I've probably stumbled onto something here where I shouldn't be, but . . . I'm trying to figure out how to amplify my Linksys wireless router's signal so that it is clear and strong throughout my 2-story home. From what I can glean, I need an antenna to relay the signal. Where can I obtain such a device? Does it have to look gray and industrial and conspicuous, like something you'd find in an electrician's workshop?
I am not a geek and have no technical training, so if you're going to answer make it simple, please.
