Whether your ISP has sent you a new router or you just want to upgrade your current router, you will run into a problem.
What to do with the old router?
In the event of switching your ISP, you are often prompted to return your old device. But if you have a spare router running in that location, there are several ways to use it.
1. Build a wireless repeater
What to do if your Wi-Fi network does not cover the whole house? While you can opt for Powerline Ethernet adapters, adding a second router to your router is a good alternative.
This means connecting your old router to your new wireless network using a Wi-Fi signal. It can then share access to the Wi-Fi network, providing wider coverage. While there may be some latency issues, overall this is a quick and easy way to expand your wireless network.
It has a variety of uses, from providing better Wi-Fi access to a remote part of the house, to streaming video to your tablet when you’re out in the garden.
2. Guest WiFi connection
If you have people who regularly log in and use your wireless internet, why not give them their own network?
It’s similar to the wireless repeater project, but with a twist. The router connects to an existing password-protected network, but allows access to new devices without a password. This will use the guest network feature of your old router, which by default will prevent guests from accessing other devices on your network.
If this level of security is not enough, check the firewall settings on the main router for configuration.
3. Cheap Internet Radio Streamer
Want to enjoy your favorite radio stations online? Some routers can be configured to play internet radio if you are willing to install custom OpenWrt or DD-WRT router firmware.
Other software is also required, and you will need a USB sound card to output sound.
Even though it’s not a simple build and there are many other internet radio options available, it’s still a great project. This gives you an idea of the power of custom ROMs and also gives you an idea of how music is distributed over the internet.
4. Use your router as a cheap network switch
Most routers don’t have more than six Ethernet ports. With the rise of wireless technology in the home, this number may be even lower than four. But if you clearly need to connect devices via Ethernet, you may not have enough ports.
