In order for a router to function properly, it must be connected to a modem.
A modem is a device that connects to your internet service provider (ISP) and allows you to access the internet. The router, on the other hand, is a device that allows multiple devices on your home network to connect to the internet through the modem.
Why the Router Needs to be Connected to the Modem
The router is what allows multiple devices on your home network to connect to the internet at the same time.
Without a router, only one device would be able to connect to the internet at a time.
The router acts as a middleman between the modem and the devices on your home network, allowing multiple devices to connect to the internet simultaneously.
In addition to allowing multiple devices to connect to the internet at the same time, the router also provides security for your home network.
The router creates a firewall that protects your home network from external threats and can also provide additional security features such as parental controls.

How to Connect a Router to a Modem
Connecting a router to a modem is a relatively simple process.
First, locate the Ethernet port on the back of your modem and plug one end of an Ethernet cable into it. Then, locate the WAN (Wide Area Network) or internet port on the back of your router and plug the other end of the Ethernet cable into it.
Once the cable is plugged in, turn on your modem and router and wait for them to connect to your internet service provider.
This process may take a few minutes. Once the modem and router are connected, your devices should be able to connect to the internet through the router.
It’s important to note that some modem/router combos may have a different process for connecting.
If you’re unsure how to connect your router to your modem, refer to the instruction manual that came with your devices or contact your internet service provider for assistance.
Can A Router Work Without A Modem?
No, a router cannot work without a modem. A modem is a device that connects to your internet service provider (ISP) and allows you to access the internet.
The router, on the other hand, is a device that allows multiple devices on your home network to connect to the internet through the modem.
Without a modem, the router would not be able to connect to the internet and therefore would not be able to provide internet access to the devices on your home network. In order for a router to function properly, it must be connected to a modem.

Can You Use Any Modem With A Router?
In general, you can use any modem with any router, as long as the modem is compatible with the internet service you are using and the router is compatible with the type of network you are setting up.
When choosing a modem, it’s important to make sure that it is compatible with your internet service provider (ISP) and the type of internet service you are using (e.g. cable, DSL, satellite, etc.).
Most ISPs will provide a list of approved modems that are compatible with their service. If you’re unsure which modem to use, you can contact your ISP for assistance.
As for routers, you can use any router that is compatible with the type of network you are setting up (e.g. wireless, wired, etc.).
Most routers are compatible with multiple types of networks, so you should be able to use any router with your modem, as long as it is compatible with your internet service.
It’s also important to note that some internet service providers may require you to use a specific modem or router in order to access their service.
In these cases, you may need to use the specific modem or router provided by your ISP in order to connect to the internet. If you’re unsure whether you need to use a specific modem or router, you can contact your ISP for assistance.
Final Thoughts
In conclusion, the router must be connected to the modem in order for it to function properly and provide internet access to the devices on your home network.
The router acts as a middleman between the modem and the devices on your home network, allowing multiple devices to connect to the internet simultaneously and providing security for your home network.
