Introduction .


For this small workshop, you will need at least one ethernet cable and, of course, a second router, regardless of the brand.

We present you with two ways to connect your devices with a long cable between your two routers or, even better, wireless.

Alternatively, you can use to catch CPL. Please note that some internet service providers such as Orange or SFR in offer from 69 €.

The IP address of the router .


Before you begin, you must learn to know your router. Two information are very important : his channel — a channel number corresponds to a transmit frequency and its protocol of security (WEP or WPA are the most common).

On any Windows PC, go to control Panel and double-click on Network or Network and Internet.

On Windows XP, right-click on the network connection that is used for the connection to your router (Wi-Fi or Ethernet) and choose Status, then Support.

A window opens showing you the configuration of your network.

On Vista, Windows 7, 8, and 10, go to control Panel → Network and Internet → Network and sharing Center → Local Area connection (right).

Right-click the appropriate connection, click on the State of the media, and then Details.

This window will display your default gateway (link between the local network and internet for example) and your computer’s IP address (identification number).

Write down the number of your gateway.

Connect to the router .


Now, open an internet browser and enter in the URL bar, your number gateway. Press Enter.

The interface of your router is displayed.
For detailed explanations, see the article Access the interface of your router.

If your user name and password are requested, enter the.

If you do not know, you will find it under the router itself. If not, do an internet search on the model of your router.

Settings Wi-Fi .


Since the same configuration screen, take a look at the settings of the Wi-Fi. These are entered automatically by the DHCP Protocol (dynamic host configuration). This protocol configures automatically IP settings.

In our example, the Wi-Fi network (SSID) of our router is a Belkin, its channel is 6, and its security protocol is WEP.

Note somewhere your security protocol because you are going to set up your old router with the same protocol.

Finally, log out by clicking the logout option.

Restoration .


At present, to take care of your second router. It must be restored to factory settings for a go “to nine”.

Connect your router to a power outlet. .
Using a pin, press and hold for a few seconds on the button Reset, a small hole located on the back of your router..
Then, release. The flashing of the lights is normal, it indicates that your router is recovery..

On the second router .


With an ethernet cable, connect your 2th router to a PC that is not connected to your Internet network.

To do so, keep off your main router time to configure the router as secondary.

Reconnect and repeat the first two steps, until the configuration screen opens. In our tutorial, we have used a D-Link router.

Note that if you have only a single computer, you should disconnect temporarily from your network.

Match the settings .


Skip the configuration wizard and go to the tab Wireless Setup (Adjust Parameters), to the left.

Check the box Enable Wireless (Enable wireless)..
Change the name of the wireless network for it to be the same as the first router (avoid private information, because this network will be visible to all)..
Select a channel far enough away from the 6, which is reserved for the main router..
Select the same security protocol as the main router..
Enter the same password as the main router..
Save your changes by clicking on Save settingsat the bottom of the page..

The IP address .


At present, he is to give an IP address “fixed” your router’s secondary, so that it is recognized by the principal and they can work together.

To do so, always from the configuration wizard :

Go to the LAN tab and assign an IP address, almost similar to that of the primary router.
If, for example, the IP address of the primary router is, you can then assign the router a secondary address
See this address as you will need to connect to it.

Note that the DHCP protocol can generate an address automatically, it will be in this case a range between and

We recommend that you deactivate this option by unchecking the box Enable DHCP Server..
Save your changes by clicking on Save settingsat the bottom of the page..

Once this is done, you will need to restart your router and access it using its new IP address in the URL bar.

Connection .


Now, you’re ready to connect everything.

The ideal would be to connect the 2 routers with a long network cable, but to prevent you from getting tangled up in cables, the ideal would be to have a plug CPL (Current Holder Online).

These enclosures are connected as an electrical outlet and are equipped with outputs Ethernet, you can connect your computer, game consoles, routers, or box.

Both routers and turned on, test your network.

Please bring your smartphone, tablet, or laptop and check the signal strength.

Here, you are able to extend the reach of your Wi-Fi network and put in place a second internet access point !

The any wireless .


It may be that your router unused have already the necessary features to optimize your Wi-Fi network. In which case, you do not need ethernet cables or adapter.

We can not list all the routers to bridge between different connections or who can play the role of a repeater. However, the majority of models are doing it, so don’t worry.

The WDS (Wireless Distribution System) is the most interesting function of the routers, this system allows for the interconnection of multiple access points wireless Wi-Fi.

When you configure a router with WDS, you only need to select the connection type, SSID, band network (Network band) and security type.

Customize the firmware of the router (firmware) .


For routers without WDS, you’ll have to install a firmware such as DD-WRT, Open-WRT or Tomato.

If you are not comfortable with the technology, do not venture.

Install DD-WRT may seem as simple as the installation of a software but this is not the case. In fact, if you do not do this correctly, your router won’t end up in your closet but in the trash !

First of all, it must be compatible with DD-WRT, Open-WRT or Tomato. To find out, do an internet search.

If compatibility there is, carefully follow the information related to the router, the instruction manual and its safety precautions.
