Hi all I was wondering if someone could tell me the correct firmware version for Arris SBG6782-AC wireless gateway? I'm bought a factory refurbished and it has firmware SBG6X220.127.116.11.0-GA-05-809-NOSH. Tried to activate over the phone but the online light on gateway is constantly blinking so I can't receive the firmware update from Comcast because I have another gateway and it's on firmware D30GW-EAGLE-18.104.22.168-GA-00-NOSH which has no conectivity issues at all.
I own my own modem as well but cannot update it myself, I've been told by Arris and Comcast that only Comcast can do the updates. That said, I have the same version as you but I wouldn't guarantee that it is current.
