Hi! I bought Wi Fi extender for my house, the one that you have to plug to electrical outlet. I located it close to router at first and installed driver, everything was successful, but then I located it in the place that I actually needed it and it couldn't find signal from the router, even though it was not really far. I tried to plug it in every socket and it worked only in ones that are near router. I don't want to return it, may there is a way to fix it?
