Comment 4 for bug 664414

I have a similar problem, but I'm not sure it's exactly the same.
I have a Lenovo W510, I think the card (from lspci) is
    03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

I can connect fine at home over WPA2 wifi, but at work we use LEAP, and this won't connect. The error I have in kern.log is

 phy2: Selected rate control algorithm 'iwl-agn-rs'
 ADDRCONF(NETDEV_UP): wlan0: link is not ready
 wlan0: authenticate with xx:xx:xx:xx:xx (try 1)
 wlan0: authenticated
 wlan0: associate with xx:xx:xx:xx:xx (try 1)
 wlan0: RX AssocResp from xx:xx:xx:xx:xx (capab=0x431 status=13 aid=0)
 wlan0: xx:xx:xx:xx:xx denied association (code=13)
 wlan0: deauthenticating from xx:xx:xx:xx:xx by local choice (reason=3)
 wlan0: authenticate with xx:xx:xx:xx:xx (try 1)
 wlan0: authenticated

 wlan0: RX AssocResp from xx:xx:xx:xx:xx (capab=0x431 status=13 aid=0)
 wlan0: xx:xx:xx:xx:xx denied association (code=13)
 wlan0: deauthenticating from xx:xx:xx:xx:xx by local choice (reason=3)

eventually
Basically, I don't ever get any connection, continually failing. The workaround above doesn't make any difference, but it's not an 802.11n network anyway, I think it's g. I believe that this worked at 10.04 without any patches, but I cannot swear to it.

Thanks,
Chris
