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.
FOLLOW-UP:
I spoke to Xfinity (again) and the tech said he had found something on their end wrong.
He said there was a setting in the system that indicated I had two modems, not one as it should be. He said he'd seen this problem a lot and assured me that it would definitely fix the problem. After a reboot, the speed was at its advertised rates (whcih it ALWAYS is after a reboot).
A while later, it dropped back down.
Does his diagnosis sound right? Even if so, it apparently wasn't the only problem and didn't fix the speed issue.
