Dear Tech Guys,

I'm admittedly not great with computers but I'm trying to learn, so here we go:

I'm having trouble connecting to the wireless network in my new home using Windows Vista on a Dell Vostro 1400. Confounding factors:

1) My roommates are connecting without any problems
2) The computer will connect occasionally, but just as frequently disconnects so I'm using internet through the wireless in frustrating 5 minute intervals and I never know when it will decide to shut off or on again. It is incredibly spotty.

My boyfriend tried to fix it a few days ago and I'm not sure what he did or if it affected anything, but for the past few days the wireless hasn't connected at all, even for a few minutes like it was before.

3) The network sharing center shows me as being connected and getting great signal but it's clearly not. I tried all of the options it has given me---resetting network adapters, restarting the computer on multiple occasions, but it still gives the same feedback that "there is still a problem" basically. :confused:

I tried walking through some of this:
http://forums.techguy.org/networking/902843-solved-stuck-acquiring-network-address.html
and from what I can tell, everything LOOKS fine. In the past I have connected to other wireless networks without issue, though things on my computer may have changed since then...but I doubt it.


I'm not sure what to do, I have scoured the internet but to no avail. Can anyone help me? I'd really appreciate it.

Thanks, :)
Sarah
