As far as another option, you can buy your own modem and install it with the TM3402. You'll just have to call Cox to activate your new Internet modem..
I had the TM3402 as an all-in-one device for my services but it started fumbling with connectivity. I still had my previous DOCSIS 3.0 so as an interim solution, I installed it alongside the TM3402.

As long as your potential Internet modem is on the Cox Approved List, you should be good-to-go.
