Cannot Reinstall AC1750 EX6400v3

Several weeks ago, I purchased and successfully installed the AC1750 EX6400v3 as an extender to our network. It worked flawlessly until we had an internet outage during a severe storm last week. Once...

Thank you for your reply. Yes, I did do a factory reset. And when I attempt to set up a new installation, I get the same "Extender Not Found" message. When I first open the Nighthawk app, I get a message "issues connecting with 'SpectrumSetup-A0' message with instructions to go to Settings > WiFi and join your Router's WiFi network. My phone is already connected to the router via WiFi. I've had this extender long enough that I cannot return it for another one at the store where I purchased it (I've thrown away the packaging). The extender shows the Power LED, the WPS LED, and the Client Link LED lit up. The Router Link LED is not lit up. Before the outage, all of the LEDs were lit up.

 

I have no idea what else I can do to reinstall this extender. And we need it for my granddaughter's WiFi connection.

 

My computer is a Windows 10 computer connected to the router via an ethernet cable.

 

What am I missing here? Thanks.

You're installing with the app? 

Are you on ios/mac? If so, make sure icloud relay and private mac/ip address is disabled. 

 

Have you tried hardwiring the pc/laptop into the extender for setup? If you do, make sure the laptop/pc has the wifi disabled so its not defaulting back to the wireless connection.

    Thank you for your reply. I cannot access the mac/ip address to see if it is abled or disabled. I only can access the router through the Spectrum app on my phone, and it isn't as accessible as I would like.

     

    Yes, I'm attempting to install the extender with the Nighthawk app. 

     

    I'm open to installing it through hardwiring it to my computer, but I probably need some step by step instructions for it. Any idea where to look for those instructions which are specific to the Netgear AC1750 EX6400v3?

     

    Thanks.
