For a long time now I have had this problem with iwm and wlan0. Whenever I move between work and home it won't reconnect automatically and I have
to do wlan0 scan manually for it to pick up the different network.

I suffer from the dreaded "reason=0" when I move inside my house:

        > scan
        OK
        <3>CTRL-EVENT-SCAN-RESULTS
<3>Trying to associate with 6c:3b:6b:3d:a2:e9 (SSID='Palombia' freq=2452 MHz)
        <3>CTRL-EVENT-DISCONNECTED bssid=6c:3b:6b:3d:a2:e9 reason=0
        <3>CTRL-EVENT-SCAN-RESULTS
<3>Trying to associate with 6c:3b:6b:ab:ce:d4 (SSID='Palombia' freq=2412 MHz)
        <3>Associated with 6c:3b:6b:ab:ce:d4

a2:e9 is the loudest AP here in my office, but my I have been in the
other end of the house iwn consistently fails to associate with it and
and keeps picking the weaker AP in the far end.

Eventually (hours!) it disconnects from the weaker ap, also with
"reason=0" and gets it right:

        <3>WPA: Group rekeying completed with 6c:3b:6b:ab:ce:d4 [GTK=CCMP]
        <3>CTRL-EVENT-DISCONNECTED bssid=6c:3b:6b:ab:ce:d4 reason=0
        <3>CTRL-EVENT-SCAN-RESULTS
<3>Trying to associate with 6c:3b:6b:3d:a2:e9 (SSID='Palombia' freq=2452 MHz)
        <3>Associated with 6c:3b:6b:3d:a2:e9
<3>WPA: Key negotiation completed with 6c:3b:6b:3d:a2:e9 [PTK=CCMP GTK=CCMP] <3>CTRL-EVENT-CONNECTED - Connection to 6c:3b:6b:3d:a2:e9 completed [id=3 id_str=]
        <3>WPA: Group rekeying completed with 6c:3b:6b:3d:a2:e9 [GTK=CCMP]

And yes, working roaming would be nice too...

I have the problem that when roaming networks become disabled

        $ wpa_cli
        Selected interface 'wlan0'

        Interactive mode

        > list_networks
        network id / ssid / bssid / flags
        0       network1        any     [CURRENT]
        1       network2 any    [DISABLED]
        2       network3 any    [DISABLED]
        3       network4 any    [DISABLED]
        4       network5 any    [DISABLED]
        Selected interface 'wlan0'


I address this by doing network_enable x in wpa_cli and it all comes
back. I asked Adrian about this in the past, but it needs some debugging
to pin down.


Is this iwm(4) as well in your case or another card?
