Wifi disconnects occasionally

Realtek 8812Bu adapter (Realtek 88x2bu Ac 1200 MBPS)
Wifi cuts out occasionally even though power management is passive.
How can I solve this?
The driver comes installed. I am using Kernel 6.8 with Zorin OS.

Are you sure it does occasionally and not as scheduled? Because even my network disconnects briefly after exactly 4 hours of active connection but this “isn't” a problem, it's a provider choice. Some other providers disconnect the network after a different time. If you see that this disconnection always happens after the same time then it's as I said. Because otherwise you'd remember if you set a power-save feature or bandwidth limit that can explain this disconnection. I was always confused on what was causing these short disconnections until in a chat I had some interesting info that confirmed my suspicions, and then anyway some simple checks every exactly 4 hours from my pocket modem management page proved it.
