Very weak wireless on MacBook

[p717]

Hi all, today my 3-year old MacBook's (core duo white) wireless suddenly dropped to a very weak level. I can't seem to get any signal unless I'm sitting right next to my router, like I am now. I know it's not my router because another laptop, my iPod Touch and my DS all can connect to the router as usual. I've been using said MacBook in the same room consistently for the three years since I've owned it, and never had any problems connecting before. Any idea what the hell is going on?

Any drops/violent jars lately?

Maybe the antenna wire has come loose?

How could I go about finding if the antenna wire came loose?

You would need to remove the top case (keyboard tray) directions can be found at ifixit.com. One the top case is removed, the airport card will be in the upper left. Two wires will be attached to it in your case, make sure the mini-coax connection is good.
