Internet signal on/off since airport update a few days ago...

Hey, I hope someone can help me. I updated my airport card software a few days ago, and ever since then, my connection has been working, then not working... mostly not working. I don't know if I can fix it, but I'm hoping I can. Has this happened to anyone else? Or is it just my airport card?

Thanks.

I'm experiencing the same problem. Apparently this has happened to quite a few people since the Airport update...
