XWN5001 - Lights all work but no wi-fi

Does this sum up the situation?

The network Genie recognizes the adapter but not the access points.

 

Wi-Fi works in the same room as the modem.

If so, what does the "power line adapter and access point no longer work" mean?

Does it mean that the "remote" plug won't work with wired and wireless devices?

When you say "The network Genie recognizes the adapter but not the access points.", which genie is this? Desktop app, Android/iThing?

When you say "Wi-Fi works in the same room as the modem" does that mean the wifi from the XWN5001 powerline access point?

I ask these questions because they can help to pin down the problem. There also seems to be some contradiction if my guesses are correct. If "the power line adapter and access point no longer work" how come the "Wi-Fi works in the same room as the modem"?

You seem to have tried most things. If the powerline access point, the XWN5001, works in one room, then moving it somewhere else on the same mains circuit. Should work. It it doesn't I would look at the mains circuit rather than the plugs. Are you using a fancy, surge suppressing, extension block? (Netgear advises against using any extension block, but most people find that this is too cautious.)

How about a different mains socket somewhere else in the house?

Remember, when you reset the plugs you deleted any settings that you made and the thing will now revert to the passwords on the back of the plug.
