I will probably get a slap from developers, which i do and do not deserve... Anyway, i was using gnome on linux for as long as i remember. And every time i have loaded nvidia drivers, i was loading gnome too. (hence, my assumption of hardware issue) Now for several days i am running xfce, pinging local computers over Acess Point in G mode for hours without one packet being dropped. Nvidia drivers are loaded, SLI is enabled, all 3 devices are actually IRQ 16... I could never guess, it looks like it was not hardware problem after all. So irqpoll option was unnecessary for me... I still have issue with connecting using N mode... It silently fails, even by manually assigning channel.
