Want to Upgrade my Comcast Modem

[trchilson]

I'm looking to upgrade my SB-5100 Motorola Cable modem that I now rent from Comcast. My main objective is to increase my internet performance.

You could try a modem that has docsis 3 support but if comcast is only using docsis 2 in your area the new modem will just revert back to docsis 2.

Modems are pretty stupid they either work or they don't.
