zdravím , mám problém s WPA šifrováním ve fedoře 9. Při použití šifrování se podstatně sníží rychlost a to na polovinu i více. Máte někdo podobnou zkušenost.
Pod woknama na stejném notasu to jede normálně.

ve /var/log/wpa_supplicant.log nic neobvyklého.

A nestalo by za to zkusit ten novy firmware?

firmware aktualizován rychlost stále poloviční ,oproti bez šifrování.
