Turn Your Old Router into a Basic NAS Backup Box
To repurpose an old router as NAS, you turn a retired Wi‑Fi router with a USB port into a simple shared storage device that centralizes files and backups over your home network without buying a dedicated NAS enclosure. First, confirm your router has a USB port and supports SMB or similar file sharing in its firmware. Plug in a USB drive, then log into the router’s admin page and enable file sharing for that port. Create a user account or shared folder if the menu offers it. Next, connect your computers and phones to that router’s Wi‑Fi or Ethernet and map the shared drive from your operating system’s network file options. As How‑To Geek notes, this “budget NAS” will not be fast, but for light backups and a central media folder, it is far better than letting the hardware sit unused.
Set Up a Dedicated Print Server for the Whole Home
You can repurpose an old router as a dedicated print server to keep printers reachable from every room. If the router has a USB port that supports printers, connect your USB printer and enable printer or USB sharing in the router interface. If it lacks USB, connect a network‑capable printer to one of the router’s Ethernet ports instead. Disable its DHCP server so it does not hand out conflicting addresses, then connect the old router to your main network via Ethernet or keep it as an isolated local network if you want the printer offline. On each computer, add a new network printer, selecting the router’s IP address. This setup keeps printing reliable, avoids long USB cables, and lets phones, laptops, and desktops share the same device without moving cables around.
Create an Isolated Gaming Hub to Reduce Congestion
A spare router can become a gaming hub that keeps consoles and gaming PCs on their own segment, away from streaming boxes and smart TVs. Connect the old router to your main one with Ethernet, then disable its DHCP server and assign it a fixed IP within your primary network’s range. Plug consoles and gaming PCs into its LAN ports or connect them to its Wi‑Fi. Now you can enable QoS or traffic‑priority features on the old router, giving gaming devices preference over other traffic passing through that hub. Even without advanced features, separating gaming devices from the busiest part of your network reduces contention and keeps local traffic between those devices fast. For offline multiplayer, you can even disconnect the gaming router from the internet and still enjoy low‑latency local sessions.
Build a Smart Home Network Hub for Safer IoT Devices
To build a smart home network hub, you repurpose an old router into a separate network segment that isolates smart plugs, bulbs, cameras, and other IoT devices from your main computers and phones. Place the router near where most smart home gear lives, then connect it to your primary router with Ethernet. Disable its DHCP only if you want everything on a single IP range; otherwise, leave routing on and create a separate Wi‑Fi name dedicated to smart devices. Connect all IoT gadgets to that network instead of your main one. As How‑To Geek points out, routers do not need internet access to be useful, so you can even keep this smart home network local‑only for devices that work without cloud services. This extra layer of separation reduces risk if a cheaper smart device is compromised.
Use It as a Wireless Access Point for Dead Zones
One of the most practical ways to repurpose an old router is to turn it into a wireless access point for hard‑to‑reach areas without buying a mesh system. Many routers offer an AP mode in their settings; enable it and the device will stop routing and simply bridge wired and wireless traffic. According to How‑To Geek, you then connect the old router to your main router with an Ethernet cable so nearby devices get a strong signal and full speed. If there is no AP toggle, disable DHCP, give it a unique IP in your main network’s range, and use the same SSID and password (or different ones, if you prefer). Place the old router where signal from the main unit is still solid, and you will expand coverage to rooms that used to be dead zones.
