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: ----- Oct 8 12:03:34 localhost kernel: [ 11.539025] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio2/input/inp ut6 Oct 8 12:03:34 localhost kernel: [ 11.739452] [drm] initialized overlay support Oct 8 12:03:34 localhost kernel: [ 11.872555] fbcon: inteldrmfb (fb0) is primary device Oct 8 12:03:34 localhost kernel: [ 11.914034] fixme: max PWM is zero.
