If so disable it and connect manually. 2) Can you disable encryption on your AP and see if it works without it ? 3) Try and enable/disable hw encryption with nohwcrypt module parameter. 4) What's your signal strength/rate when you connect to the AP ? -- GPG ID: 0xD21DB2DB As you read this post global entropy rises.
