Hello all - I'm looking for a way to "shoot" a wifi signal directionally across a distance of about 200 feet, from one house to another. The user in the "target home" is an elderly lady with an iPad who is not computer-savvy in any way. She can use the iPad now in the "source house", but reception in the "target house" is marginal at best, and can often become unusable. Because her use will be limited, it's not really practical for her to sign up for her own internet service. But her relatives in the "source house" have no problem with her piggybacking off of their service. The source house has a wifi transmitter in the garage (coupled to a cable modem/router inside). I'm guessing that the connection between is ethernet. There is a clear "line of sight" between the garage window and the target house which is about 200 feet away. I realize that most wifi routers are designed to broadcast their signal in all directions. What I need is either a router, or perhaps some kind of "dumb transmitter" or repeater (no routing capabilities) that can output its signal in a directionally-focused stream. This is to be distinguished from something that just broadcasts in a 360-degree profile. Has anyone tried setting up such a system? Was it practical, to "shoot" a signal about 200 feet or so? If so, can you suggest any hardware? Cost is also a consideration.
