I use WPA2 Enterprise when this happens.  My username is simple, but my password is long and includes many special characters.  A verbose lspci of my wifi card is below.  I also use a docking station, and network manager.  Is anyone with this bug NOT using the Intel 4965AG, rev61?  

What 'Type' of WPA2 are you all using?

My access point is some blue, NetGear, small business WAP.  The same subnet is in use wirelessly and on the wired lan.  What access points are we using?

Could this be some switching loop?

I will try to cause it with high network load.  At home on WPA2 Personal, and Monday, at work.

On the topic of graphics cards, I'm using an Quadro FX 3600M vbios version 62.92.2b.00.03.  Is anyone seeing this error without proprietary graphics drivers?
