LAN and Router disconnection

[IZ0JOJ]

Dear all,
first of all let me say again thanks to everyone for the continuos support you offer.

I am quite happy of my RRC - I have finally found my correct setup.

I have just one issue, quite difficult to explain but I will try.

Everytime I every xx hours my LAN crashes - I need to restart my router! because the LAN cable looks disconnected.
I need to restart again the router and then the interface get the correct IP by DCHCP.

Any hints?

Thanks

Hello to evryone,
the issue is still there.

Every 2 -3 days that microrrc is not used, the LAN cable looks disconnected. I should restart the router and then everything works again.

Can somebody tell me what's going on?

Thanks
