Description Of Issue
Can not login to Roon - getting network error message

If you see “Network Error” on the front panel of Lumin T2, please use a different network cable to connect to a different network port of your switch (Eero?)

But that should not prevent you from logging into Roon, that would be a totally different problem.

Hi @Michael_Gelfman.

Is there any change in behavior if you reboot (power off, wait 30 sec, power back on) your Nucleus and Networking Gear?
