Does the NOK 5G21 Gateway have a bug in the LAN connections?
See this for an intro: https://community.t-mobile.com/tv-home-internet-7/intermittent-service-t-mobile-5g-43972 I have reason to suspect a problem or bug when a device is connected to a LAN port...
The OP asked about the Nokia, so my reply was about that. Sorry to hear that the Arcadyan has that problem. I was going to see about getting one. If any other Arcadyan owners are experiencing this problem, it would be good to get a thread going about that gateway. Perhaps you could post your experience, Unix_User, under a new thread with Arcadyan in the title. I also have an ATV, and it streams 4K videos perfectly via the ethernet (into a switch, then to the gateway via ethernet cable).
The problem you describe can also be caused if your ATV had a static IP address that you were using with your previous router. The T-Mo gateway uses a 192.168.12 subnet that none of my previous gateways used (cable or DSL). So, for example, if your ATV had a statice address in a 192.168.1 or a 10.0.0 subnet, then the gateway would never see the ATV. I've read, but not experienced, that some ATVs had trouble getting a dynamic IP address and needed to have a static address set for a subnet used by the router. I only mention these latter two causes to suggest that it may be something with a setting in your ATV, rather than a bug in the gateway. Just something to check.
The cable being used now in a test is white, 4ft long, flat CAT.5E this cables works fine when used with the my WiFi extender that's connect to our DSL system. But the same cable used to connect to the gateway sees up/down, up/down, up/down errors over and over,
I have a lot of cables around here and believe this is the one included with the gateway.
At the same time, my Surface is connected to the gateway by WiFi and is solid, seeing a continuous connection, streaming a radio service in which is playing fine…
One more detail, when I set this up this morning I used that cable and initially saw total stability as I Played around with it all for an hour or so. The I repowerd the device as I was doing stuiff and the instability was there.
