Indeed, your cable carrier could be charging you up to $10 a month for your modem, which comes out to about $120 a year. And how many years have you been renting that cable modem? Yep, it starts to add up.

Instead, save some cash and buy a cable modem of your own, like this one from TP-Link. Normally about $60 but on sale for $40, the TP-Link TC-7610 is compatible with most of the big U.S. cable carriers, including Comcast, Cox, Charter, Cablevision, Time Warner Cable, and Xfinity. Just plug the cable coming out of your wall into the TP-Link modem, connect the modem to your Wi-Fi router, then call your ISP to help you with the activation process. Last but not least, enjoy the savings.

In fact, you could be spending up to $10 a month to rent your cable modem. Doing the math, that adds up to $120 a year, every year. Ouch.

Rather spend that $120 on something else? All you need to do is return your carrier’s cable modem and buy your own. Cable modems can usually be had for less than $100, and Amazon is having a sale on this $40 Netgear cable modem. The Netgear CM400 is compatible with XFINITY, Time Warner Cable, Cox, Charter and Cablevision—and for 40 bucks, your new cable modem could pay for itself in just four months.
