Yes it is the AX8 Netgear Nighthawk Mesh Extender.
Yes I followed the procedure every time. I noticed though that after I had to do a reset on the device
it immediately showed the wireless symbol and connections to 2.4 & 5.0 GHz even before I tried the WPS
It worked originally when I first bought it and used the Cell phone app to install but now when I try that
it tries to connect the Netgear.net but my iphone does not see it so cannot get it to join.
It does connect ok with an Ethernet cable to the connect box, but that not what I need it for.
I am running out of ideas.
After I used the app for installation from my iPhone I had a lot of problems with a certificate that Netgear installed but was Untrusted and I could not get my phone to work. Had to do a complete reset to fix things
Now i am relucktant to try it again from my iPhone for the installation and not the WPS.
