This guide provides step-by-step instructions on repurposing an old router as a Wi-Fi extender, also known as a wireless internet repeater, to enhance network coverage in areas with weak signals at home or in the office.
For optimal performance, the spare router should support at least the 802.11n Wi-Fi standard. Older models may not deliver the required internet speeds when used as extenders.
How to Use a Second Router as an Extender?
The simplest method to use an extra router as an extender is by linking it to your primary router via an Ethernet cable. Although router settings and terminology can vary among models, the setup process generally follows these steps.
Specific instructions for your router's model should be available through the manufacturer or internet provider's website.
Update the firmware on your old router. If the router hasn’t been in use for a while, updating it can enhance internet connectivity and security.
Connect an Ethernet cable from an Ethernet port on your main router to the WAN port on the secondary router intended for use as a Wi-Fi repeater.
Access your secondary router’s admin settings by entering its IP address and login credentials.
This information is usually available on a sticker attached to the router or can be found in the router's manual or packaging. These are the same admin settings used for changing a modem or router’s password.
Once logged in, navigate to the router’s wireless settings and select AP Mode. This configuration transforms your router into an access point, extending the Wi-Fi beyond the primary router’s range.
You might need to click an option like Apply, Confirm, or Save to activate the changes.
How to Configure Your Router as a Repeater?
Another option besides AP Mode is to set up your additional router in Repeater mode. This method is suitable if you don’t have an Ethernet cable available. Here's how to proceed:
Ensure that your main router is powered on and broadcasting its Wi-Fi signal.
Update the firmware on your old router to access the latest security enhancements and features.
Access the admin settings of your old router through a web browser or its official app.
Check the router's bottom for login information.
Locate the old router’s wireless settings and select Repeating Mode.
The terminology and steps may differ depending on your router’s model. Repeating Mode might also be referred to as Wireless Bridge Mode, Extender Mode, Repeater Mode, or a similar term.
Choose the Wi-Fi network created by your primary router and connect to it using the password and, if required, username.
This step's procedure varies significantly based on the router you are using. You might need to input your main router’s IP address or MAC address, along with admin information, instead of or in addition to the Wi-Fi network login details.
Confirm the changes.
How to Use an Old Router as a Wi-Fi Extender Without Cables?
The simplest way to repurpose an old router as a Wi-Fi extender without an Ethernet cable is to set it up in Repeating Mode. In Repeating Mode, the router wirelessly connects to the Wi-Fi signal produced by the primary router and extends the wireless network coverage in its vicinity.
When utilizing an old router as a Wi-Fi repeater, keep in mind that it must establish a wireless connection with the primary router, and this connection may be disrupted or weakened by physical barriers like walls. Try positioning the router away from walls, furniture, and other obstacles.
Can I Use a Router as a Wi-Fi Extender?
Most modern routers and modem-router hybrids support Wi-Fi extension functionalities. Although many older routers can also serve this purpose, it's advisable that they support at least the 802.11n Wi-Fi standard. Routers with older Wi-Fi technology may function but might not deliver the desired speeds or stability.
Certain routers, such as the Asus AiMesh product line, offer additional support for Wi-Fi extension through their own mesh networking system. A wide range of Wi-Fi extenders is available from various manufacturers and retailers. These dedicated devices are often cost-effective and simpler to set up compared to other strategies for boosting or extending Wi-Fi coverage.
