Stiletto SL2 won't connect to WIFI for Internet Radio

I have an SL2 that will not connect to my D-Link 4500 gaming router if the security is turned on. It connects fine if the security is turned off.

I have the security in the router set to WPA2 "personal" with an 8 character simple password. The SL2 finds the network fine and promps me to enter the password, but gives me the message "unable to connect". I have tried every combination of security modes and passwords but with no luck.

All other wireless PC's connect fine with the router security turned on, so the router is working correctly.

Any help in this matter would be much appreciated.

I'm having the exact same issue. Have you found anything out so far?
