I recently purchased a new router(D-link DIR 628) to take advantage of both 802.11n speeds and less interference on 5ghz band. However, my Intel Wifi link 4965AGN onboard card seems to be having problems. I noticed my speed was only 54mbps so I set my router to 802.11n only and the network card will not connect (the connection times out and the diagnostic suggests the card is not compatible).
I have the latest drivers (18.104.22.168). I have set the recommended 802.11n settings (http://www.intel.com/support/wireless/sb/CS-030709.htm) including 802.11n mode "enabled". I also have the security settings set to the recommended WPA2-AES - and I have tried connecting with no security enabled.
I also have tried 802.11n mode on my router at both 2.4ghz and 5ghz, and the network card will not connect to either. The network card has connected fine while the router is in mixed mode (802.11a or n for 5ghz) or (802.11b/g/n for 2.4ghz).
