GX Garmin VRM

I have a GX on NMEA 2000 (pulled fuse on adapter) that works and when I plug in the Garmin with the marine network cable all data shows up great on my Garm 8617. Problem is I lose WIfi (tried my Starlink or separate WiFi from hot spot.) and VRM. Unplug the marine network cable all comes back with realtime VRM monitoring. I’m stuck. Tried auto and static IPs. NMEA 2000 still connected (no marine network cable) and VRM works. Ideas?
