Many households have old routers collecting dust, but these devices can still serve valuable purposes. One of the simplest uses is to convert an old router into a wireless extender or secondary access point, effectively eliminating Wi-Fi dead zones. This can be achieved by disabling DHCP and either connecting it via Ethernet to the primary router or using it in repeater mode. Additionally, old routers can be transformed into dedicated VPN routers, allowing all connected devices to benefit from encrypted internet traffic without needing individual VPN installations. This setup not only enhances privacy but also enables users to create separate networks for guests. Furthermore, if your workspace is near your primary router, you can use the old router as a wired switch, providing stable Ethernet connections for devices like laptops and PCs. Overall, repurposing old routers not only extends their life but also significantly improves home network performance, making them a valuable asset rather than e-waste.
