Wifi AP shuts off :(

Hey guys,
I’m using a Wemos D1 mini pro, and encounter the issue that the ap goes down after a few minutes.
Once started up everything works fine but after around 3-5 minutes the wifi ap goes down.
All effects keep running fine but to get the ap back online again a powercycle is needed.

Any ideas why this happens, Help is appreciated.
Thanks

Disable sleep?
