Ok so I just got this laptop yesterday in the mail. Upgraded to a 320gb 7200 rpm WD hard drive and thats all ive done everything else is stock. My problem is that after a few minutes of browsing my airport wifi thing will just stop working and I have to turn it off and back on so it will reconnect. I then have to keep on repeating this as it happens all the time. Anybody have any ideas of what it might be? Or do I just need to call apple. sigh... Does it at my university as well.
