Thanks for your willingness to help, computuerbob. I am not sure what you mean by "go to system settings". Within the Menu, I have Places, System, and Applications. Within System I have Software Manager, Package Manager, Control Center, Terminal, Lock Screen, Logout, and Quit. When I go to Applications and click on Preferences I get a number of things to click on way over on the right. One of them is Network Connections, but when I click on this, I get the brief appearance of a not-quite-rendered dialog box, rather than a fully rendered one that would remain on screen and give me the opportunity to configure and run VPN as well as to manage my wifi connection.
