What do you do with old routers? Instead of tossing them in the trash, you can repurpose them to extend your Wi-Fi coverage, add wired ports, or create a separate guest network, but only after you perform a factory reset to wipe your personal data. This guide walks you through the practical, step-by-step ways to give your old router a second life, from turning it into an access point to recycling it responsibly if it's beyond saving.
What do you do with old routers instead of throwing them away?
Old routers are often discarded without a second thought, yet they contain hazardous materials like lead and mercury that can leach into the soil and water if they end up in landfills. Beyond the environmental risks, they also hold sensitive data, stored Wi-Fi passwords, login credentials, and network settings, that can be recovered by tech-savvy strangers if not properly erased. Instead of contributing to e-waste or exposing your privacy, you can repurpose the device to save money and improve your home network. The options include converting it into a wireless access point, a Wi-Fi extender, a network switch, a guest network, or even a home automation hub, all of which are detailed below. Before any repurposing, however, the critical first step is performing a factory reset to clear all personal information and settings, ensuring your data is safe and the router starts fresh for its new role.
How to perform a factory reset on your old router
The universal first step before any repurposing is a factory reset, which wipes all stored Wi-Fi data, credentials, and configurations from the device. Locate the small, recessed reset button on the back or bottom of the router, usually labeled "Reset" or marked with a tiny hole. Use a paperclip or a pen tip to press and hold the button for about 10 seconds while the router is powered on, then release it. The router will reboot, and all settings will return to their out-of-the-box state. This process is essential not only for privacy but also to eliminate any IP conflicts or custom configurations that could interfere with your new setup.
Use your old router as a wireless access point
If you have dead zones in your home where the Wi-Fi signal is weak, repurposing your old router as a wireless access point (WAP) is a smart solution. This setup extends your existing network's coverage without requiring expensive new hardware. To do this, first reset the old router to factory settings, then connect it to your main router using an Ethernet cable, plug one end into a LAN port on the primary router and the other end into a LAN port on the old router (not the WAN/Internet port). Next, log into the old router's admin interface and disable its DHCP server, since your main router will handle IP address assignment. Finally, configure the wireless settings to match your main router's SSID and password, so your devices automatically switch between the two access points seamlessly. Place the old router strategically in the area with weak coverage, and you'll enjoy consistent Wi-Fi throughout your space.
Convert your old router into a Wi-Fi extender
Another effective way to eliminate dead zones is to convert your old router into a Wi-Fi extender. This method works best when the old router is placed within the range of your main router's signal but close to the areas that need better coverage. Start by resetting the old router, then connect it to your main router via an Ethernet cable, using a LAN port on both devices. Access the old router's settings and disable DHCP to prevent IP conflicts, then configure its wireless network to use the same SSID and password as your main router. The old router will rebroadcast the signal, amplifying it to reach previously weak areas. Test the connection by walking around your home with a smartphone; you should see a stronger signal in the spots that were once problematic. This approach is ideal for large homes or multi-story buildings where a single router can't cover everything.
Transform your old router into a network switch
If you're running out of Ethernet ports on your main router, you can transform your old router into a network switch to add more wired connections. This is particularly useful for devices like desktop computers, gaming consoles, or smart TVs that benefit from a stable wired connection. Begin by resetting the old router, then connect one of its LAN ports to a LAN port on your main router using an Ethernet cable. Log into the old router's admin interface and disable the DHCP server and firewall to avoid conflicts with your main network. Now, you can plug additional devices into the remaining LAN ports on the old router, and they will receive IP addresses from your main router. Note that the speed of this switch is limited by the old router's hardware, if it only supports Fast Ethernet (100 Mbps), your wired connections will cap at that speed, but for most everyday tasks, this is perfectly adequate.
Create a guest network with your old router
Hosting guests often means sharing your Wi-Fi password, which can compromise your main network's security. Instead, create a guest network with your old router to provide visitors with internet access while keeping your personal devices isolated. Start by resetting the old router, then connect it to your main router via an Ethernet cable, LAN port to LAN port. Disable DHCP on the old router so your main router assigns IP addresses. Next, configure the wireless settings on the old router to create a new SSID with a unique password, this will be your guest network. You can even enable features like a guest portal or set time limits for access if your router supports them. Place the old router in a central location to ensure good coverage for your guests. This setup protects your main network from unauthorized access while still offering reliable internet to visitors.
Recycle your old router responsibly
If your old router is no longer functional or too outdated to repurpose, recycling it responsibly is the environmentally safe choice. E-waste contains hazardous materials that can harm the planet if dumped in landfills, so never toss it in the regular trash. Start by researching local recycling options, check for e-waste centers, electronics recycling events, or municipal collection programs in your area. Many manufacturers also offer take-back programs where you can mail in your old device for proper disposal. Before recycling, perform a factory reset to remove all personal data, and remove any batteries if applicable. Then, drop off the router at the designated facility or participate in a collection event. By recycling, you're preventing toxic chemicals from polluting the environment and contributing to a circular economy that recovers valuable materials like copper and gold for reuse.
