I have an Arris TG1682G from Comcast/Xfinity. I was on the phone with their tech support twice over the weekend, and neither of their technicians could successfully assist me with this. Thank you!
Is this the only device you have? Or do you have a separate standalone router as well?
The Arris is the only device I have. It’s a combo router and modem.
I have the same issue. Can you send the instructions to me too?
I never followed up with them. Mine still is not working.
