What happens if you are using the "plain vanilla" Starlink router, but have a mix of network devices-- some with an assigned IP, and some using DHCP?
On bootup, everything works fine on my system. Locally plus also remote access from an off-site location. But after a while, remote access stops working. When that stops working, my wired LAN seems fouled up as well. I'm using the Starlink router, ethernet adapter, then into a network switch that connects to various things. No 3rd party router.
Some of my cameras/camera devices want a fixed IP. But if that is buggering the Starlink lan I will have to figure out a workaround. ???
