Signal shows 4 bars, but MacBook is actually disconnected
MacBook is only a week old with all of the updates applied, including 10.4.10.
MacBook will boot up connected to the home network and I can use Safari to surf the internet just fine. After a period of about 5-10 minutes, the MacBook will no longer browse the internet even though the singal meter shows that I am still connected to my home network with 4 bars full.
Checking my router with another computer, I can see that the MacBook is no longer connected to the router even though the MacBook claims that it is. For another test, I've checked my router as soon as I turn on the MacBook and the signal quality coming from the MacBook hovers around 65-70% even when I place the MacBook right next to the router. My other PCs get around 85% rooms away.
Turning off Airport and then reenabling it results in the MacBook no longer being able to detect any wireless networks at all even though there are usually around three at my location that I can detect using the survey feature of the DD-WRT firmware. These other networks use different channels, so interference seems unlikely.

I have tried reformatting and reinstalling Mac OS X several times, but this problem seems like it is hardware or related to the 10.4.10 update because the problem persists after reinstalls. I will test the connection with 10.4.9, without updating to see if the problem is software soon.
Being a Windows guy, any help from some Mac Pros would be greatly appreciated!
