[Bug 429748] Re: ath9k - karmic - no 5GHz networks

[Erno Kuusela]

It seems the ath9k driver restricts you to the region programmed in the card EEPROM, and many (most?) just have it
set to "world" which is the subset of frequencies that are permitted everywhere. 

There's a patch to add a regulatory domain override switch at http://patches.aircrack-ng.org/ath9k_regdomain_override.patch which looks like it should help but iwlist freq
still doesn't list the 5 GHz frequencies for me. 

(the patch didn't compile cleanly with latest wireless-compat for me, changed the line where
it errors out to say "common->regulatory.current_rd = modparam_override_eeprom_regdomain")

So assuming the bug is with the EEPROM there are two bugs here:

1) failure to provide any indication that the ath9k driver is imposing
additional restrictions

2) failure to provide an override for the bad EEPROM
