I do appreciate the advice. None of your IP addresses worked, but the "ipconfig" command gives my "Default Gateway" IP address, which takes me to the ATT U-verse Admin page. There are multiple tabs within tabs there, so I'll have to explore and find the page with the encryption settings, if that's where they are.
Not experiencing any problems. Just want to change over to the most modern/secure method if I can. Thanks.
