Airport Express life expectancy?

[RockTheGlobe]

I've been having a lot of problems recently with my Internet connection dropping out. Time Warner Cable just replaced my cable modem a couple of days ago, but the problem's still occurring -- I'll be going along just fine, and suddenly my connection will drop. The Airport Express light will stay green and I'll have a full signal according to my Powerbook G4, and the cable modem will tell me it's still getting a signal from Time Warner, but the laptop can't access the Internet.

I've had the Airport Express for about 2-3 years now. Time Warner is telling me when they tested my modem (when my laptop said it couldn't connect to the Internet) that they couldn't see a problem on their end, and it was most likely the Airport Express despite the fact that its light was still green and the Powerbook was showing a connection. Should I replace my Airport?

Well, have you tested resetting the AirPort by unplugging it from the power for a minute or so?

Yeah, usually when I do that, I have to reset the cable modem as well. I was under the impression that the MAC address on the Airport Express was tied to the cable modem, and that if I reset the Airport, I have to reset the cable modem no matter what or they won't be able to communicate.

Not necessarily, but resetting them both can't hurt.
