Hi Gregor,
When I boot my laptop up, it connects to eduroam just fine.
However, when I move around the building, it does not associate
with any other AP.
I can't even make it associate if I manually run:
sh /etc/netstart
While running wpa_cli(8) in another tmux(1) window, I see a constant
stream of:
<3>CTRL-EVENT-DISCONNECTED bssid=12:34:56:ab:cd:ef reason=3
locally_generated=1
<3>CTRL-EVENT-SUBNET-STATUS-UPDATE status=0
I don't think this is related to wpa_supplicant(8) but mentioning
it here just in case.
In order to be able to associate with any other IP, I have to run:
ifconfig urtwn0 -nwid
Only then does the laptop reconnect.
I thought that I'll be able to simply use:
ifconfig urtwn0 -joinlist
followed by:
sh /etc/netstart
but, after I run the '-joinlist' option, I see this in ifconfig(8)
output:
ieee80211: nwid eduroam chan 1 bssid 12:34:56:ab:cd:ef -76dBm wpaprotos
wpa2 wpaakms 802.1x wpaciphers ccmp wpagroupcipher ccmp
This seemed a bit strange since I don't use 'nwid' anywhere in my
hostname.if file - only 'join' - but I guess this is how 'join'
works "under the hood"(?).
To sum it up, unfortunately, the diff doesn't work for me.
Regards,
Raf
