There is a bug we know about the "fail to flush tx fifo" thing that people reports (through mailing list or bugzilla of RedHat). Can you please send the output of the kerne log (dmesg)? > Sadly I only get 2 MByte/s on N, and under 1 MByte/s G. > > I have not tried another access point in ages.

If you say that it worked, then it should still work. The issue I was thinking is the way they use some fancy feature of WiFi that no one implements (besides the wifi module of their devices of course). Also, can you please try different firmwares from http://wireless.kernel.org/en/users/Drivers/iwlwifi#Download ? I wonder if newer firmware has made things worse. You may want to try older firmware. To do so, open the tarball from that you'll download and copy iwlwifi-*.ucode to /lib/firmware. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
