Internet drops multiple times throughout the day

For the past few weeks the internet connection has been unstable. I checked the modem (Netgear CM1150v) and noticed some interesting messages in the logs. I also noticed thousands of uncorrectable errors. The uptime is currently 3 days. It's plugged directly into the xfinity provided splitter. Can anyone help me out with this issue?

Re: Internet drops multiple times throughout the day

Service was steady for 2 days. Went down again, this time I was home. Checking the logs during the event there are two upstream channels not locked and the power is higher than it typically is. I provided a sample of upstream channel power when working. Not as many uncorrectable errors on the downstream channels, uptime is 5 days.

Re: Internet drops multiple times throughout the day

On 8/26/2020 I reached out to Xfinity via Twitter. Finally received a response. They claimed that the issue was resolved. My connection was pretty solid until 9/6/2020. It dropped again with the same errors as before. It dropped again today (9/7/2020), uptime is 11 days. This time internet came back but not phone. My children are distance learning and I don't have a reliable internet connection.

Re: Internet drops multiple times throughout the day

You are getting wild intermittent upstream power level fluctuations, and they go out of spec. This can't be fixed remotely over the phone. It takes *boots on the ground*. You should get a tech out to investigate / correct the problem.

 

Good luck !
