Hey Yall

Trying to get WiFi out to my shop which is a separate building about 60' from the house and 90' from my Fios router. Running a cable would be the best idea but It would need to pass under 2 sidewalks, down and under a 4' retaining wall, under 25' of driveway and up 16' into the shop. The biggest issue with the shop is the insulation. I got a killer deal on 2" thick foam board insulation with foil attached to one side. $4 a sheet. I used this on all the walls which are covered with 1/2" OSB and also in the ceiling with the foil facing in as a light reflector. There are no windows facing the house. I can get 2 local radio stations in the shop and little to cell phone reception. Kinda like being in a beer can.

I'm guessing I need to run cable from the router to the end of the house nearest the shop and then setup some outside transmitter/receiver between the house and the shop. Does this sound right? Is there a reliable solution for this?

TIA
Brian
