I have a version 1 sb8200 and I just bought a v3 to see if potentially my 4 to 5 year old modem was starting to fail. When hooking up the new modem it never got any downstream signal or showed more than 1 down or upstream channel at a time in the access page.
The isp (optimum) had said they had everything provisioned on their end for the new modem, but it seemingly would never act like it was getting signal to pass internet through. I should mention, when plugging the v1 modem back in it instantly had internet again without it being re-provisioned.
I’m wondering if there’s some way to tell that the modem is faulty before returning it if it so happens that my old modem isn’t failing.
