My router came from my cable provider (comcast) it has WiFi built into it. I remember changing the password they sent me, and I still remember what I changed it to. The router has an xfinity label on it and on the back it has a SMC model label on it. I am trying to connect my tv to the WiFi however when I am prompted to enter the security code password I get an unable to connect reply. Please advise as to how to get my password security code. Also, please remember that I can not assist in providing a user name or password. A Comcast technician advised me or tried to persuade me to purchase their live tech support. I already give them enough money and felt terrible that they wouldn't help without me first paying them money.
