I took some time today to fiddle with netcfg, ifplugd, net-auto-wireless
and wpa_actiond. Your script, slightly modified, works fine in my case
Thomas, thanks. Took me a bit to figure that it needs to replace
ifplugd.action though.
Now with net-auto-wireless before ifplugd in the daemons-array the
system works fine (as long as I'm not too fast with unplugging and
replugging). I get just cable at home and wireless at university,
everything's fine, except that I still get disconnected from the
university wlan about every 30 minutes. net-auto-wireless didn't change
a thing in this regard. Here's an excerpt from everything.log, pretty
beginning with bootup. The reconnects in there are from manually running
'/etc/rc.d/net-auto-wireless restart', the thing that I tried to avoid.
I have no idea why these disconnects happen:
