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):
