Well this UNIQUE problem makes me wonder.
My D-Link 825 router, ( I know it's not a 655), did the same thing on the same day. No Internet through the router.
I have Newwave Communications Internet, a small 3 state ISP. Kentucky, Illinois, and Missouri. So I don't know if Time Warner leases them the backbone or what.
Anyways, I called technical support, and a funny thing happened. They IMMEDIATELY insisted I try the modem DIRECTLY to the PC. Well I said that's crazy, I NEVER have that problem. I been in PC's since 1977. Many times I have called before, they never insisted like this.
Well I did it anyway, and the Internet immediately worked. In my mind I sort of began to panic, cussed my router, etc. He says check your router. I said ok, but I know it's fine. Ended call.
So here I go. I went to resetting everything, modem, router, PC, and nothing worked when I connected my modem to the router.
Finally I said, alright, repeat the process. I also changed the network cable from the router to the PC.
OMG it worked! I said well, bad cable.....never had that happen before.
I think it was just timing. Later I switched the cable back to the old one, and it worked.
So this is VERY VERY STRANGE. Are ISP's trying a new trick to see if we are behind a router? Perhaps to help tech support people know a little extra? Who knows. And why DLINK products?
Oh and the "Enable Advanced DNS Service" option had nothing to do with it, as I NEVER have it checked at anytime now or in the past.
Would be interesting if someone finds out what really went on that day.
