Boosting a signal

So I finally got laptop back today but annoyingly it wont connect to the internet. I'm using my xbox to write this. It seems it has a stronger signal than my laptop. The signal I'm trying to reach is a few floors down. My laptop is an Acer travelmate 4150 (looks old as shit) and has windows 7. Thanks in advance.

If your laptop supports it, just gen an external antenna. If not, you'll have to get a USB wifi card with a replaceable antenna, then go get a bigger antenna if the card's built in is not sufficient.
