1 ifconfig wlan0 down
Which should return something similar to this:
root@myrouter ~> iwlist wlan0 scan | grep 'Encryption key' -A 1 -B 1 Quality=20/70 Signal level=-90 dBm Encryption key:off ESSID:"BTWiFi-with-FON" -- Quality=35/70 Signal level=-75 dBm Encryption key:on ESSID:"virginmedia8106815" -- Quality=22/70 Signal level=-88 dBm Encryption key:on ESSID:"DIRECT-76-HP OfficeJet Pro 6960" -- Quality=26/70 Signal level=-84 dBm Encryption key:off ESSID:"BTWiFi" --
Shows you the Name of the network and if the network has encryption (password) enabled.
