What is a modem/ what does a modem do?

What is a modem? Do i need a modem and router

A modem only connects a single device to the internet. This device helps to bring the internet to your home using a public IP address. In most cases, the modem is connected to a coax cable from an internet service provider (ISP) to provide internet.

The modem thus picks the ISP signals and changes them to signals that the wide-area network (WAN) devices in your home can use. It also picks signals from your devices and translates them to signals that the ISP can transmit.

There are several brands of modems that can be used for different internet speeds. To choose a modem, you have to consider the following:

  • The internet speed plans that you have subscribed for: There are several modems in the market. The different modems work best at different internet speeds. Different ISPs give a list of recommended modems for different speeds. The service providers include Spectrum (Charter), Xfinity(Comcast) Consolidated communications, CenturyLink, AT&T, and Cable one among others. Internet speeds depend on the DOCSIS, Channels, and other specifications of the modem.
  • The ISP compatibility: The different ISP give different lists of recommended products also depending on the compatibility. Before picking any modem it is good to check if it is compatible with your ISP.
  • Security of your data and parental control: There are several hackers, viruses, and malware that are available on the internet today. To get a modem that will protect your data should be one of the highest priorities. Different modems provide different levels of protection. In addition, parental control of the materials being observed by your children should also be a high priority.
  • The design: There are different modems with different designs. For aesthetic and space considerations, it is good to check the modem design.
  • Do you want a modem-router combo or separate: There are several pros and cons of a modem-router combo. We will discuss these below.

How to replace the rental modem router with your own modem router

What is a router/ what does a router do?

What is a router? Do i need a modem and router?

It is a device that connects your devices to the modem and each other. The router thus connects the modem to internet-enabled devices such as laptops, televisions, printers, phones, tablets, and other smart devices.

A router assigns a local IP address to all the devices on the LAN. This enables the router to sort out the information and lead it to the required device.

The router uses either an Ethernet cable or Wi-Fi signals to connect your devices to the internet. This means that the router creates a local area network (LAN) within your space. This enables data sharing with other devices in the house like a printer, the router, or other devices.

The router can sort all the information that is transmitted within your devices and lead them to the intended destination. This is important if, for example, you need to print a document from your laptop in a printer located in your house/ office.

In some cases, you do not need a modem for the router to work. The LAN can connect all the devices in the cycle. This way you can send information from one device to another without the use of the internet.

A good router is supposed to create a firewall to prevent your information from being stolen, destroyed, or altered. The firewall thus prevents most of the security breaches in your network. Most of the routers available in the market today are also able to handle parental controls.

A guide on how to choose a router:

  • Your internet service providers: There are some routers that are not recommended for some ISP networks. It is always important to find out if the device is recommended or certified for an ISP.
  • Internet speeds available: Different routers provide different levels of internet speeds in your home. Therefore, before buying a router, check the speed of the internet that the device is recommended for.
  • Range of coverage: A router is able to provide the internet via Ethernet cable and Wi-Fi. For Wi-Fi coverage, it is good to check the area that the router will cover with Wi-Fi signals. Some people will thus choose a mesh network or other long-range routers.
  • The number of devices: Different routers connect to a number of devices on Wi-Fi either through Ethernet ports or through Wi-Fi. Our digital homes and offices currently have so many smart devices. Therefore, it is great for you to check the number of devices that a router can support before buying it.
  • The number of Ethernet ports: Some of the devices available at home can only be connected to the internet via the Ethernet ports. These may include printers, older PCs, and other devices. If you have several of these devices, it is also good to consider the number of these ports thus getting the best-wired router for your home or office.
  • Buying a modem/ router combo: If you have no modem in your house, you may consider buying a combo. But what are the pros and cons of a modem/ router combo?
  • Price: The price of different routers varies depending on the other factors. The price should be the last thing to consider when buying a router since there is some variety to choose from.

Modem router combo FAQs

Should I buy a Docsis 3.0 or 3.1 modem?

The modem you are buying depends on the internet plan you have now or are planning to have in the future. If you have a gigabit internet plan, you need to get a DOCSIS 3.1 modem. If you have a lower internet speed plan, we recommend getting a DOCSIS 3.0 modem.

Does it matter what modem router I use?

Yes, it does matter the modem router you use since compatibility, technology, and internet speed determine the modem router chosen. If you have a gigabit plan, you need to get a Gigabit compatible (Docsis 3.1) modem router. Thus, ensure your modem router supports the internet plan you have.

Is it better to get a modem router combo or separate?

Both options have advantages and disadvantages. A modem router combo serves all your networking needs in one device thus reducing the messes and also is easy to brainstorm- thus is easier to set up and use overall. Moreover, you are assured of compatibility unlike getting two devices that may not be compatible. However, they are more expensive, and in case of damage to the device, you have to replace the whole of it.

Are modems and routers the same thing?

No, modems and routers are not the same thing but both work together to enable internet provision to our homes or offices.  A modem translates ISP signals into signals that your home devices including a router can use. The router on the other hand creates a wireless or wired network that can connect multiple devices to the internet and to each other. Therefore, to connect to the router on the modem you have to use an Ethernet cable but on the router, you can use WiFi or ethernet connections to access the internet.
