I had this extender and the adapter working great.  The adapter is in the same room as the router.  The extender is in another room.  All 4 lights were on.  3 months later, I needed to move the extender to another room.  It worked great still.  3 nights ago, I moved the extender to the original room.  The powerline LED lights up, but 10-15 seconds, it goes out.  However, the adapter Powerline LED stays on constant.  What is wrong?  I brought it back to the same room with the adapter to get the PL light back on. It lights up, steadily.  I take it back to the room where I want it and it lights up and turns off again.  I bring it back to troubleshoot it from the TP-link website.  It does not light up anymore.  The adapter PL LED isn't on either now.

HELP!!!!!
