I tried the template but it didn't work for me it just kept disconnecting and after a few hours of research I came across the information below taken from:
http://www.dslreports.com/faq/8199Generally you will need to either use CHAP or PAP authentication. In some cases ISP requires both type of authentication. Following is how to set both up.
router(config-if)#ppp authentication chap pap callin
router(config-if)#ppp chap hostname ispusername
You want to make sure that username is whatever your ISP requires. Some ISP like the full e-mail address and some just need the username. You may receive a letter or email regarding this info. Consult your ISP if you are unsure. Following is the setup.
router(config-if)#ppp chap password isppassword
router(config-if)#ppp pap sent-username ispusername password isppassword
As you can see, with PAP as opposed to chap you input your username and password all at once in one command.
In some routers running newer IOS image, you may need to enter the password as it is (clear text) or encrypted. When you need to enter them as clear text, then you need to type in 0 (zero) then the password to indicate the password you are about to enter is in clear-text format. Similarly, you need to type in 7 (seven) followed by the password to indicate the password you are about to enter is in encrypted format.
