Ahoj, a co Ti vypíše "wlanconfig ath0 list chan" ???

Jo a mám dojem že ve Voyage verze 0.6.xxx má pořád problém s madwifi.

Ještě před nedávnem mi to nechodilo, tak jedu na 0.5.xxx

Jestli to chapu, tak pasmo 5GHz by melo byt na karte nastavitelne,ze? Dnes rano jsem k prekvapeni zjistil, ze je karta úrenuta v pasmu 5GHz.

Zajimave je, ze ji rucne do pasma 5GHz nenastavim.

Nakonec jsem musel dat na CF stable verzi 0.5 a uz je videt, ze lze kanaly nastavovat spravne.

iwpriv ath0 doth 0

a jemu podobne prikazy. Ono si to totiz skace po kanalech jak se mu zlibi a hleda prvni volnej kanal. Taky by pomohlo "mode 1", pak to bude prepnute jen do 5g pasma.

iwpriv ath0 mode X kde X zamená 0=802.11a/b/g, 1=802.11a, 2=802.11b a 3=802.11g

Vyzkousel jsem iwpriv ath0 doth 0 pro ath1-ku a zadna zmena. Jedna vec, ktere nerozumim je to, ze tam mode 1 mam v konfiguraci v /etc/network/interfaces (viz. vypis nahore) a stejne se karta po restartu prepne do pasma 2,4GHz. Petr
