That old router in your drawer can still fix your worst Wi-Fi problems

Old routers collecting dust can be repurposed in several practical ways instead of being discarded. Three main use cases are covered: converting the router into a wireless access point or extender to eliminate Wi-Fi dead zones (with a tip to disable DHCP to avoid IP conflicts), setting it up as a dedicated VPN router so all connected devices automatically route through encrypted traffic using OpenVPN or WireGuard, and using it as a simple wired Ethernet switch by disabling DHCP and connecting it via a LAN port. Networking hardware ages slowly, making even six- or seven-year-old routers genuinely useful for solving common home network problems.
