As of 2015, Time Warner Cable does not sell Internet modems. It advises customers to buy a new modem online from websites, such as Tigerdirect.com and Amazon.com, or at local stores such as Wal-Mart, Target and Best Buy.
Customers need to activate the modem after purchasing and connecting it. Before buying a modem, customers should determine their plan and download speed. Some of the plans Time Warner Cable offers include Everyday Low Price, Basic, Standard, Turbo and Extreme. Customers can then choose from some of the TWC-approved modems. There are also some unapproved modems that customers can activate for use.
