Is it possible for a computer with a wireless card to pick up a wireless router/adsl modem which is in the building nextdoor? the reason i ask is, is that a friend of mine has a situation where he's not only picking up the name of his network, but two others...which he's not familiar with. I think one is called REDEAGLE. very strange. As i thought with wireless cards there's a 40metre limit or so and for it to go thru such thick walls seems un-usual.
