Cable companies want to keep modem rental fees a secret since it’s basically free money for them, but we refuse to play along. Unless you purchase your own cable modem, you have to pay a monthly fee forever to use the modem from your ISP. That’s right, forever. Imagine leasing a car but just having to pay the same amount every single month indefinitely. It’s ridiculous, and we’re putting a stop to it right now. The NETGEAR CM400 (8×4) DOCSIS 3.0 Cable Modem works with every major cable-based ISP such as Comcast, Time Warner Cable/Spectrum, Cox, and plenty more. It supports download speeds up to 343Mbps which is likely faster than your home internet service, and it’ll save you between $8 and $10 per month as soon as you activate it and return your old rented modem.

Speaking of saving, the modem costs $44.99 on Amazon but you’ll also find a $5 coupon right on the page, dropping the price to just $39.99.

Here are some highlights from the product page:

  • Support Cable Internet Service plans up to 100 Mbps. Separate router required for WiFi.
