Title:
13.10 Intel 6205 WPA2 enterprise wifi drops
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
This is a longstanding problem, not fixed in 13.10. I can connect to
my university's wpa2 wifi. The connection typically works initially
but becomes unusable after a few seconds or a minute or two. On rare
occassions it remains up for an hour or two. The machine is a Lenovo
X220, I have the latest BIOS (1.39), and this is a fresh install of
13.10 (xubuntu). I can connect without problem to our public unsecured
network, and I can connect to my wpa2 network at home.
