View Full Version : [ubuntu] Wireless Connection Stopped Working

October 20th, 2010, 05:12 PM

About a week ago I upgraded to Maverick from Lucid.

All networking worked fine on Lucid.

I am using an Acer Laptop with the Atheros AR928X Wireless Network Adapter.

I can connect to my home network (visible, with WPA2-Personal) fine. However, I cannot connect to my university's wireless network. The only difference I noticed is that its network is using WPA2 Entreprise with Tunneled TLS Authentication and MSCHAPv2.

I tried dmesg and I got:

wlan0: authenticate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: authenticated
wlan0: associate with 00:1a:1e:ef:f4:e1 (try 1)
wlan0: RX AssocResp frin 00:1a:1e:ef:f4:e1 (capab=0x431 status=0 aid=2)
wlan0: associated
wlan0: deauthenticated from 00:1a:1e:ef:f4:e1 by local choice (reason=1)
cfg80211: All devices are disconnected, going to restore regulatory settings
cfg80211: Calling CRDA to update world regulatory domain
cfg80211: World regulatory domain updated:
(a bunch of frequencies show up. I am copying this manually, so if needed will copy the rest)

Any ideas? Unless the driver has changed, I suspect this is not a driver issue, since it worked fine on Lucid. Is this a NetworkManager issue?

Please help! I need Linux to complete my Master's Thesis! And I can't stand Window$!

Maybe you can doublecheck there with your findings?
