I have a most interesting situation. A very strong wireless signal from a neighboring router (house location unknown). So strong in fact it should be in the room right next to me. I have 2 immediate neighbors, one to the north and one to the east of me (my house is on a corner). I can rule out the one on the east as she doesn't have a computer. Have a look at the screenshot below and you'll see how strong this signal is. To top it off, its wireless G. ...any ideas as its baffling me.
