My house is HAUNTED!!! Wireless network from out of nowhere

i know this sounds weird and stupid, but it's 100% true.
i live in a small house among a very large field, and there's no other house nearer than 50m (150 feet) from here. They don't even have DSL in this area and i'm using dial-up on the family's ancient desktop.
But around 2 weeks ago, everytime i return from school and place my laptop on my desk, it shows that there's a wireless network named linksys, with no signal level. I think it's some stupid error because i always forget to turn the wireless off when i return from school. However, just ten minutes ago i see the signal as "very low", and it's really connected!!!. I'm writing this on that network.
Again, my area doesn't even have DSL, let alone 801.02 g
anyone has an idea?

 

If there are no obstructions in the way or extra radio noise from cell phone towers, radio towers, etc- a wireless signal can easily go much further and still be usable. 150-250 feet is not unheard of, I can leech a neighbor's connection who is six houses down with no problem, as long as I stay away from trees.

 

Download and install NetStumbler and locate the access point.

 

Even if nobody offers DSL in the area, you can get DSL over DirectTV and other satellite services. 150 ft definitely isn't a rule to distance, a neighbor could have put on a third party antenna however I doubt that being that they are still using the default SSID

 

thanks for all your help
now i'm pissed, i downloaded network stumbler at 120kb/s
but it doesn't show the distance here
my IP is 192.168.1.107, i remember there's a website where they let you locate by IP address, anyone knows what it is?

 

Actually the 2.6ghz signal that 11b/g has a range of several miles in the open. The only way to determine where, is move around and watch the signal strength.

You can not locate private IP address only public.

You need netstumbler + a GPS unit to be able to locate the access point

 

With NetStumbler running on your laptop, go outside and start tracking. As you get closer to the source, the signal will get stronger. With houses in your area so spread apart, it should be pretty easy to pinpoint the location.
