Well, here's the problem.. I've had this router for 3 days. It worked perfect the first day and I was very happy with the product. However.... yesterday I noticed that my computer had no internet connection. I looked and apparently no wireless networks were available. I reset my DIR 655, reinstalled the installation disk, and it worked fine wirelessly for about 4 hours. I don't know what to do about it. I've called Comcast and they said that everything is working fine on their part. I have an Arris modem and using a dynamic ip and dhcp. all the settings look fine. Like I said, it will work fine for a few hours and then no internet connection is found. All the lights are on and everything, so it should be working. Also, if I connect my ethernet cable to my DIR 655 and directly to my laptop, it works fine. I'm just not picking up any wireless signal. Help??? I mean, jeeze.... this is a brand new router and it's already giving me trouble.
