  1. I just bought mine at Dontleaseyourmodem.com. It was the cheapest I could find online and they even offer free shipping, warranty, and even set up instructions specific to Comcast! It was easy to set up and now I am well on my way to escaping the dreaded lease fee and will break even and save even more in no time.

      Hi Joe,

      For your security, we removed your phone number from your post.

      It’s probably best you contact Time Warner for best guidance: https://www.timewarnercable.com/en/support/contact-us.html
