AX1800 WiFi Mesh Extender (EAX20) keeps disconnecting from Verion Fios router

Sorry if this has been mentioned before, this is my first time posting. I have a AX1800 (EAX20) WiFi Extender hooked up to my Brand New Verizon Fios Router. The Router and Extender are less that 50 Feet away from each other.
I connected my 5ghz verizon connection wirelessly to my EAX20 through the nighthawk app and it works great at first. I get 400-600mbps for about 30 minutes when connected to my PS5 through an eithernet cord to my extender. After that it disconnects from the Router and I have reboot my router and Extender to get it back working, and sometimes it will disconnect permanently and I have to reset my Extender to get it working again. Any suggestions? Thank you in advance.
