dual boot – Weak and disconnecting wifi with RTL8821CE that is strong with windows

I have a 2 antenna wifi that gets a great signal on windows. On dual boot Ubuntu 20.04, it’s very weak, to the point that it starts disconnecting if kept on long enough. Any ideas of what could cause this? I tried setting wifi.powrsave = 2, turning off IPV6, and turned off power saving on windows startup.
