Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. Tried the same with a Linksys USB network adapter. Both failed to authenticate.
Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok.
Would appreciate some diagnostic guidance and insight. The following is the result of the analysis script suggested in the thread http://ubuntuforums.org/showpost.php?p=10564143&postcount=7

Would appreciate insight on how to chase this down.
