Hello, All!
I've just installed Arch on my bran new X201
Everything looks OK except wireless network.
I've managed to configure, using Network Manager Applet
Normally it works. But time-to time (for example if I live laptop unattached for a few minuts) I can' not connect to the Intenet.
NetworkManager shows that I've been connected to the wireless network.
Ifconfig shows:
wlan0 Link encap:Ethernet HWaddr 00:24:D7:69:3E:24

Then I have to reconnect, and it works.
Normally, If I run ping www.google.com, it does not failed.
Any Ideas?

Unfortunately, there's a bug in the driver or the firmware that causes issues when 802.11n is active. The workaround is to disable it.
sudo modprobe -r iwlagn
sudo modeprobe iwlagn 11n_disable=1
You can follow the bug report here: https://bugzilla.kernel.org/show_bug.cgi?id=16691

Thanks for the fast replay. I'm really glad that moved to Arch from Ubuntu: Documentation is highly relevant and forum nice.
At the moment everything looks OK. That is surprising me... May be i was just bad day.
Nevertheless thanks a lot. Will check try this solution later if problem will appear one more time.

I've tested it today. Looks like it helps. Thanks a lot
