Does the NOK 5G21 Gateway have a bug in the LAN connections?

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.

 

That seems to have been the problem with me! Yes the PCs adapter had an IP allocated to it from my other (ADSL based) network. So connecting that to the other (TMBOB) network was asking for trouble!

I was going to reboot the PC today to see if that fixed things. It would have but I'd never have known why and would remain uncomfortable!

I simply reset the adapter and a new address was allocated.

It went from: 192.168.0.1 to 192.168.12.230 

The connection now seems stable.

Thanks for the insight!

 

 

On a LAN connection it is common practice to renew your lease (IP) when you connect to a new network. You can do this from your devices' network setting or resetting the device. Also static IP addresses from the old network will only work if the new network uses the same subnet as old. Unfortunately on TMO routers, you can't change the default IP and subnet.

Wifi manages this much better since it was designed to connect to multiple wifi networks so each time a wifi device connects, it will automatically renew it’s lease and get a correct IP assigned to it from the router.

Yes that was it. The IP address set for the PC adapter was only renewed when I reset it (or reboot the machine). TCP/IP itself has no means of detecting disconnection at the physical level.
