I bought a new 6120 a couple years ago. Never used it, was brand new in box. Recently switched to comcast internet.
I setup the modem without a splitter first so it was a direct run to outside. All the lights steady green until it reaches online, then it flashes online for a few seconds before starting over. Just loops over and over.
Had the tech come out and he said the line was fine. I googled around and it appears that other had similar problems with the sb6120. Anyway have any tips on fixes before I just trash it and go buy a new modem?
Thanks!
