Netgear CM2050v not working with Xfinity stream

[CSMoore]

My Xfinity stream is no longer working. Have Netgear CM2050V. Internet works fine. Used to work fine, but something changed. Guys and menus work fine, but Xfinity stream of video just has 3 dots pulsing. It seems the video str is not getting through. Ideas to try?

The CM2050v doesn't block anything. Its a modem only device. 

It'd be the router blocking/preventing something. 

What router do you have?

Thanks, understood.   Just wasn't sure if there was anything at all within the modem, as saw some of the info on Netgear Armour.  I have Linksys router, nothing changed in a long time on router. 

I'm pretty sure it is something on the Comcast side of things, as nothing changed on my end. 

Also further debugging, I see it is just hanging only on my WiFi for in-home channels, and the to-go channels work fine. 

Menus and everything is ok, just doesn't show the video streaming.  All other apps streaming ok too.

Netgear Armor would be on a router, not the modem. 

You could try a different DNS provider. Or check on the linksys forums for help with their device
