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.
Thanks for the reply. I appreciate the assistance, but I'm trying to understand what any of this has to do with my problem. I don't mean that to sound antagonistic. I really don't understand why every tech support person I've spoken with starts troubleshooting WiFi with me when the problem exists with a direct line to the router.
When the modem/router is working properly, my WiFi is flawless. From what I can see, there is no problem with WiFi at all.
Has a factory reset and setup from scratch been performed since last update?
Does this happen with a different wired PC or laptop?
Swap LAN cables to compare between modem and PC. CAT6 is recommended.

Yes, I've done a factory reset several times.
Yes, it happens on different PCs/Macs wired directly into the router with different cables.
When the problem happens, it's system wide--the wired and WiFi connections all drop speed. Upon reboot, they all go back to their normal speeds for awhile then the cycle continues.
