Link to original launchpad discussion

Basically for a few weeks my wireless hasn't been working properly. I could see wireless networks, but not connect to them. Asked launchpad on how to help, and when I did what they said to do, it only made my problem worse, now I cant see ANY wireless networks.

Link to re-opened question. Same thing as original I just created a new question with the same stuff so new people could see it.

Can you try to connect / list the network list and post the output of grep -E 'Network|wlan|wpa' /var/log/syslog | grep "$(LANG=C date +'%b %d')"? – Lekensteyn Mar 22 '11 at 9:22

You can undo those changes, remove /etc/modprobe.d/iwl3945.conf by running:

sudo rm /etc/modprobe.d/iwl3945.conf
