I have Strlink in my main barndominium and would like to connect it to an outbuilding, second barndominium, that is 150 feet away.  My current plan is to get a starlink ethernet adapter, run cat 6 in pvc to the other building.  Two questions:  what do I need to connect to the ethernet cable in the outbuilding?  I also need to then get the signal to another room in the outbuilding but the walls are metal.  Do I need multiple wired access points, a second WAP, etc.  Appreciate any help you can offer!  Thanks!
