My laptop has been generating missing flags, so I have logged on with it to update location, which still gives me unable to connect. Have followed troubleshooting steps without success, so have re-installed software, but still unable to connect. From advanced help, when using an administrator command prompt to use the gui, I get a message relating to sudo - this is a linux command, and yet this is a W10 device?? "Seems you don't have write permissions. Try running with sudo" Any help much appreciated.
