[ath9k-devel] Hardware or software limitation?

[Mihai Moldovan <ionic@ionic.de>]

Hi Seth,

it is both, really.

Both cards likely have a world roaming regulatory roaming set in their EEPROM
(check dmesg...). On top of that information, restrictions for your current
country are added.

You cannot bypass the card's EEPROM value without hacking the kernel source
(well... with hacking, yes, you could, there is a patch, and I do that as well,
but always within country law.)

Note that "no IBSS" in the iw list output also means "no beaconing" and hence
"no AP mode".

AP mode possible on those 5 channels with the second card, but the first one has
"no IBSS" set on all non-disabled channels (probably due to a preconfigured
world regdom in the EEPROM chip.)

Best regards,


Mihai
