SOLVED: Intel Wifi not working after Ubuntu 8.10 upgrade?
 
So,

you live outside the US, you upgraded to Ubuntu 8.10 (Intrepid) and your Intel wireless card stopped working? You checked your modules & logs and found nothing wrong?

Well the cause could well be, according to the official release notes http://www.ubuntu.com/getubuntu/rele...20Intel%203945, that your router is listening to channel 12 or 13 but Ubuntu blocks these channels by default.

Run 'iwlist wlan0 chan' to see if 12 or 13 is listed.

If not, add this line to /etc/modprobe.d/options & reboot:

Code:

options cfg80211 ieee80211_regdom=EU
It helped me. Good luck.

Yeah that caught me out too. certainly one worth remembering in case you get caught out after a new install. I think this has been fixed in subsequent updates, but if you can't get those updates in the first place.
