Other devices (even non-N 802.11a) can see the 5ghz ssid. I am using iw dev wlan1 scan to see what is out there, and it lists all the g networks around, and the 2.4Ghz ssid on the WRT610N.

But keep in mind that will only help compliance further. Since all Atheros card already have been programmed with a regulatory domain in the EEPROM that is respected, you should be fine with regulatory out of the box with ath9k. > phy0: Atheros AR5416 MAC/BB Rev:2 AR2133 RF Rev:81: mem=0xfd780000, irq=12 Anyway you have a single band card, as iw didn't even list anything for 5 GHz. All AR5416 cards I am aware of sold use the AR2133 which is a single band 2.4 GHz radio. The only AR5416+AR5133 (with dual band radio) combos that I know of are demo cards here at Atheros. This would explain why you can't see your 5 GHz AP. If you're lucky maybe you can find an AR9280 dual band on ebay or something. AR9280s are dual bands AR9281 are single band 2.4 GHz. You can check: http://wireless.kernel.org/en/users/Drivers/ath9k to see which products ship these. Luis ^ permalink raw reply [flat|nested] 6+ messages in thread

Wrt the Reg domain. I am in AU and I can set to AU prior to ath9k being load and see the results in dmesg, but as soon as ath9k is loaded, it switches to AT. If I iw reg set again, there is no further entries in dmesg. So this could mean either it is setting AU and just not reporting it, or it isn't setting AU and leaves it as AT. Or it is AU anyway because I bought the WMP300N in AU and so the firmware is set to AU (dmesg doesn't really support this). But what is the impact if it is wrong - does it mean that I will not have access to the correct range of frequencies in this country? ^ permalink raw reply [flat|nested] 6+ messages in thread

That's because it does an intersection when ath9k loads because it detected you one compliant gentlemen so it will listen to that and compute the intersection between what ath9k has and what you previously set. After that further user regulatory settings are ignored by the user as the intersection was computed already. cfg80211: Current regulatory domain intersected: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm) > So this could mean either it is setting AU and just not reporting it, or it > isn't setting AU and leaves it as AT.

Its not wrong, its behaving appropriately and as expected, you asked for one regulatory domain, the card has another one so it computes the intersection and uses it.
