Extender Problem

I have 3 AT&T AirTie 4921 Extenders but 2 are offline.  I tried re-pairing (following instructions) but the green light on the 2 offline Extenders continues to blink.  They both worked fine some 2 weeks ago.  Any suggestions?

All my devices are now running through the main router and the one on-line extender.

How to pair the 2 offline extenders????
