I got it not to long ago, and I literally have to force it to want to visit any web page. I keep getting Server not found not found errors on Firefox.

It's probably a weak wifi connection. Try connecting it directly into your modem?
Make sure the router is using the latest firmware.
Make sure the laptop is using the latest wireless card driver.
You can also change the channel the router will use for your wireless network. Some have "auto scan" which will check for the least crowded channel and set up your network there.
How many bars do you get for the connection quality, anyway?
