Hi all!
I have a problem with my wireless card, the computer freezes when I enter password
for network.
I use 11.04 and chipset is atheros AR2427.
I followed the instructions in thread:
http://ubuntuforums.org/showthread.php?t=1745354
No success and I followed the instructions in thread:
http://ubuntuforums.org/showthread.php?p=10750214#post10750214
No success there either.
So how do I fix this problem as I do not seem to be able to fix it with the help from these threads?

Many thanks in advance!

Marcux

Which network do you wan to connect to? Hiding a network often makes problems and is not a security setting. You better broadcast the ESSID

I have tried both in my hidden network and in another network with broadcast on the SSID, same problem.
There is no issue with my hidden network as I got another Ububtu machine, a Debian machine and a Meego machine running in that network perfectly fine, no issues at all.

Folks, bios upgrade worked for me on my Acer Aspire 5250.
