Trying to use the built-in wifi for my Lenovo ThinkPad, I am having troubles connecting to networks. Specifically, right now I'm trying to connect to an open network at school. Going the manual route I do
[root@lappyICSL ~]# ip link set wlan0 up
[root@lappyICSL ~]# iwconfig wlan0 essid NETWORK
[root@lappyICSL ~]# iwconfig

Power Management:offand wlan0 has no association. The happens most of the time for this network, but not always. I get similar results connect to other networks where it sometimes works but usually fails. Note that wlan1 (a USB wifi adapter) is already connected just fine. Also, if I go to windows the built-in wifi works just fine.
I'm not exactly sure where to start tracking down the problem. I did see this bug, but I'm not sure if that's my problem or not. The suggested workaround of disabling 11n in the driver doesn't work for me.
Here's potentially relevant info:

Did you solve your problem?
I have also problems with my wifi on the x230i wich has the same card like yours.

Sorry, I honestly don't remember if/how I got around that issue.
