To use your old router as a Wi-Fi extender, connect it to your primary router via Ethernet and set it to AP Mode.
To use an extra internet router as a wireless repeater without a cable, put it in repeating mode. Depending on the router manufacturer, certain models may have different names for settings and specific steps.
With OpenWrt firmware, you can easily convert your outdated router into a wireless bridge that connects networks wirelessly.
How to Turn an Old Router Into a Wireless Bridge
- Connect your old router to the main router.
- Plug your computer into the old router using a cable and turn off Wi-Fi.
- Download OpenWrt Firmware
- Go to openwrt.org and find your router model.
- Download the firmware files for your router.
- Install OpenWrt Firmware
- Follow the instructions given by OpenWrt’s website to install the firmware on your router.
To set up the Wireless Bridge
- Install a software called luci-proto-relay on your router.
- Set up the old router to have a fixed IP address and to stop sharing IP addresses.
- Link the old router to the Wi-Fi network of the main router.
- To build a bridge, link the wired and Wi-Fi connections to the old router.
For the Complete setup
- Check that the two connections are located in the same network area.
- Save your changes and apply them.
- Disconnect the cable between the old and main routers.
What is a Wireless Bridge?
A wireless bridge allows internet access by bridging a long distance between a fixed device and a router (or standard internet setup), is to say an association between two endpoints is called a wireless bridge.
These endpoints could be corporate WANs, buildings, telecom masts, and CCTV cameras.
The process of creating a WiFi connection between two devices is how a WiFi bridge operates.
Devices on one network can then communicate with devices on the other to exchange data, and vice versa. In particular, WiFi bridges use a point-to-point wireless bridge connection to link to routers.
