[Bug 275279] Re: Intel 4965 wireless can't see wifi channels 12 and 13
This is a limitation of the regulatory handling in the kernel. For intrepid the you will need to use the module option work around: options cfg80211 ieee80211_regdom= For Jaunty and later the new crda regulatory domain daemon in combination to the passive scanning support should trigger these channels automatically when a beacon is seen. Closing Won't FIx for Intrepid and Fix Released for Jaunty and later. ** Changed in: linux (Ubuntu Intrepid) Status: New => Won't Fix ** Changed in: linux (Ubuntu Intrepid) Assignee: (unassigned) => Andy Whitcroft (apw) ** Changed in: linux (Ubuntu) Status: In Progress => Fix Released -- Intel 4965 wireless can't see wifi channels 12 and 13 https://bugs.launchpad.net/bugs/275279 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 275279] Re: Intel 4965 wireless can't see wifi channels 12 and 13
I'd like to make a small point. If you are using linux-backports-modules (lbm) because you need a newer wifi driver, the module that regulates which channels you see is no longer "cfg80211" but "lbm_cw_cfg80211". Thus, the line that needs to be added to /etc/modprobe.d/options is options lbm_cw_cfg80211 ieee80211_regdom="EU" Unloading and reloading the wifi modules works like a charm, no need to reboot. By the way, is it a bug that linux-backports-modules doesn't detect the options appended in /etc/modprobe.d/options and modifies it for the modules included in that package? I mean, because some slightly differently named modules are used, I'd expect them to pick the options applied to the original ones. -- Intel 4965 wireless can't see wifi channels 12 and 13 https://bugs.launchpad.net/bugs/275279 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

...and users in Australia and New Zealand. These days, for global standards, "European" means pretty much everyone outside North America. The US tends to do its own thing and everyone else does the OTHER thing. In the case of frequencies, the US reserved many frequencies for military use that are open frequencies everywhere else. This is why North American cell phones were for years different to everyone else's cell phones.

[Bug 275279] Re: Intel 4965 wireless can't see wifi channels 12 and 13
Dave's comment above fixed my problem. I have an Acer 2483 TravelMate laptop with an Atheros wireless chipset. Before I added the "options" line above to /etc/modprobe.d/options (and re-booted), my wifi only saw 11 channels. But now it sees 13. st...@steve-laptop:~$ iwlist wlan0 channel wlan0 13 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Channel 12 : 2.467 GHz Channel 13 : 2.472 GHz Current Frequency=2.472 GHz (Channel 13) My AP is on Channel 13 and was not visible prior to this change. Now, I can connect to the same AP with no problems (D-Link DI-624S set to "auto" with respect to channels). -- Intel 4965 wireless can't see wifi channels 12 and 13 https://bugs.launchpad.net/bugs/275279 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I want to confirm this behaviour in the Intel WiFi Link 5300 present on my Thinkpad T400. Dave Nice's advice worked great, and only putting off and on again iwlagn was enough to detect my AP. -- Intel 4965 wireless can't see wifi channels 12 and 13 https://bugs.launchpad.net/bugs/275279 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Aha - looking at bug 275279 and adding this line to my /etc/modprobe.d/options options cfg80211 ieee80211_regdom="EU" "iwlist wlan0 channel" now reports seeing channels 12 and 13.
