 |
|
I've got only 11 channels, why ? I know about some restrictions refering to channels that are allowed to be used in different countries, but I believe in Europe there's no problem to use up 13 channels. I've bought my Thinkpad T61 in America, however my friend got european version of this notebook and got the same result :

Is there any way to have all channels operable, do i need to flash eeprom, i googled that some guys with exactly the same wifi-driver and 4965agn got got 13 tunable channles b/g and even 19 of a ( 13 here).
if there was such topic, forgive me, i may not searched thoroughly.

You could try to change that via a module option: | Code: | | options cfg80211 ieee80211_regdom=<YOUR_COUNTRY_CODE> |

just as a comment...
i've never seen more then 11 channels, but living in america... well you get the picture.
so, from my experience, yes you are probably going to have to flash it, that is, IF this card can do more then 11 channels(which i assume it can).
i can only say to you, read around some more laddie.
good luck.  |

Hi,
add the following in /etc/modprobe.d/cfg80211
| Code: |
options cfg80211 ieee80211_regdom="EU"
|
This was fixing the 11channel problem in Germany.

In North America only 11 are legal, and I guess this is the default for the driver.
However if you bought a hardware in US, the limitation may be at the hardware level. |

The card shouldnt be limited to the region where you bought it.
If you load the driver with on a system bought in the European Union, without these options, you will see 11bg channels and 13a channels. With the Option you will see the following:
