I have a AR922X mini-PCI card in my laptop. I can connect to 2.4GHz networks easily but I cannot seem to be able to scan for 5GHz networks.

The card is capable of using the 5GHz band:
Code:

# iw reg get
country GB:
   (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


But,
Code:
iw phy0 info
only shows:

Code:

      Frequencies:
         * 2412 MHz [1] (20.0 dBm)
         * 2417 MHz [2] (20.0 dBm)
         * 2422 MHz [3] (20.0 dBm)
         * 2427 MHz [4] (20.0 dBm)
         * 2432 MHz [5] (20.0 dBm)
         * 2437 MHz [6] (20.0 dBm)
         * 2442 MHz [7] (20.0 dBm)
         * 2447 MHz [8] (20.0 dBm)
         * 2452 MHz [9] (20.0 dBm)
         * 2457 MHz [10] (20.0 dBm)
         * 2462 MHz [11] (20.0 dBm)
         * 2467 MHz [12] (20.0 dBm)
         * 2472 MHz [13] (20.0 dBm)
         * 2484 MHz [14] (disabled)


Any ideas how I can get the 5GHz channels to show up? Thanks

The regulatory domain setting does not automatically make the card 5 GHz capable. What is the output of
Code:
# iw list
