I lost the username/password for my SB8200. I’ve tried several suggested ways to factory reset it, but it does not reset the username/password back to the default.
I’ve tried:
- power cycling it
- pressing reset button until front lights flash - 10 seconds.
- pressing and holding reset button for 30 seconds
- unplugging co-axial cable, and performing the above steps
- unplugging co-axial cable, and ethernet cable and performing the above steps
- unplugging co-axial cable, pressing reset for 30 seconds, holding reset and unplugging power for 30 seconds, still holding reset and plugging in power for another 30 seconds
- leaving it totally unplugged overnight for 10 hours
None of that has worked. Are there other options? It is under warranty until 2027. It’s never been registered with my ISP. Arris online chat never appears to be online, I’ve been trying for days.
