Our Take

Best for: Cable internet users with plans up to 600 Mbps who need a reliable modem.

The Motorola MB7621 is a straight-up cable modem that has been doing the job for years. With 24x8 channel bonding, it handles typical cable internet plans up to 600 Mbps without breaking a sweat. It connects to your ISP via coax and to your router or PC via a single gigabit Ethernet port. Setup is simple: plug it in, call your provider, and you are online in minutes. The build is basic but dependable, and the lack of built-in Wi-Fi is actually a plus if you already own a good router. The only real limitation is that it has just one Ethernet port, so you cannot connect multiple devices directly without a switch or router. 0 is older tech, so if you ever jump to gigabit fiber or cable, this modem will cap out. 99, this is a genuinely smart buy for anyone who wants to stop renting a modem from their ISP. The savings over a year of rental fees pay for the modem several times over. If your plan is under 600 Mbps and you just need a rock-solid modem, this is one of the best value picks.

Price Analysis

The current price of $49.99 is a 72% discount from the original $179.99, putting it at a level that easily beats most rental fees. This is the kind of price that makes buying a worthwhile investment from day one.
