Note the following policy from Charter: Effective July 26, 2012 For new Internet Customers and customers switching to our New Package Pricing, we will no longer allow customer-owned modems on our network. In order to provide our customers powerful and reliable Internet service at a great value, we will provide modems included in Internet pricing under our New Package Pricing. This notice can be found here at the top of the page: Charter Policy on Customer Owned Modems for New Internet Customers and Customers Switching to New Package Pricing

If you're paying $7 a month to rent a modem from Charter, that's $84 a year or $420 over 5 years. You can buy a new one for less than that. There are used ones that will pay for themselves in less than 3 months.
