100yds you might need to get a second router. They can be set up in a mesh network.

I think I read 200ft line of sight for the Gen 2 router.

You could also rent a trencher and then burry Ethernet for hardwire in. Might be more of a project, but I’ve done it. Not too bad.

Probably not going to work. But might. I use it in van/nomad life and not sure it will work for both houses

I replaced the starlink router with an Asus paired mesh router and was able to broadcast it across the farm around 300 yards
