Query: A good product function-wise, but a big disappointment when putting into use

This product is a good for my need: 802.11N and a built-in media server to serve the D-Link DSM-320 media player I bought. The built-in ftp server and remote access to storage is also I want.However, this unit doesn't provide internet connectivity after setup. The setup procedure is straightforward and easy to follow. I can see the router obtained the DHCP IP address via the cable modem. But in the end, I cannot reach internet from my LAN PCs. It appears the NAT function simply breaks.I am on the latest firmware. I am waiting for the response from Linksys Tech support before I can decide what to do next.A big disappointment considering the band recognition Linksys receives.
