Autonomous 2602i Won't Negotiate 1000BASE-T

I have a pair of 2602is running in autonomous mode.  One of them refuses to negotiate or form a link at gigabit speeds on its wired port.  The other one performs fine.  I have swapped the physical location of the two APs, confirming that the problem follows the AP, ruling out any of the intermediate infrastructure.  I have tried both 'speed auto' and 'duplex auto' as well as 'speed 1000' and 'duplex full.'  In both cases, the output of 'show interfaces GigabitEthernet0' shows 'Full Duplex, 100Mbps, media type is T.'  Has anyone encountered this before?

 

See below for more:

 - Have a factory defaults reset on the problematic AP and try again.

And if that doesn't help, RMA them, you have 10 years of hardware warranty.

I had considered that as an option.  Thanks!

I've tried that too.  No change in the symptom
