Ciao,

mi pare strano!

hai provato anche con un "iwlist scan" ?

Anche "filosoficamente parlando" mi sembra comunque assurdo...

Ho scoperto una cosa strana sulle schede wifi

Ho appena cambiato router a casa e siccome ho interferenze da parte di altre reti (6 nelle vicinanze) ho impostato il canale del wifi su 13 pensando che fosse più libero. Effettivamente su quel canale funziona tutto bene. Ho un portatile con win7 e ubuntu.Con win vede la rete e si collega mentre con ubuntu (ma ho provato anche con un paio di livecd) non vede nemmeno la mia rete. Abbassando il canale sotto il 10 compare magicamente la rete.

Ho cercato in rete e ho scoperto che lo standard USA prevede 10 canali mentre quello Europeo 13. Quindi vuol dire che linux setta la mia scheda secondo gli standard USA.

La soluzione dovrebbe essere editare il file /etc/default/crda e impostare REGDOMAIN=IT

Non ho ancora provato quindi non so se è esatto

Qualcuno ha già sentito di questa cosa?
