My wireless card was working fine for some time, but after reinstallation of computer with Ubuntu, it stopped working and i keep getting this in my dmesg:

Does this mean i have issue with driver/kernel or my wifi card is broken? I tried copying latest uucode for 2230 wireless card (http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-2030-ucode-18.168.6.1.tgz) into /lib/firmware and reloading kernel module, no success. Still the same issue.


Best regards,
