Declined internet speed, high rate of uncorrected errors shown in modem (SB8600)
Hello, recently I have had a decline in Internet speed and increase in latency. On my amplifi alien router I used to get consistent 920Mbps+ speed test results on my Gig plan. Now I cannot get over 800Mbps and there is a lot of latency. I read in another post to check for open coaxial connections, splitters, etc. The line that I have coming to the house goes directly to the modem. I have attached a screen shot of the high uncorrected error rates from the SB8600 modem. Can someone please help me? I have already spent hours and hours with customer support. Everyone tells me that my connection from their side is "good". Thanks..

@jbmk18 Thanks for posting to the community and sharing the screenshot. Hearing the service is good but seeing the issue can be concerning. We're happy to help isolate the cause and troubleshoot. Does this also happen while directly connected to the modem? If you get the right speeds there that confirms the service is good. If it underperforms, then we need to troubleshoot there and the service further.
