2nd When i walk with my phone to work and when i arrive looking at the
indicator network it still shows that i am connected to my home wifi.
When this happens, did you check 'nmcli d' to see if WiFi actually was
still connected? If so, this is probably a WiFi driver issue. If NM
shows WiFi disconnected, then it's probably a bug in indicator-network.
Maybe start with an indicator-network bug and we can try to isolate
where the problem really lies?

3rd I can have up to hundred + WIFI SSID to select from in the network
indicator. I suppose those are cached and not deleted when they are
not in range anymore. (link to 2nd problem)
Please open an indicator-network bug for this as well.
