You have the R6400v2?
What firmware is on it?&nbsp;
What modem/gateway do you have?&nbsp;
Have you tried accessing it using the IP address?&nbsp;

Standard modem only devices.
&nbsp;
Try this:
&nbsp;

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 computers and rest of network.

&nbsp;
This is timed to let the modem get an Internet connection before the router tries to connect.
&nbsp;
Your initial description of what is happening is hard to follow. (What is this "old genie"?) Sadly "doesn't work" provides little diagnostic help.
&nbsp;
I assume that these are all wifi devices that don.t connect. What about anything wired?
&nbsp;
What do the lights on the router tell you, especially the wifi lights. And what about the Internet light?

Genie is the older app from Netgear. All my lights are on, internet is fine which is how im able to be on here. All my devices connect to 2G just fine. Its just the 5G that has disappeared. Wifi search on PC and phones only show my 2G network.&nbsp;

Yes. But which one? Mobile for Android/iOS or desktop for Windows/MacOS? Netgear likes to make these things difficult.
&nbsp;
The firmware update that allowed the Nighthawk app to work on the R6400v2 will have killed the genie.

&nbsp;
If the Nighthawk app works on your phone the genie won't. You can't get both to work.

5 GHz has a shorter range than 2.4 GHz. Maybe it got lost?

As you have a PC have you tried using a wired LAN access to get at the browser graphical user interface (GUI)?
