Cannot connect to the internet

MAC address on a HP Pavilion dv7 laptop
where is it located?

David-
The problem is that the MAC address for your old computer is still in the Comcast database as the "authorized" computer for your service. When you replaced your computer, the cable modem sees a different MAC address, and is considered "not authorized".

Contact Comcast and notify them that you need to update your service with your new computer's MAC address. They will connect to your cable modem via telnet, grab the new MAC address and update their system. At that point, everything will work properly.

Good luck - hope this helps!

Are you running the setup disc provided by comcast to get your email setup?

If you are , you do not really need that disc as it provides useless and often outdated junk on the disc. You should be able to surf the internet by plugging in your Ethernet Cord into the laptop with no problem.

On the issue of the Comcast user name and password, this was originally used at the original configuration of the modem when it is wallgardened.

You can always call Comcast and have then activate the modem for you. You'll need the Mac address at the bottom of your modem to activate it over the phone.

Online Activation usually requires your customer account number. But since it looks like you do not have this data, you will need to call them directly.
