Captive apple portal, PS4 connection issues

[nicojames]

I just switched to ATT wifi after years with spectrum. Guy hooked everything up,everything was working fine left. Few hours later the captive.apple.com message pops up on my devices  asking for a router password reset. I do that it will be fine for a while then it pops up again. PS4 wont even connect to the wifi. Again ive had this router with spectrum for years with no issues. Please help. I feel like theres a setting or something blocking the connection after a while.

att tends to use modem/router combo devices. 
it creates a double nat when you use your own router with it.

options? (only use 1)

1.Put the att device in modem only/passthrough mode. Doesn't always go well. 

2. put the netgears IP address into the ATT devices dmz. 

3. put the netgear into access point mode.

Now when I try and log into the router It won’t let me sign in. I reset the password go through all the steps “ it says password reset successfully” hit the log in button and nothing all I get is a 🔒 with a line through it. Any thoughts?

Try a different pc/laptop? 

Try a different browser? 

Maybe reset the router? (push and hold reset for 7-15 seconds)
