Hi!

I am back home now and so are my problems, while my wireless configuration worked flawlessly at my parents' WLAN:

I could always reconnect by running a simple "sudo ifup eth1" after a "sudo ifdown eth1" at my parents' WLAN (even though the WLAN LED flickered for a while), but back home my interface "eth1" gets lost after "sudo ifdown eth1".

Here is my current "wpa_supplicant.conf" (unchanged, except that I removed the "eapol_version" and "ap_scan" options):

   ctrl_interface=/var/run/wpa_supplicant

   network={
       ssid="some_ssid"
       scan_ssid=0
       proto=RSN
       key_mgmt=WPA-PSK
       pairwise=CCMP
       group=TKIP CCMP
       psk="some_psk"
   }

And here is a sample session with these settings (at my home):
