Some steps to try:
1. Turn Airport off and back on, see if that stabilizes it. Or restart and see if it persists.
2. Create a new location in System Prefs->Network, and see if it still happens.
3. Unplug and replug your modem and router (let them sit for ten seconds) to reset them, just to be sure.
4. Go to a wireless hotspot--local coffee shop or library or something--and see if it happens.
If after all that, you're still seeing the issue on multiple networks and multiple set-ups with your machine, then it may be your card and it's worth a call to AppleCare or a visit to the Genius Bar.
