Losing VRM connection when moving installation

I am not sure what is causing this problem so I’ll ask if anyone else has had this issue.

As in title I loose connection to vrm when I take the boat out of the harbour.

Cerbo is always connected when in harbour.

When I take the boat out it warns about geofence and shortly after loose connection.

When I stop the boat at next harbour Vrm starts logging again.

Firmware is 3.73. Last year I had no problems with this. I have checked that other devices connected to the network has internet access.

Router is not connected to any WiFi. Only 4/5G.

Any tips?

Turn off geofence?

That did not solve it. Problem was that there was a tick to allow internet via LAN that was ticked. I assume it came in a firmware upgrade since i did not change any settings. When i take the boat out, I turn on the chart plotters. They are connected to the Cerbo. The network for the chart plotters does not allow internet access. The Cerbo is connected to WIFI, but it lost its connection because LAN becomes present when the MDF`s gets turned on.
