I did some "hacking" (well, more like bypassing) and set my router location to "JAPAN", please see this picture:

This allowed me to set my network to channel 14 in the Advanced Wireless Settings.

However, when I set my channel to 14 in the router, no device in my home can detect it.

Even inSSIDer 2.0 cannot detect my network on channel 14.

I think the source of the problem is in the Drivers, I probably have the European/US version of the drivers.

My WiFi card is an Atheros AR5B97 Wireless Adapter, and the current drivers I have are from Qualcomm.

How can I enable "searching" in channel 14?

Does anyone know where I can download the Japanese drivers (if any available?)

I just cannot find them. I tried advanced settings, and looking for anything channel related but without result:

Are you in Japan? Or do you want advice on how to cause interference with other devices using 2.4GHz? –  sawdust Mar 18 '13 at 0:49
    
12 and 13 is allowed here, 14 not really, but I don't think it's going to interfere more than all other networks with my network. –  user144773 Mar 18 '13 at 2:04

"I don't think it's going to interfere more than all other networks with my network." -- I was not referring to WiFi networks. If chnl 14 is not allocated for 802.11 in your country, then it's probably allocated for other protocols that also use 2.4GHz, such as 802.15.4 and cordless phones. See also Electromagnetic_interference_at_2.4_GHz, and note comment about ZigBee. –  sawdust Mar 18 '13 at 7:13

It's likely that your Atheros card is just hardware limited to be unable to access channel 14. From what I remember channel 14 is Japan only and limited to 802.11b.

If you're having co-channel interference from neighbors you might just want to upgrade to 802.11n(or hold out a little longer for 802.11ac) which will allow you more room to breathe.

ah 802.11b only, that sums it up pretty much. –  user144773 Mar 18 '13 at 11:28

The following answer is assuming that you are in the us, I do not know if you are in america, or if you live some where else, if you are not ignore this answer.

U.S. hardware to my knowledge is setup in such a way that prevent you from doing this. As I understand it the drivers are designed to work on channels 1-11. "We" don't use 12-14, if you are attempting to do this custom roms, and such might be your answer; the FCC make it difficult for people to bypass their frequency rules and such.

from what I've read the device itself is capable, but the drivers don't "allow" it. I'm in Europe, but there's so much network traffic here at my place I have to "move away" from it and CH14 seems to be the ideal alternative, Channel 13 is available here but still away from perfect. –  user144773 Mar 18 '13 at 1:59
