PRO/Wireless 3945ABG problem in Ubuntu 8.10

[seriousstorm85]

I have upgraded my Ubuntu 8.04 to 8.10 via my wireless network connection.

Everything seemed fine however in 8.10, I could not see my Wirless Router in the list of others.

I then looked for the model of the wirless card and the driver it uses.

The model is PRO/Wireless 3945ABG [Golan] Network Connection and it uses iwl3945

I have looked at several posts and could find the solution. So I decided to format my ubuntu partition and install 8.10 fresh incase something upgrade broke it.

With the freshly installed Ubuntu 8.10 I still have the same problem. This problem did not happen to me in 8.04 or 7.10.

The only thing I have changed in this fresh install is that I have changed is the iwl3495 file in etc/modprobe.d using these instructions

1.sudo su

2.echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > /etc/modprobe.d/iwl3945


3.reboot

Still no change, I can't see my wireless router

First. log on to your wireless router and try to change the channel to something less than 10.

next add this to

sudo echo options cfg80211 ieee80211_regdom=EU >> /etc/modprobe.d/options

and reboot and give it try.
