Reminds me of when my dad bought a new laptop.
I had it here at my house to get it setup, apps loaded, and all data transferred over from his old one.
While I was setting it up I enabled the wireless card just to make sure it works... but  I never disabled it.  (He still uses dial up... ugh)
One day he calls me and wants to know why when he goes to a site it's alot faster than when my mom goes to a site (from her desktop... which is relatilvey new)
Beats me... so I stop by.
He dials in.. and sure enough everything loads pretty quick... my mom... zzzzzzzzzzzzzzz.
I look around and notice he's attached to a wireless network... and getting a good signal.
He was, unknowingly, attaching to the neighbor's wireless and it was overriding the dial up.
The good part is, I made a few extra bucks adding security to their neoghbors router... bad news is.. no more free "high speed" for my dad.
Note:  He wont get cable/dsl/etc.  He just doesn't want to pay for it.  I try to convince him every so often... but he doesn't listen.  lol
