Hi Leon. I had the same problem at my place as I have an old villa and had trouble getting signal from inside to the back of my yard. My solution was to purchse a Belkin WiFi extender. They are cheap and work great. I put it in my back loby and now I have great signal all the way to my back fence and even inside my metal shed. My router is in my office at the front of my house. I purchsed mine at Harvey Norm. Oh by the way I an not sure I would rate myself an expert, but I do work in a computer workshop as an Electronics Comp Tech. If you asked my workmates they would use the moment to bring me down LOL.
Hope this helps
Mardy
