Changed Router Wifi Password and now Iphones say "no internet connection" on 5G network

[Kiddfam]

Our home webcam was hacked the other night and it was connected directly to our Netgear router so yesterday we changed the Wifi passwords for the 2G and 5G Networks via the Nighthawk app and checked it via the routerlogin.net.  Unfortunately now we can connect our Iphones to the 5G network however it then says "no internet connected" and we can't access anything.

2G works fine but 5G is a no go.

Anyone have any ideas?

did you try clearing the network settings on the iphone?

Also, are you using any parental controls/armor? 

Are you using the "random mac/ip" feature on the device? try disabling it

So that was the solution.  Had to go into all our iphones and reset the Network Settings.  After we did that we went back into the Wifi networks, entered the new password and so far so good.

You can set WiFi Private Address feature to disable while your at home. Apple intro'd this and can cause odd problems with wifi routers. It's only needed while you travel.
