Your solution for poor internet connection in a small business lies in getting a good modem. A modem is a short form of modulator-demodulator. It is a device that converts data in a format that can be transmitted from one device to another.

Choosing the best modem for your business

Getting the best modem is having your internet challenges half solved. With a good modem, you can choose your best service providers anytime and have your internet up and running.

Buying your own modem will save on modem rental fees from your internet service providers. This way you reduce the monthly costs for your business and also save on costs in the long run.

The best modem has the following traits:

DOCSIS Standard

The DOCSIS standard is the definition of the specifications for your modem. The best modems for a small office should either have DOCSIS 3.0 or DOCSIS 3.1 standards.

DOCSIS 3.0 modems will serve most small businesses since they support internet speed tiers except the gigabit tier. The modems are cheaper and most have gigabit Ethernet ports.

DOCSIS 3.1 modems, on the other hand, support even Gigabit internet plans. They are however most of the time more expensive than DOCSIS 3.0 modems. For small businesses, it may be an overinvestment.

Ethernet ports

Getting a small business modem with one or more gigabit Ethernet ports is recommended. This will enable you to connect the modem to the router for fast speeds. Moreover, in the case of more than one Ethernet port, you can connect to other devices such as PCs, streaming devices, printers, and others.

There are several modems reviewed here that have one or more gigabit Ethernet ports.


The best modem for your business should be compatible with most ISP cables. You should also be able to connect to other devices such as your PC and gaming devices. Connecting to any type of router should also be simple.

Several modem routers are compatible with Spectrum, cox, Comcast Xfinity internet, and other internet service providers.


The design of your modem will determine where to place it and have the best connection. A good modem should be compact and easy to spot. While in use, you should be able to see the performance and be notified of any challenges as they arise.

The design will help to fit the modem in a place where you can easily place your router if you are picking separate modems and routers.


A low-speed modem will mean low internet speed and vice versa. When buying a modem, ensure you get one that has the highest internet speed. The download, upload, and overall performance speed should be great. You will, however, face business management challenges.

The speed for your modem must be able to match the speed that you have subscribed for from your internet service provider.


A small business will need an affordable modem. However, when checking on the price, you should be cautious to avoid getting a substandard modem to keep disappointing and failing your business.  Do not compromise the quality with the price of your router.
