[ath9k-devel] Enabling 4.9 GHz

[Pannirselvam Kanagaratnam <pannir@xsmail.com>]

Adrian,

I got the db.txt modified.

root at p1023:/usr/sbin# iw reg get
country US:
         (2402 - 2472 @ 40), (30, 0)
         (4940 - 4990 @ 20), (20, 0)
         (5170 - 5250 @ 80), (20, 0)
         (5250 - 5330 @ 80), (23, 0)
         (5735 - 5835 @ 80), (30, 0)

However, I am unable to set the frequency for 4950 MHz.

root at p1023:/usr/sbin# iw dev wlan0 set freq 5180
root at p1023:/usr/sbin# iw dev wlan0 set freq 4950
command failed: Invalid argument (-22)

Anything else I need to do?

Regards,

Pannir
