Problems seem to be:

 

Extender does not reconnect to router after power outage.

Extender loses name after power outage and reverts to prior name.

Does not connect to router through pressing WPS button on router, although Genie will make the connection.

Extender not visible on wifi network, although it is found if I manually enter SSID.

Is this in wifi repeater mode or wired wifi access point mode?

Power cuts are a nuisance. When the juice comes back on devices can connect in the wrong order. You extender may come on too early for the router and/or modem that feeds the router.

It may help to reboot the whole network in the right order.

• Turn off and unplug modem.
• Turn off router and computers.
• Plug in and turn on modem. Wait 2 minutes for it to connect.
• Turn on the router and wait 2 minutes for it to connect.
• Turn on the extender and wait for it to connect.
• Turn on computers and rest of network.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

WiFi Range Extenders & Nighthawk Mesh - NETGEAR Communities

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.
