Buying Guide To Purchase Modem Of Your Choice

With the number of available devices, it’s getting difficult to differentiate which one is best. To put your hands down on the right one, we came up with some points that you should keep in your mind during a modem selection.

Modem or Modem-Router Combo

First, you must determine whether you go for a modem or a modem-router combo. Indeed, a combo device can save you from considerable expenses. Plus, it’s a good step if you plan to upgrade your massive networking set-up. But if you already have a router and modem is the only equipment to fulfill your requirement, go for it. It’s super easy to install and can work with any type of router by connecting it with the port.

DOCSIS Version

It’s crucial to figure out which DOCSIS technology a modem is operating on. Because if you require a gadget for your office or at an industrial level, then 3.0 technology will give you a hard time. So, it’s better to operate with DOCSIS 3.1, which makes the modem future-proofed.

Best DOCSIS 3.1 Powered Modems


Having a single port in the modem can serve the purpose. But it’s always a best practice to purchase a modem with multi-port connectivity to attach peripheral devices with it. A modem should possess at least a single gigabit Ethernet port to get 1Gbps speed from the broadband if you have.


Budget is always the most significant hurdle whenever we try to purchase something new. Several modems are out there to provide exceptional performance, but they are a bit expensive. Still, you can purchase a device with the DOCSIS version 3.1 if you are ok with the minimum speed efficiency.
