We just switched to Xfinity from ATT and have a 3rd party router (Arris SB6183.) When I connected everything, my modem's receive light just continuously blinks green...as if waiting for a signal.
Do I need to let Xfinity know what pe of modem I have before it can connect??
Anny help is appreciate
Was there ever a live Comcast coaxial cable feed there at the premises ? If not fairly recently, you may need a tech out to reconnect the coaxial cable feed to a live Comcast feed from the tap.
