Apple TV keeps on connecting and disconnecting from wifi (within seconds)

Hello my Apple TV 4k with tvOS 17.4 keeps on connecting and disconnecting from my wifi this happens around every 3-5 seconds. When disconnected in the network menu the wifi isn’t visible on the discovery. The router is in the room next to the Apple TV and it has been working fine for a year now. But since yesterday it’s unusable. All other devices in that room have no wifi connection problems at all. Restarting the devices both the apple tv and my route multiple times hasn’t fixed the problem. I’d appreciate your help
