I have had the DIR-655 A4 fw1.21 setup with my "Rogers Express modem SB5100" for the past year and all was working fine, even have two 1522's connected to the 655.
I was away on vacation for a few days, got back and noticed I could not get any internet access on my laptops and iPhones/iPods. Checked the router and noticed the WAN section has no IP, all 0.0.0.0's and cable indicates "Disconnected", even though cable from modem is plugged into the internet port.
As a test, I plugged the cable modem directly to my laptop and it works fine, grabs an IP and internet access is great. I upgraded the 655 to fw1.34NA as well, no luck I still have the same problem.
Question is, can the WAN/Internet port be dead all of a sudden? I even cloned my laptops MAC, no luck.
Any thoughts before I toss this router out the window and buy a new one?
