If you want to increase the physical area of ​​your network, but also the number of simultaneous Internet connections, then you need to connect two routers together. Locally, the easiest way to connect two routers is to use an Ethernet cable, although it is also possible to establish a wireless link.

Steps

Method 1 of 2: Connect two routers with an Ethernet cable

Connect Two Routers Step 1

Step 1. Determine which router will serve as the primary router

This will be the router that will be connected to the modem that gives you access to the Internet. In general, and it makes sense, you should take the newer and better performing of the two.

As long as the two routers are strictly identical, take either of the two as the primary router

Step 2. Determine which router will serve as the secondary router

It is the one that will allow you to extend your network. You will choose the less efficient of the two, often the older one.

This router will control the local network in the case of a LAN / WAN type network (see step 4)

Step 3. Place your two routers near your computer

During the initialization process, it is good to have them both handy to avoid having to run around. You will install them later in their final place.

Connect Two Routers Step 4

Step 4. Choose the connection type

You can choose between a LAN / LAN (two local networks) or LAN / WAN (one local network and one wide area network) connection. For these two connections, you can use an Ethernet cable. These two new networks do not have the same functionality.

  • With a LAN / LAN connection, you extend the surface area of ​​your wireless network. Such a connection allows you, as you are entirely local, to share files between all the devices (computers, smartphones, tablets) on the network.
  • With a LAN / WAN connection, you create a second network inside the main network, which allows you to place restrictions on all devices on the second network. Such a connection does not allow file sharing.

Step 5. Prepare for the configuration of the main router

Connect it to the modem with an Ethernet cable, then your computer to the router with another Ethernet cable.

  • With Mac computers no longer having an Ethernet port, use an Ethernet to USB-C adapter (also known as the terrible Thunderbolt 3) to get around the difficulty.
  • For Windows PCs that do not have more Ethernet ports, you will need an Ethernet to USB adapter.

Step 6. Configure your primary router

Since this router serves as the entry point to the Internet, configure it as if it were the only router on the network.

  • To access your router's configuration page, you must enter its IP address in the search bar of your Internet browser.
  • This configuration page varies from router manufacturer to router. If you cannot find a particular setting, it is best to consult the paper or online documentation established by the manufacturer.

Step 7. Change the DHCP protocol settings

If you are setting up a LAN / WAN network, go to the configuration page of the main router and in the DHCP section, provide a range of addresses, for example 192.168.1.2 and 192.168.1.50.

  • If you are setting up a LAN / LAN network, you can leave the DHCP protocol settings already present.
  • Unplug your computer from the router when setup is complete.

Step 8. Configure the second router

Now connect the second router to your computer (the first having been unplugged): the configuration is simple.

  • Open the secondary router configuration page.
  • Change its IP address to match that of the first router. To do this, copy the selected IP address and modify the penultimate number. Thus, 192.168.1.1 will become 192.168.2.1).

    If you are creating a LAN / WAN, change the WAN IP address of the secondary router to be 192.168.1.51

  • Make sure the subnet mask number matches that of the primary router.
  • If the UPnP option is enabled on the second router, disable it.

Step 9. Configure the DHCP server on the secondary router

If you are setting up a LAN / LAN network, DHCP must be disabled on the secondary router. On the other hand, with a LAN / WAN link, the DHCP protocol of the secondary router must be able to assign dynamic IP addresses between 192.168.2.2 and 192.168.2.50.

Step 10. Change the wireless channel

If the two routers each operate on a wireless link, you will need to set up the channels so that there is no interference between the two links. Usually, the primary router is assigned any channel between 1 and 6, while the secondary router uses channel 11.

Connect Two Routers Step 11

Step 11. Place your routers in the locations provided

Both routers are configured, you can install them wherever you want. Remember, however, that you will need to connect them with an Ethernet cable.

  • Note that an Ethernet cable can easily be passed through a wall.
  • For obvious practical reasons, the primary router is most often placed near the modem.
Connect Two Routers Step 12

Step 12. Plug in the two routers

Take your Ethernet cable, plug one end into the LAN port of the primary router and the other end into the LAN port of the second router: it's that easy!

If you are setting up a LAN / WAN network, the second end will be connected to the WAN port (also called “Internet port”) of the secondary router

Method 2 of 2: Connect two routers wirelessly

Connect Two Routers Step 13

Step 1. See if your hardware is compatible

While most wireless routers are capable of relaying a wireless signal, thereby increasing the coverage of a primary router, wired routers do not necessarily have this functionality, which will not allow you to create a new network within. even from the network managed by the primary router.

  • In order to be able to create a wireless network within the primary network itself, the secondary router must be able to act as a repeater or operate in mode. Bridge.
  • By reading the router documentation (paper or online), you will quickly know if yours can work in mode. Bridge.

Step 2. Place the two routers near your computer

So you will have both devices handy and the modem is not far either. Once the configurations are complete, you will install the routers later in their final place.

Connect Two Routers Step 15

Step 3. Prepare for the configuration of the main router

Connect it to the modem with an Ethernet cable, then your computer to the router with another Ethernet cable.

  • With Apple brand computers no longer having an Ethernet port, use an Ethernet to USB-C adapter (also known as Thunderbolt 3) to get around the difficulty.
  • On Windows PCs that do not have an Ethernet port, you will need to use an Ethernet to USB adapter.
Connect Two Routers Step 16

Step 4. Configure your primary router

Since this is the router that gives access to the Internet, set it up as if it were the only router in play.

  • To access the router's configuration page, enter its IP address in the search bar of an Internet browser.
  • This configuration page varies from manufacturer to manufacturer. If you cannot find a particular setting, it is best to consult the paper or online documentation established by the manufacturer.
Connect Two Routers Step 17

Step 5. Open the secondary router configuration page

Using an Ethernet cable, connect the secondary router to your computer, then open its configuration page. For this operation, you do not need to be connected to the modem. In this configuration page, see where is the access to Internet configuration, page which can also be called Wireless (wireless).

Connect Two Routers Step 18

Step 6. Activate Bridge mode

On the wireless connection setup page, activate the wireless mode. Bridge Mode (Bridge) Where Repeater Mode (Repeater). These two modes are always found in a menu which is called, depending on the brand, Network Mode (Network mode), Wireless Mode (Wireless mode) Where Connection Type (Connection type). If you cannot find any of these menus, chances are the router does not support wireless signal repetition. In this case, you will still have the option of using the Ethernet link.

Connect Two Routers Step 19

Step 7. Change the IP address of the secondary router

Type an IP address that must be in the address range of the primary router. For example, if the IP address of the primary router is 192.168.1.1, enter, for example, 192.168.1.50, if you have provided in the DHCP section of the primary router 49 addresses.

Check that the subnet mask address of the second router is exactly the same as the subnet mask address of the primary router

Connect Two Routers Step 20

Step 8. Give your second router an unambiguous name

This way, if you have a problem, you will be able to find out which network you are on.

  • Suppose you called your router Primary… Primary (admittedly, this is not very original!), You could call the second router, Office: thus, no ambiguity!
  • Also check the network security. In this regard, the best is to use a WPA2 key for the two routers, it goes without saying that they will both use the same password.
Connect Two Routers Step 21

Step 9. Place the secondary router in the correct location

Once the latter is configured, you can install it wherever you want, it will repeat the signal received from the first router. If you want it to work well, it needs to receive at least 50% of the original signal i.e. from the primary router.

To have the least possible attenuation of the signal between the two routers, it is of course preferable that there are no physical obstacles between them, such as a wall or a piece of furniture, nor a poorly insulated power line (risk of parasites)
