You said both had their HD's replaced recently. Was this done by an Apple personnel or a third party?
Why i ask is because the Airport Extreme card is directly above the internal HD, so maybe during the HD install a wire came loose, perhaps?
*Take a look at step 11 and you'll notice the Airport card is next to the HD*
Might be worth looking into, or you might have a bad Airport card. Have the Apple store folks look at it.
