5Ghz drops frequently and disappears for a while, then shows back up.  This happens daily, several times a day.

Not much to go on there.

What happens? 5 GHz LED goes off? One (or more) clients can't connect?

Then the usual boilerplate questions.

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.

Apologies for all the questions. But you can help people to help you by providing the information suggested in this forum's header:

Subject (Include model number and brief summary)
Model (Recommended - Helps the community give the best answers)
Body (Include additional detail including model version, firmware, OS and environment where relevant.)

They are there for a good reason.
