Re: Connectivity problems with SB8200
@djf55020 @EG I am having a similar problems and seeing a lot of errors on the downstream, but when I contacted the Arris CS they stated the problem is in the low power to the Upstream Bonded Channels. Mine is reading 36dBmV an they said that they need it to be above 45. I see yours is also below at 41.
I called Xfinity out for tech to come out and basically he wasn't interested in making any adjustments to the power at the pole saying that he could not do this, DESPITE customer service saying that the techs could do it. It's heartwarming to know this guy wants to solve problems.
And this attempt was after having all the lines and splitters looked at at another previous tech visit.
One SB8200 reviewer in the recent 6 months said that he asked to have line voltage attenuted. When i brought this up with the tech he said "we haven't done this since the analog days".
Very frustrating to say the least especially during this period of quarantine.
I have asked to use a Xfinity modem in the meantime and do not experience the dropped internet problems so have pinpointed this power issue as being the problem. But no one to help me...
Any other advice is appreciated. Want to hear others with the power issue and what they did to resolve - if any.

I never did get the problem corrected with the 8200. Had the tech come back to the house and they found nothing wrong. They escalated to a higher level and they too found nothing wrong, yet my connection continued to drop every day or two. As a last shot I replaced my SB8200 with a Netgear CM1100. I still see the same error messages and almost identical signal strength levels on this Netgear modem, but the drops have been significantly reduced. The only thing I can assume is that the netgear just handles it better than the Arris. It's not 100% fixed but better than it was. Until then, I wait and eventually someone will figure it out.

They are wrong. Only the Comcast plant / engineering specs matter;

So I am at a loss to undertsantd what is causing this. I have used this out of the box for 4+ months no issues. now i get dropped internet in the middle of the night (low useage). When the drops happen its happening more frequently and for at least few minutes or more. Many times the SB8200 lights ae all solid, and its my router that indicates that there is a lack of internet (amber light).

@djf55020 I am in the same boat. I purchased a CM1100 to see if this is any better but haven't put it in service yet. I little disconcerting to know that you are experiencing drops still with the new modem.
@EG do you think there needs to be maintenance at the pole (edge of property). The first tech said that five homes were connected to 4 ports (therfore two people were splitting a port). They said that they would have them do maintenance but i have yet to see anyone come by.

Possibly. Can't hurt.
