Hoping someone can help with this issue.
I installed a SB8200 modem back in August 2017. It has been working fine until recently. Now it will not connect at all. A Comcast tech came out today and said everything up to the modem looks good (signal level wise). I do not have access to the modem right now to post logs or the status page. I am wondering if just describing what the four led lights are doing will lead to somewhere. Here is what the lights do...
POWER - on and solid
RECEIVE - blinks green for a bit then turns solid green (I believe this normally turns blue)
SEND - blinks green for a bit then turns solid green
ONLINE - flashing and never turns solid
The lights just continuosly repeat the sequence above.
The Arris online troubleshooting page says a flashing ONLINE light says IP registration is unsuccessful. I am guessing that is because the modem is never connecting.
First, check if there is an outage in your area.
Otherwise, you'll prob need a tech to figure out what's happening.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
Just to update this thread... I still cannot get the SB8200 to work. Had a Comcast tech come out and tell me something is wrong with my modem. The tech watched what my modem did, unplugged my modem, plugged in a line tester, said the levels looked good, went to get a Comcast modem, plugged that in, of course the Comcast locked and worked. The tech said I would need to use the Comcast modem or go get a new modem. I am currently using the Comcast modem and my modem was unprovisioned. The tech also said in the past week or so there have been quite a few customer owned modems elsewhere in the area that have stopped working. Really frustrating. Not sure what I am going to try next.
