Comcast turned my ARRIS SB8200 into a BRICK
My Sb8200 was working fine, albeit with a few occasional reboots required to reconnect to the internet. By simply unplugging the power cord and then reinserting for a reboot.
Yesterday Jan 15 2020 I could not get onto the internet. I rebooted the SB200 with the power disconnect and reconnect! STILL NO INTERNET!
Contacted xfinity support, and the Agent told me that the Cable modem was OFF LINE!!!
But it was not?? After many checks the modem was still not working properly and I still did not have internet. I remembered that I still had an older Motorola Cable Modem SB 6121 , asked the Agent to allow me to install it and gave her the Sb6121 mac address, Bingo the internet was back .
Since I had spent over $100 for the SB8200 I contacted ARRIS the manufacturer. The Agent politely when thru a series of questions, and then asked me if my ISP was comcast , I told the agent yes I was, he told me that this morning many many Comcast SB8200 were also experiencing the same issue.. He told me to power up the Sb8200 and then to find the RESET pin hole on the back of the unit which will reset the unit to factory specs. The cable modem was reset, I then called back xfininty support and got them to put in the Prior SB8200 mac address. After a few test the agent indicated that the modem was still showing not on line. SO i had to reinstall my SB6121. which then worked as it should.
Called back ARRIS and was told that they are writing for XFINITY.Comcast to resolve an issue allowing the SB8200 to work as it should!!
Arris would not supply a replacement or attempt a repair until Comcast resolved the issue allowing the SB8200 to work!!!!
So, I am writing this so others may be aware of the ARRIS SB8200 issue.
