For what it's worth - on both this experimental firmware and previous revisions, I can do > 200Mbps to the public internet (on my office internet connection), with 13 other users currently on the same AP as me (the APs are Cisco 3702i's managed by a Cisco 2504.) This is (obviously) on the 5ghz band, with VHT enabled. I've had issues with occasional 'dropouts' with this card, where traffic will randomly stop passing and/or ping times will jump to > 10s; sometimes it clears up on its own, somethings I have to re-associate to the AP to get it to stop. I'm hoping the new firmware and/or the newest Cisco WLC build fixes it; testing now. Borislav - you didn't mention what firmware revision you are running; if you aren't on one of the -9 builds, I'd highly recommend moving to it. I do have the following set in /etc/modprobe.d/iwlwifi-disable-powersave.conf: "options iwlwifi power_save=0 bt_coex_active=0" Once I move to 3.16, I'll probably try turning both of those features back on, and see what happens. Here's a speedtest result; I've gotten better, but this is representative of my average speeds: http://www.speedtest.net/my-result/3655207245 In any case - this card _is_ capable of decent speeds for sure! -Nate
