SB8200 drops DOCSIS3.1 off and on throughout the day
Upgraded to 900down/25up plan, needed to update to a DOCSIS 3.1 compatible modem. I upgraded to the SB8200 a few months ago. Everything was going great. Awesome speeds; my router's daily speed test was averaging 800-900. Then about a month ago Xfinity was making "upgrades in our network, in our neighborhood" and over the course of a week we had several outages. Since then I have noticed my SB8200 loosing it's 3.1 connection off and on throughout the day. When ever it does I go though about an hour of horrible speeds and dropped packets. Eventually it stabilizes but my speeds will drop down to 400-600 down.
Now one of two things happen overnight: it automatically reconnects to 3.1 or I wake up to download speeds less than a meg and uploads up to 25, so I'll reboot the modem and it typically connects first try to 3.1 or it wavers and connects later in the day. I have removed the only splitter I had. I am now connected directly to the line straight off the pole. I have moved the Modem to my office where I can watch it (the SB8200 has an easy to note blue light for when DOCSIS 3.1 is engaged). I have also done a factory reset of the modem. Now reviewing the forums I think I am now getting enough power to my connection and that is throwing off my modem. Posted is my is my rates, first when in 3.0 mode, then in 3.1 mode.
