Netgear Nighthawk dropping 5G wifi connection - Fixed when restarted

Which Netgear device are you using?

What firmware version do you have on the device?

A number is more useful than "the latest". There may be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.

If there is one it might also help if you told people the make and model number of the modem/gateway/ONT that sits between this router and the Internet. Is it, by any chance, also a router, with a set of LAN ports on the back?

I ask because a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.

Having two routers on a network can cause headaches. For example, you can end up with local address problems.

This explains some of the drawbacks.
