Channels 12-13 in europe

Channels 12-13 in europe

[Roberto Riggio]

Hi,

I'm using openwrt with the latest compat wireless. Is an ath9k supported
wireless NIC supposed to work over channel 12 and 13 if the country code
is set to IT?

If I run:

iw phy phy0 info

tis is what i get:

         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] (disabled)
             * 2472 MHz [13] (disabled)
             * 2484 MHz [14] (disabled)

Actually, I get the same even if I set the country code to JP,where also
channel 14 should be supported.

Thanks

Hi Roberto!

Did you do EVERYTHING as described on this page:

http://acx100.erley.org/stable.html

I once had a similar error as you have, which was due to not having
installed crda, if I remember correctly.

Just a thought of mine.

Best regards,
Dennis

Hi,

I;ve just installed the crda module and there are indeed some changes. For
example if i set the country code to US I get:

             * 2412 MHz [1] (27.0 dBm)
             * 2417 MHz [2] (27.0 dBm)
             * 2422 MHz [3] (27.0 dBm)
             * 2427 MHz [4] (27.0 dBm)
             * 2432 MHz [5] (27.0 dBm)
             * 2437 MHz [6] (27.0 dBm)
             * 2442 MHz [7] (27.0 dBm)
             * 2447 MHz [8] (27.0 dBm)
             * 2452 MHz [9] (27.0 dBm)
             * 2457 MHz [10] (27.0 dBm)
             * 2462 MHz [11] (27.0 dBm)

Notice the higher tx power. However setting the country to JP, IT, or FR 
I still get:

             * 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] (disabled)
             * 2472 MHz [13] (disabled)
             * 2484 MHz [14] (disabled)
