R7000 Wired Connection Works but No Wifi

Hello, I recently bought my r7000 router just 1 month ago, and it’s worked fine for the most part. Today, the router was working but did not produce any wifi signal. The wired systems connected to the router work fine, but there is no wifi that I can connect to. I have restarted both the router and modem, but that didn’t work. I have rebooted the router through the nighthawk app, and now on the app it says the router is disconnected, but the same thing with the router is occurring. If anyone can help, I appreciate it.
