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". * On 01.08.2012 08:47 PM, Seth Baker wrote: > I can use 5Ghz AP mode on one, but not the other. > [...] > * 5745 MHz [149] (30.0 dBm) > * 5765 MHz [153] (30.0 dBm) > * 5785 MHz [157] (30.0 dBm) > * 5805 MHz [161] (30.0 dBm) > * 5825 MHz [165] (30.0 dBm) 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.)
