How can i find the at&t security ket for my dsl

I have had AT&T high speed Internet for 2 years. Suddenly my laptop won't connect and is asking me for a security key? I don,t remember what that was when I first set up. How can I find it?

contact AT&T is the only advice we can really give you. we can't tell you how to get a password for any type of item.
