Cable Modem Issues - Netgear CM3000 Event Log - Performance
Good Afternoon,
Others have created this post experiencing the same issues, but I was asked to create my own post. The modem was recently installed to replace a CM2000. Contact was made directly w/Xfinity via phone call to ensure it was properly provisioned. I've waited a few days to view the event log and see if the messages I was getting before on the CM2000 continued on the CM3000. I'm signed up for the Gigabit X2 plan, but performance fluctuates when running speed tests. Those tests are performed wirelessly but right next to the main router (mesh system). I upgraded the internet plan in part because of a promotion but in conjunction with the key fact I've switched to streaming on the TV sets. Not so much lately, but there has been pixelation on the TV's when viewing and yes, they are all new, current smart TV's. The log reads as follows. I can provide more information upon request. Thank you.

Added note regarding equipment and performance variances - I'm also using the TP Link Deco BE65 Pro mesh router system - 3 routers total. Connection to modem made with CAT 8 cable.
