The link you provided in the first reply proved invaluable as I was able to determine the exact module that is installed in the Macbook and what driver was required. From that I threw the problem at chatgpt who produced a script for me that automatically retained the correct driver during any future system updates. After installing the script, I applied all outstanding updates and after a reboot there was smiles all round. The WiFi was still operational. I will attempt to post the script(probably tomorrow) as you suggested. Thanks for your support.
