Advice for WiFi extender

Problem with leaving and entering a building is the exterior walls tend to have the most materials that obstruct wifi. this includes, stucco, brick, concrete, metal side, metal garage doors, foil lined insulation, etc. I could go on with things that block wifi. That's why wifi tends to work better inside homes and then gets sketchy outside homes. 

Depending on the distance your trying to run to your garage, a moca adapter, powerline adapter, or even burying a underground ethernet wire might be cheaper and work better then trying to run an extender alone .
