What to look for when you’re buying a modem?

Having a modem that supports phone services can be great because you can combine more features in the same device.

However, you should build a list of priorities and checklist because you don’t want to have any regrets after the purchase. Here are some things to consider.

Look for the service provider requirements

The most important aspect is to match the device with your service provider’s requirements.

A lot of modems, as you can see from our list, are not compatible with all the providers so ignoring that information can get you a useless device.

You should also match your data transfer speed with that of the modem. It’s useless to get a high-speed modem if you only have a 400 Mbps plan.

Having a high data plan and a slow modem is even worse because you won’t be able to benefit from your investment.

Check the functionalities of the modem

Some modems have a built-in router with more Ethernet ports and Wireless hotspot, others just give you a LAN port to connect your wireless router.

If you already have a good router, you won’t need more than the basic features from your modem but if you don’t, getting a modem with router capabilities can save you lots of money.

If you also want phone lines and VoIP services, check if your provider offers such services and look for a compatible modem, like the ones from our list.

Changing the modem

Buying the modem is not hard. Installing it, however, is a different story. Some providers offer you the necessary information, but others will consider it a professional service.

In any case, it’s not a job for anyone so it’s better to request assistance from your provider even if there could be a cost attached to this service. In the end, everyone must be happy, right?
