Comcast and Time Warner Cable hike modem fees as much as 33%. Time to buy your own.

But the game has changed. Consider the yearly fees: Time Warner Cable’s rental fee is now $96. Comcast’s rental is now $120.

If you buy an Arris SB6121 modem, it’ll pay for itself in less than a year. If you buy the faster Arris SBG6580 (modems don’t have sexy or memorable names), it’ll pay for itself in just over a year.
