Easy – buy your own equipment. It pays for itself in months!

Updated: we’ve updated this post to include our recommendations for three tiers of Comcast-compatible modems.

Thousands of users are unknowingly wasting money through Comcast by paying for an unnecessary monthly modem rental. Recently, Comcast raised their monthly modem rentals from $8 to $10 a month. Many Comcast customers pay this monthly fee for their modem, because they feel as if it is the easiest and cheapest choice. However, with a little research, it becomes obvious that buying your own modem is a much better deal.

While the technologically clueless may argue that buying a modem is complicated, it is not complicated at all if you have the right information in your hands. is probably your best bet for finding a great deal on a modem. Any DOCSIS 3.0 modem you find will be up to date and should be easily compatible to your Comcast service. These modems sell for around $60-$100. If you plan on being a Comcast member for longer than a maximum of ten months, than buying your modem will save you money.

The difference in the $40 range between compatible modems will depend on how up to date it is. While you can find a compatible modem for Comcast for as low as fifty or sixty dollars, the $100 modem will more than likely allow you to have faster connection if you ever decide to upgrade in the future.

If you were previously renting a modem/router combo, you may need to buy your own router as well. In our office, we use the Google Wifi system which is amazing and beautiful and works flawlessly—it lets you monitor usage and set up guest networks and all sorts of neat tricks—but it’s expensive. If you’re just looking for something to get the job done at below 300Mbps, the TP-Link N300 is a solid, popular choice in the under $30 range.

In order to make sure you are buying a compatible modem, check Comcast’s website for a list of compatible models. You can find this information at
