I have been using a nighthawk R7800 since October 2022. Now it suddenly gives the message no internet. I've turned it on/off, unplugged it, and reset it, but the problem persists. All lights are burning white as normal. How do I solve this?

Where do you see this message? The R7800 doesn't have a display to say things like that.
What firmware version do you have on the R7800?
A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.
It might also help if you told people what the modem is in front of this router, if there is one. The make and model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.
