 |
|
I have a TL-WN722N(TPlink wireless card 802.11n) in ubuntu livecd , i can scan and join channel 12 or 13 but in gentoo i cant do that.
The ubuntu live cd uses the same kernel and modules , atk9k_htc , the dmesg is the same :
| Code: | ath9k_htc 1-4:1.0: usb_probe_interface
[ 6.936625] ath9k_htc 1-4:1.0: usb_probe_interface - got id
[ 7.491932] usb 1-4: ath9k_htc: Transferred FW: htc_9271.fw, size: 51272
[ 7.726981] ath9k_htc 1-4:1.0: ath9k_htc: HTC initialized with 33 credits
[ 7.919457] ath9k_htc 1-4:1.0: ath9k_htc: FW Version: 1.3
[ 7.919459] ath: EEPROM regdomain: 0x809c
[ 7.919460] ath: EEPROM indicates we should expect a country code
[ 7.919462] ath: doing EEPROM country->regdmn map search
[ 7.919463] ath: country maps to regdmn code: 0x52
[ 7.919464] ath: Country alpha2 being used: CN
[ 7.919465] ath: Regpair used: 0x52
[ 7.919846] ieee80211 phy0: Atheros AR9271 Rev:1
[ 7.920718] Registered led device: ath9k_htc-phy0
[ 7.920722] usb 1-4: ath9k_htc: USB layer initialized
[ 7.920739] usbcore: registered new interface driver ath9k |
the only diference is that in ubuntu cfg80211 is compiled as module , but the country code uses the same CN (china) but in my country is allowed to use this frequencies.
I low channels the card work fine , the problem is that wifis around me use lows channels and sometimes it causes interferences
Thanks in advance

There have been a number of comments on this problem - older kernels
(~2.6.32) worked, but none of the newer kernels AFAIK. For some reason
the ath9k developers no longer allow you to set the local country code
using CRDA; I think you'll have to live with the problem.

Ubuntu uses 3.2 kernel and it works fine and dmesg output shows that they didnt change countrycode ,my device modules is developed since 2.6.37 so i guess it can be fixed |

Compiling cfg80211 as module solve the problem
