rtl8811au errors on make after upgrade to 21.04

I am trying to get my netgear a6100 working after upgrade to 21.04. Getting this on the make, need some help installing this again, as it was installed on 20.04 and worked. Thanks.

Please run the terminal command:

lsusb

Is your device 0846:9052? If so, try this driver: https://github.com/aircrack-ng/rtl8812au

Post back if you need a step-by-step.

If that is not your device, post it and we'll proceed.

After a reboot, does your wireless work?

Also, I suggest that you use the dkms process as described in the README. That way, you won't need to reinstall the driver after every kernel update.

Yes, solved.
