Dotaz: Ubuntu 9.04 - wifi - dostupné kanály

[Václav Pávek]

Zdravím,

mám menší problém s  Intel Corporation PRO/Wireless 3945ABG. Bohužel mi nejde kanál s 5.5 GHz ikdyž by jej karta měla podporovat. Nan netu resp. Ubuntu fóru se něco podobného řešilo, ale ani jeden z postupů nefungoval.

jádro - distribuční:

2.6.28-14-generic #47-Ubuntu SMP Sat Jul 25 00:28:35 UTC 2009 i686 GNU/Linux

lspci:

03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

iwlist wlan0 channel

wlan0     20 channels in total; available frequencies :
          Channel 01 : 2.412 GHz
          Channel 02 : 2.417 GHz
          Channel 03 : 2.422 GHz
          Channel 04 : 2.427 GHz
          Channel 05 : 2.432 GHz
          Channel 06 : 2.437 GHz
          Channel 07 : 2.442 GHz
          Channel 08 : 2.447 GHz
          Channel 09 : 2.452 GHz
          Channel 10 : 2.457 GHz
          Channel 11 : 2.462 GHz
          Channel 12 : 2.467 GHz
          Channel 13 : 2.472 GHz
          Channel 36 : 5.18 GHz
          Channel 38 : 5.19 GHz
          Channel 40 : 5.2 GHz
          Channel 42 : 5.21 GHz
          Channel 44 : 5.22 GHz
          Channel 46 : 5.23 GHz
          Channel 48 : 5.24 GHz
          Current Frequency=2.412 GHz (Channel 1)


 Prý se to dá řešit option v /etc/modrobe.d, ale to mi nefunguje: sudo modprobe cfg80211 ieee80211_regdom="CZ"
 

Pokud jste tuto věc někdy řešili a funguje tak děkuji za pomoc.
