Netgear C6300v2 - Comcast/Xfinity Speed Problems not WiFi
Issue My C6300/AC1750 cable modem/router (Docsis 3.0) is having constant speed problems on Comcast/Xfinity. WiFi is fine on both 2.4 and 5.0GHz. The issue is with the speed as tested by speedtest...
Thanks for the replies. Some were useful, some not. I got a notification that one was accepted as a solution. Not sure how that happens because I didn't do it and it certainly wasn't a "solution". I've called Xfinity and they've agreed to loan me a modem/router free of charge for a few days to test it. I suspect it will work perfectly, but at least I'll be able to compare values of the settings.

How often can you see it?
when the speeds are slow, is the wired speeds impacted as well?
All speeds are impacted--wired and WiFi. I'm having problems posting the logs. Will post later.
