I tried every combination of options; Uncrypted password(PAP) Challenge Handshake, Microsoft CHAP Version 2, Automatically use my WIndows name and password, Extensible Authentication Protocol (EAP). All same result. Error code 800.
I am going to open a case with century link and see if they can see anything. Not sure what else to try, it worked fine and then all of a sudden it does not. We have made no changes to hardware or software on router or internal.
