Okay,

I live in a basement suite and i share wireless internet with my land lord up stairs.
he says there is nothing wrong with his router.

a couple of months ago i got a labtop from my school.
well the internet was working fine and then a couple of days ago it wont connect to the internet.
i have tried to reset the passwords and i even got my landlord to turn off the
router and all that jazz, and nothing will help.

my boss says that its vista and they have updates or something that screws up the network card...

i dont know but i really need help because i need the internet for school...

PLEASE PLEASE PLEASE HELP MEEE

Try doing a system restore to before the problem started.

[HE:LLPPME]

how do i do that and what are the consequences??

[JJ 3000]

You won't lose any data. It will just restore your computer to the way it was, before the problem started. All of your music and pictures etc.. will remain intact.

To perform a system restore in vista:

Sometimes, such details make a difference. 

A lot can happen in a few weeks.

Did you install any programs or download anything right before this started?

[HE:LLPPME]

nopeeee

Should check that your wireless card is fully compatible with vista too
