Enable only 802.11b/g in a 802.11n in atheros wireless card

Question

I sometimes connect to a defective wireless AP in my office, whose 802.11n is somehow faulty. My Maverick netbook has an atheros AR9285 wireless, which supports 802.11n and wants to connect the AP with 802.11n, failing.

I managed to fix the thing in Windows by disabling the 802.11n mode and enabling only 802.11b/g. Is there a way to do the same in Maverick?

Solution

Researching here on the linux kernel wireless page for your driver the 'ath9k' shows:

http://wireless.kernel.org/en/users/Drivers/ath9k

That there is no way to switch off 802.11n support for this driver, not unless you modified the code and recompiled. You should report the issue of this missing feature here:

https://bugzilla.kernel.org/buglist.cgi?query_format=specific&order=relevance+desc&product=&content=ath9k

This guy here shows how he disabled 802.11n in ath9k, but it might be a little hard to do:

+1 - Hilarious that 2.5 years later, I too want to disable 11n in my Ath9k card for the same reason.
