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.

Ensure WMM is enabled on the modem. If any Beamforming is availalbe, enable this as well. Also set 40Mhz only co-existance.

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.
