I'm not sure if this is the routers fault or the > Cable modems problem. I have heard that the 655 has problems with maintaining a connection on some ISPs using Cisco uBR routers. I know that I could not connect after updating to the latest firmware on DLinks website. I backed down to v1.03 and our connection seems to have stabilized. Definately something you should ask your ISP and DLink about, as they may want to have you run some test to collect any related info that they can get.

In an attempt to maintain connectivity from the outside, I've got one of my machines that pings my DNS server one time every minute. Haven't really had the chance to see if it's improved connectivity from the outside. I haven't had any issue maintaining a connection from the inside to the internet though. The only two things that I can think of that I altered was to allow ping replies from the WAN and hardcoded the WAN port to 100mb instead of auto detection.
