    I am trying to get the free modem upgrade. I am unable to get to any other site to order it. Last week I called and spoke with someone about sending one and today I received a phone message telling me to request one on the site upgrade but I have not been able to do so.

    Numerous times I have received calls to upgrade my modem, I registered once for the modem and never received it. It appears that I am not alone in that respect. In speaking with my local Comcast vender, no one seems to be aware of this upgrade technic. What is this really about? If there is an upgrade availability, I would love to have it because of so many issues with the Xfinity Internet service. It really sucks!

    You said go to the website device upgrade and sign in but there is nowhere to sign.
    I have never used my Comcast login or password anyway so I guess this will never happen.
    Thanx for making this so complicated.

    I have tried to get this web site to send my new modem. i also called the main office and she told me I could pick it up at our Comcast here in Gadsden for free. I went there and they said it would cost 15.00 dollars to get it there. As much as I pay them, that was an internet is lousy. I had ordered it long ago and never heard anything about it. just send it or I will go elsewhere.
