I need to set my wireless interface to 0 dBm.
When the interface is up, the minimum possible value is 3 dBm.
When I turn down the interface it is possible to set it to 0 dBm. However,
when turn up the interface, it automatically changes to 3 dBm.
It does not seam a problem of reg. Now, I am using this:
country PT:
(2402 - 2482 @ 40), (N/A, 20)
(5170 - 5250 @ 40), (N/A, 20)
(5250 - 5330 @ 40), (N/A, 20), DFS
(5490 - 5710 @ 40), (N/A, 27), DFS
This is my interface:
Network controller: Atheros Communications Inc. AR922X Wireless Network
Adapter (rev 01)
The driver is the ath9k.
Do you have idea of where this problem comes from? I am sure that this is
not a hardware limitation.
Thank you for attention
