Problem with Usb wifi dongle in ryzen Hackintosh when sleeping

I have installed OpenCore 0.5.9 and Catalina 15.5 in a ryzen 2600 build with a Asrock B450m pro 4,

I have a Realtek 8821CU using the chris1111 usb wireless USB adapter, Everything works just fine, but the problem starts when the screen goes to sleep, when I wake the pc the wifi is still connected, but with super low speed, less than 1mbps.

when I restart the pc, the wifi works fine
