I figure some of you guys are really into computer and network tech and maybe some of you have done this before What should I do to get my home Wi-Fi signal to reach into my metal shop building in the back yard? I have AT&T U-verse wi-fi router in a closet in the center of the house. I can pick up the wi-fi outside all the way to the shop building, but once inside, I lose the wi-fi signal. My phone also has trouble picking up the 4g network inside the building too, I guess its being blocked by the sheet metal. I've done a little research on wi-fi extenders and repeaters and such, but quite frankly, I'm just sort of totally overwhelmed by all the hundreds of options. Note that both buildings are on separate electrical services, one's a residential home meter and the other is a commercial meter so those gizmos that purport to use the home's existing electrical wiring wouldn't likely work since the buildings are not connected.
