Sounds like the wrong driver is being loaded. What does lsmod say?

Just a side note, WEP is not very secure due to the static keys it uses. Have you thought about using WPA2?

Will look into it...see edit –  marabutt Oct 12 '12 at 22:05
    
ath9k_hw,ath9k_common,ath9k are the Atheros drivers. My TP-LINK adapter uses the same modules. Take a look at this post, it may point you in the right direction: ubuntuforums.org/showpost.php?p=5711824&postcount=6 –  Craig Oct 12 '12 at 22:44
    
The problem seems to be with connections that are added, the connection I had before I 'upgraded' are OK –  marabutt Oct 14 '12 at 22:24
