Routers often come with built-in security features like firewalls, parental controls, and encryption to protect your devices and data from cyber threats.
Combining Modems and Routers: The Best of Both Worlds
While modems and routers are two separate devices, they can be combined into a single device, known as a modem-router combo. These devices offer the convenience of having both a modem and router in one unit.
Modem-router combos can be beneficial in several ways:
Space-Saving Design: Combining both devices into one unit saves space and reduces clutter.
Easy Setup: Modem-router combos often come with simplified setup processes, making it easier to get online quickly.
Cost-Effective: Buying a single device can be more cost-effective than purchasing separate modem and router devices.
However, it’s essential to note that modem-router combos can have limitations. For example, they may not offer the same level of customization as separate devices, and upgrading individual components can be more challenging.
Conclusion: Can You Get WiFi from a Modem?
In conclusion, the answer to the question “can you get WiFi from a modem” is a resounding no. Modems are designed to establish a connection to the internet via a wired connection, while WiFi connectivity requires a router to broadcast a wireless signal.
While modem-router combos can offer convenience, it’s essential to understand the roles of both devices in providing reliable internet connectivity. By separating the two devices, you can choose the best modem for your internet service provider and select a router that meets your specific WiFi needs.
Remember, when it comes to internet connectivity, having the right devices and understanding their roles is crucial for a seamless online experience.

Is a modem and router the same thing?
A modem and router are two separate devices that work together to provide internet access. A modem connects to the internet using a physical connection, such as a coaxial cable or fiber optic cable, and converts the internet signal into a digital signal that can be understood by devices on your network. A router, on the other hand, takes the digital signal from the modem and broadcasts it as a wireless signal, allowing devices to connect to the internet via WiFi.
In other words, the modem is responsible for bringing the internet into your home or office, while the router is responsible for distributing the internet signal to your devices. While some devices combine the functions of a modem and router into one device, known as a gateway, they are typically separate devices that need to be purchased and configured separately.
Can you get WiFi from a modem?
No, you cannot get WiFi from a modem. Modems do not have the capability to broadcast a wireless signal, which means they cannot provide WiFi connectivity to devices. Modems are designed to connect to the internet using a physical connection and convert the internet signal into a digital signal that can be understood by devices on your network.
To get WiFi, you need a router, which takes the digital signal from the modem and broadcasts it as a wireless signal. The router is what allows devices to connect to the internet via WiFi. Without a router, you would need to connect devices to the modem using Ethernet cables, which would limit the mobility and flexibility of your devices.
What is the purpose of a modem?
The primary purpose of a modem is to connect to the internet using a physical connection, such as a coaxial cable or fiber optic cable. The modem converts the internet signal from the physical connection into a digital signal that can be understood by devices on your network. This allows devices to access the internet and communicate with other devices on the network.
The modem is responsible for establishing and maintaining the internet connection, including tasks such as authenticating with the internet service provider (ISP), negotiating the speed and quality of the connection, and managing data transmission and reception. In essence, the modem acts as a gateway to the internet, providing a pathway for devices to access the online world.
