My old Arris surfboard router/modem combo died and so I replaced it with the G34. With my old Arris surfboard I had my laptop setup with the windows DLNA media to share media files with my Samsung TV's in my house. Worked almost flawless in discovering the DLNA and playing videos.
I activated my G34 via Xfinity and it’s been almost nothing but problems I've had to work through. I can connect to the internet and have eventually connected to smart lights and other discoverable items but the biggest issue is that my TV's no longer find the DLNA server to stream videos to my TV. It has to be a setting on the G34 somewhere but I don’t know what to change. Does it have something to do with IpV6 vs IpV4 or the UPnP? My firewall is off and everything is set up correctly on my laptop to share files.
