Things to prepare

To reuse the router as a WiFi repeater, the following should be prepared:

  • The Powerline adapter (the device that transmits the Internet through the home electrical system) does not have WiFI

  • Old router (802.11n or 802.11ac)
  • Ethernet wire
  • Extension cord (if any)

Create a new repeater

First, determine the current router’s IP address, broadcast channel and the type of security it uses.

1. Open Settings.

2. Click Network and Internet.

3. Click the link “Network and sharing center”.

4. Change the adapter settings.

Change adapter settings

5. Right click on the WiFi in use.

6. Click Status.

7. Click the button Details.

8. Make note of the primary router’s default gateway address.

Connect to the main router

To connect to an existing router, access it by entering the IP address or entering the address provided by the router manufacturer into the browser.

  • Asus –
  • Belkin – http://router
  • D-Link – http://mydlinkrouter.local
  • Linksys – http://myrouter.local
  • Netgear –
  • TP-Link – or

Enter your username and password. If you do not know this information, you can find it at the bottom of the router, search online or refer to the following articles:

  • Default password list of Linksys routers
  • List of default passwords of routers, Cisco switches
  • NETGEAR router default password list
  • List of D-Link routers default passwords

Check WiFi settings

At this step, we won’t change anything, just look for information about the WiFi settings to use in setting up the second router.

1. On the home page of the router you just visited, find the router name, channel and security type.

WiFi settings

2. Write down this information but do not change anything.

3. Sign out.

Reset old router

The first thing to do with an old router is to completely erase any stored data from the moment you started using it.

1. Power on the router.

2. Insert a paperclip or other small and thin object into the hole marked as “reset” on the back of the router.


3. Hold for about 30 seconds.

4. Release the button and all the lights will turn off, then on again. Now, the router is back to factory settings.

Secondary router configuration

To make the second router ready for use, follow these steps:

1. Turn off the main router or disconnect the PC from the network.

2. Connect the router to a computer that is not connected to the network.

3. Do the same with the old router until the configuration page is reached.

Copy settings from primary router

Now, the user needs to enter the information copied from the main router settings for the old router to use as a repeater.

1. Skip any setup wizard.

2. Go to the page Wi-Fi settings.

3. Activate wireless mode.

4. Change the network name like the primary router.

5. Select a channel that is away from the channel the main router is using.

6. Choose the same security type as the primary router.

7. Assign the same password as the primary router.

Assign the old router a fixed IP address

The router used as a repeater needs its own IP address.

1. Go to the LAN settings page and give the router an IP address within the range specified by the primary router, except those automatically assigned from DHCP (Dynamic Host Communications Protocol).

Assign an IP address

2. Disable DHCP by unchecking it on the configuration page.

3. Give it a new address, an address outside of the address specified by the router. For example, if the router provides word addresses come, Please provide a new address

4. Save the settings.

5. Wait for it to restart.

Putting all the elements together

The best way to connect routers is through a long network cable, but this may not always be possible. Instead, go for a cheap powerline adapter. It will use the electrical system as a signaling mechanism. Just make sure you are using a single electrical system connected to a fuse box.

Test everything

Now is the time to test the connections.

1. Choose a location between the WiFi dead point and the primary router.

2. Plug in the powerline adapter.

3. Attach the router to the adapter using the ethernet cable.

4. Turn on the router and try to connect.

5. Use a web page to test the connection speed near the primary router (eg

Checking connection

6. Check the speed of the secondary router and compare it with the previous results.

7. Move the secondary router to other locations to see if the connection is faster.

If you want stronger WiFi signal throughout the house, don’t be in a hurry to spend too much money on this, try the suggestions above first to see if it works for you!

Hope you are succesful.
