Since a vast majority of people are still relying on the work-from-home opportunities due to COVID-19, our Wi-Fi networks are working overtime, doing much more than just allowing you to play games and stream your favorite shows and movies. Millions rely on these home Wi-Fi routers to stay connected, and they’re also connecting an expanding number of smart devices. For these Wi-Fi routers to work, we also are required to be subscribed to services like CenturyLink internet so that our online lives are never impacted.

When we’re stuck with simply a router and don’t know what to do with it, it’s natural to wonder what we can do about it and if is it possible for a Wi-Fi router to work without a modem? So let’s discuss the differences between the two and find out whether the Wi-fi router functions without a modem or not.


Routers are devices that are used to set up and manage home networks. They also serve as a connection point between gadgets and the internet at large. They typically have four LAN access points where devices can be plugged in, as well as one or more wireless networks to which devices can connect through Wi-Fi. As a result, routers generally feature antennas, whereas standalone modems do not.

The routers assign IP addresses to devices so that home networks may be managed more effectively. They provide a firewall and other additional security measures for the home network, ensuring that data does not arrive unregulated from the internet. Routers are an important component of any home network that connects various devices. If you only had a modem, you could only connect one device at a time, and only by cable. Routers allow additional devices to connect. They cannot, however, connect to the internet without modems unless they come with a built-in modem.


Modems transform the data that comes into your home via the internet into a form that devices can understand. Because the modems communicate with your internet services providers, any modem you choose must be compatible with all kinds of connections, for instance cable, DSL, fiber, and also with the ISP.

On the back of most modems is one Ethernet port that can be used to connect one device via LAN cable, but this is commonly utilized to connect to the router, which then provides four Ethernet ports as well as Wi-Fi access for improved connectivity.

Modems don’t set up or maintain home networks, and they don’t send out any Wi-Fi signals. They do nothing but decode data from the internet, which is then delivered to the router to be disseminated to the appropriate network device.

Is It Possible For A Wi-Fi Router To Work Without Modem?

A router can function without a modem. The router establishes a link between your devices before assigning each one an IP address. It also lets you share data from one device to another and stream movies from your phone to your smart TV.

However, it is not practical to deliver definitive data across large distances through an Ethernet connection. The information is sent in the form of signals that can only be decoded by a modem. Remember that WiFi and internet access are not the same thing, and they are not interchangeable.

Maintaining The Router

Routers are complex pieces of technology, and we can’t teach you everything you’ll need to know about them to solve every networking issue you’ll encounter. These troubleshooting and maintenance suggestions, on the other hand, should help you maintain your network functioning smoothly and safely.

  1. Change your password now and then. This includes the WPA2 or WPA3 passkey for connecting new devices to the router, as well as the administrative password for changing settings and installing firmware updates. The default passwords for each are normally posted on a label on the bottom of the router, and changing them lowers the danger of someone gaining access to your network.
  2. Rebooting the routers does assist them in functioning smoothly. Switch off or unplug your router if it keeps missing connections or you can’t connect to the Internet at all, wait 10 seconds, and then turn it back on.
  3. Make sure that your router’s firmware is always updated. Firmware upgrades can improve the speed of your router, introduce new capabilities, and, most importantly, fix security issues. Many newer routers will automatically install firmware updates, but others won’t so check your router’s manual for advice on how to check for and install updates.
  4. Correct placement of your router device is one of the most important things. A standalone router should be placed as close to the center of your home as feasible and out in the open, but all routers and satellites should be free of obstructions.
