Rick,
That has done the trick as far as the wifi connection is concerned.
Should I follow the same procedure for the Realtec PCIe GBE Family Controller which, in Device Manager, has a yellow triangle with ! inside, against the " Realtec PCIe GBE Family Controller - VirtualBox Bridged Networking Driver Miniport" adapter?
Thanks very much for sticking with me and solving this issue, much appreciated.
All the best.
