iwlist scan shows non-existent hotspot

Hi, GNUser!

I'm surrounded by a lot of Wifi networks. I've chosen one of them with the weak signal under -90dB, and made:

--- Code: ---tc@box:/tmp$ APN="<SSID of distant Wifi network>"
tc@box:/tmp$ while true; do sudo iwlist wlan0 scan  | grep -A 6 "$APN" | grep "Last beacon" ; [ $? = 1 ] && echo none ; done
                    Extra: Last beacon: 19547ms ago
                    Extra: Last beacon: 22734ms ago
                    Extra: Last beacon: 25917ms ago
                    Extra: Last beacon: 29104ms ago
none
                    Extra: Last beacon: 361ms ago
                    Extra: Last beacon: 3547ms ago
                    Extra: Last beacon: 6741ms ago
                    Extra: Last beacon: 9927ms ago
                    Extra: Last beacon: 13117ms ago
                    Extra: Last beacon: 16301ms ago
                    Extra: Last beacon: 19487ms ago
                    Extra: Last beacon: 22674ms ago
                    Extra: Last beacon: 25861ms ago
                    Extra: Last beacon: 29047ms ago
none
none

--- End code ---

In my understanding this means, that lost AP stay in the cache for 30 seconds and only then is thrown away.

recently I re-looked at wicd.

Altho its a GUI and might not suit GNUser, I can confirm its quite good at detecting real networks, not past networks. Might be worth a shot?

and purely selfishly.....I like its ability to swap between wired and wireless if you name your interfaces, wlan0 and eth0.....and hide WL router names you do not want to connect to, ie your neighbours
