now connecting to my WPA-802.1X with a Intel 7260 fails, see dmesg.

 From the wifi's wpa_supplicant file (actually wicd somehow accumulated 
different ones for this SSID, but the following should be it):
     proto=RSN
     key_mgmt=WPA-EAP
     pairwise=CCMP
     eap=PEAP
     phase2="auth=MSCHAPv2"

Meanwhile my WPA2-PSK at home still works.
