I have a Linksys E4200 wireless network set up in my house. I have a shop located approximately 50 feet away from the house. The house has masonry walls, and the shop is a frame building with siding. The house is two-story with the router located on the second floor. Both buildings have metal roofs. My problem is that I lose my wireless signal about half way between the house and the shop. I have tried moving the wireless router around in the house and I still cannot receive a signal in the shop. Unfortunately, I have no easy way to get a hardwire connection between the house and the shop. Is there anyway to extend the range to my shop from the E4200?
