I experienced this (as per my earlier comment). It drove me nuts, so I did a little digging.
Wired connections were OK if I used "wpa_supplicant" via the terminal and added "fast_reauth=0" to my configuration file. Wireless worked if I used the Wicd network manager, but Wicd doesn't support WPA over wired connections. So I've arrived at a compromise between setting up my "/etc/network/intefaces" file as follows: "# Ethernet interface auto eth0 iface eth0 inet dhcp wpa-driver wired wpa-conf /etc/wpa_supplicant/wired.conf" That handles wired connections. Wicd handles wireless flawlessly. I hope this helps somebody, but of course your mileage may very. -- Eduroam randomly disconnects https://bugs.launchpad.net/bugs/429370 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
