I don't think this will work for me. I have my Starlink modem in my house and I want to get the signal to my wife's school room, which is a different building with a different power source. I have an ethernet cable running from my house modem to the school. I want to find an extender or booster I can put in the school room and plug the ethernet cable into and have signal. Living totally off grid and my buildings are cement block. Any other ideas? Thanks
