Thank you for the helpful replies. I do not have access to the laptop at present, but will try your suggestions later. Could you clarify whether I should run the various terminal commands before I attempt an 'Install Upgrades' - that is on a system that has working WiFi but is un-upgraded, or after I have done so, which will probably knock out WiFi access. I guess the simplest thing is run the commands before and after the upgrade.
Thanks
