Hello, I am seeing some weird behavior with the iwlagn driver from linuxwireless.com: My Intel 5300 wireless card will randomly disassociate itself from the access point. It happens with or without security enabled. It only happens when using the 802.11n mode. I've noticed that the further away I am from the AP, the LOWER the chances of this to happen. If I put my laptop within 2-3 feet from the access point, the wireless card will disassociate itself on average once every 30 seconds. Here is some data: uname -a Linux red 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:02:26 UTC 2010 x86_64 GNU/Linux filename:
