How to use Wi-Fi channels above 11?

Question

I've seen multiple reports for this bug on Ubuntu, yet no solution. In this case, the network is recognized but I can't connect.

(No, it's not a router/driver issue.)

Solution

This might be a way to work around this:

Notably:

Put the following line in your /etc/modprobe.d/options
options cfg80211 ieee80211_regdom="EU"

Then reload the module iwl4965 or iwl3945 and channels 12 & 13 should work
again.

Are you in the US? If so, the current standard is channels 1-11 for 802.11b/g. You will not be able to use the upper level channels. See en.wikipedia.org/wiki/… for more information.

Nope, I'm not in the US.
