Please make sure that it is using correct UHD library.

If you're using an Ethernet switch - try changing it. Some people
reported issues with some switch models. You could also try changing
an Ethernet card - we had issues with some JMicron based NICs.

UmTRX doesn't support 100Mbit cards and supports only a subset of 1GbE
specs, so some cards and switches may be confused.

What may help to debug the issue is a Wireshark capture of what
happens on this Ethernet connection.

What have you changed for it to stop working?

No, there is no way to reset to defaults, other than writing values again.

Which values did you change?

This LED is not implemented yet.
This is for a future software upgrade. :)
