I cannot connect my new DWA-552 to my new DIR-615. Both have the latest firmware/drivers installed. The DIR-615 is setup with WPA and is on 802.11N ONLY mode. Strangely, I can connect to my Linksys WRT54GS router, and I am using this to post. However, my N router appears but I cannot connect. I put in the WPA key and it just hangs in the D-Link Wireless Utility.
