We've identified nine ways you can reuse an old Wi-Fi router:
- Guest Wi-Fi connection
- Wireless repeater
- Cheap internet radio
- Use the old router as a network switch
- Adapt it as a wireless bridge
Build a Wireless Repeater
What if your Wi-Fi network doesn't extend across the full range of your home? Although you might opt for powerline Ethernet adapters, adding a second router into the mix is a good alternative.
This means connecting the old router to your new wireless network, using the Wi-Fi signal. It can then share access to the Wi-Fi network, giving greater coverage. Although there may be some latency issues, overall this is a quick and easy way to extend your wireless network.
Guest Wi-Fi Connection
If you have people regularly dropping in and using your wireless internet, why not give them their own network?
This is like the wireless repeater project, but with a twist. The router connects to your existing, password-protected network, but gives password-free access to new devices. This will use the guest network feature of your old router. By default, this prevents guests accessing other devices on your network.
Cheap Internet Radio Streamer
Want to enjoy your favorite radio stations on the internet? Some routers can be configured to play internet radio, if you're prepared to install OpenWrt or DD-WRT custom router firmware.
4. Use the Router as a Cheap Network Switch
Most routers don't have more than six Ethernet ports. With the increase in wireless technology around the home, this figure might even be as low as four. But with a clear need for devices to be connected over Ethernet, you might run out of ports.
5. Turn Your Old Router Into a Wireless Bridge
What if your new router is wireless only? Perhaps the ISP doesn't offer a router with Ethernet ports, or maybe you use a 4G internet provider. Either way, if you need to connect Ethernet devices to your home network, a wireless bridge is the answer.
