Help! Trouble getting online w/wireless network.

I’m at wits end and am hoping a fellow doper can assist me. I am not terribly versed in computer verbiage, so I apologize in advance.

I got a new laptop (HP) about a year ago and have always had trouble getting online using my roommates wireless connection (DSL). Here’s what happens:

I click on my connection and the computer attempts to connect. About a minute later, it says, “Connected”, then immediately, the list of available networks disappears and starts looking for other available networks. My signal strength says “low” or “very low” yet, I am not able to get online at all.

I click on “repair” and after a few minutes, get the following message, ‘Windows could not finish repairing the problem because of the following: renewing your IP address”. I have a friend who is pretty smart when it comes to computers and he could not figure out what was wrong.

At the suggestion of my friend, I plugged the wireless connection (ethernet?) directly into my laptop and was still unable to get online.

It seems that my computer goes thru spurts; sometimes I can get online with no problem at all, but for the past week have not been successful. I’m not sure if this has anything to do with it, but my next door neighbor had a wireless network set up and I used it sometimes, but they’ve moved as of last week. It’s probably just a coincidence that I’ve not been able to get online since the day they moved. (I’m posting this from a school computer).
