This did not work for me. I rolled back to the previous version of the driver and that failed as well. With the computer on, I held the power button down for one minute, the machine will turn off. After one minute, powered it back on and it worked. According to an article I found, this clears some internal memory and that is what resolves the problem. Not sure if I can put an external link in here but search on this and you will find it. "MediaTek MT7921 Wi-Fi 6 card not working after Windows 11 June update, but there're some workarounds".
This device cannot start. (Code 10) {Operation Failed} The requested operation was unsuccessful.Above is the error code. I already tried re-installing but that did NOT work. I also tried checking Windows Updates and the computer is up to date.
