How to fix router not working - complete troubleshooting guide

Understanding Router Lights

Before troubleshooting, check your router's indicator lights:

LightStatusMeaning
PowerSolid GreenRouter is powered on properly
PowerOffNo power — check cable/outlet
Internet/WANSolid GreenInternet connection is active
Internet/WANRed/OrangeNo internet from ISP
WiFiBlinkingWiFi is active and transmitting
WiFiOffWiFi is disabled

Fix 1: Power Cycle Your Router

A proper power cycle fixes most router problems:

  1. Unplug the router from the power outlet
  2. If you have a separate modem, unplug that too
  3. Wait 60 seconds (important — let capacitors discharge)
  4. Plug in the modem first, wait until all lights stabilize (2 minutes)
  5. Then plug in the router, wait for it to fully boot (2 minutes)
  6. Test your internet connection

Fix 2: Check All Cable Connections

Loose or damaged cables are a common cause of router problems:

  • Check the power cable — make sure it's firmly connected
  • Check the Ethernet cable from modem to router (WAN port — usually yellow or blue)
  • Try a different Ethernet cable
  • Make sure the cable is in the WAN/Internet port, not a LAN port
  • Check for bent or damaged cable ends

Fix 3: Check if ISP Has an Outage

Before troubleshooting your router extensively, confirm your ISP is working:

  • Check your ISP's website or app for outage reports (use mobile data)
  • Search "[Your ISP name] outage" on Twitter/X
  • Visit downdetector.com to check for reported outages
  • Call your ISP's customer support to ask about outages in your area

Fix 4: Factory Reset Your Router

If your router is unresponsive or misconfigured, a factory reset restores default settings:

  1. Find the small reset button on the back of your router (usually a pinhole)
  2. Use a paperclip or pin to press and hold the reset button
  3. Hold for 10-15 seconds until lights blink
  4. Release and wait for the router to restart (2-3 minutes)
  5. Connect to the default WiFi network (check the label on your router)
  6. Reconfigure your WiFi name, password, and other settings

Important: Factory reset erases all custom settings including WiFi name, password, port forwarding, and parental controls.

Fix 5: Update Router Firmware

  1. Log into your router's admin panel (192.168.0.1 or 192.168.1.1)
  2. Enter admin credentials (default is often admin/admin — check router label)
  3. Find System/Administration → Firmware Update
  4. Click Check for updates or download firmware from manufacturer's website
  5. Install the update and wait for router to restart

Fix 6: Change Router Channel and Band

WiFi interference can make your router appear to not work properly:

  1. Log into router settings
  2. Go to Wireless Settings
  3. Change channel to 1, 6, or 11 (for 2.4GHz)
  4. Enable both 2.4GHz and 5GHz bands
  5. Set the channel width to 20MHz for 2.4GHz (more stable)

Fix 7: Check for Overheating

Routers can overheat and malfunction, especially if placed in enclosed spaces:

  • Touch your router — if it's very hot, overheating may be the issue
  • Move it to a well-ventilated area
  • Don't stack other devices on top of the router
  • Keep it away from direct sunlight and heat sources
  • Let it cool down for 15-20 minutes before restarting

Fix 8: Try Connecting Directly to Modem

To confirm the problem is your router and not the internet service:

  1. Disconnect your router from the modem
  2. Connect your computer directly to the modem with an Ethernet cable
  3. Test internet — if it works, the router is the problem
  4. If internet doesn't work even connected to modem directly, call your ISP

Fix 9: Reduce Connected Devices

Too many devices can overwhelm your router:

  • Check how many devices are connected in your router's admin panel
  • Budget routers may struggle with more than 15-20 devices
  • Disconnect devices you're not using
  • Consider upgrading to a WiFi 6 router that handles more devices

When to Replace Your Router

Consider buying a new router if:

  • Your router is more than 5 years old
  • It doesn't support WiFi 5 (802.11ac) or WiFi 6 (802.11ax)
  • It frequently needs restarting
  • Your internet plan exceeds the router's maximum speed capability
  • You've tried all troubleshooting steps without success

FAQ

Why is my router's internet light red?

A red internet light means your router cannot connect to your ISP. This could be an ISP outage, a problem with your modem, or an issue with your internet account. Contact your ISP for assistance.

How often should I restart my router?

Restarting your router once a week is recommended for optimal performance. Some newer routers can run for months without needing a restart.

What is the difference between a router and a modem?

A modem connects your home to your ISP's internet service. A router creates a local network (WiFi) and shares that internet connection with all your devices. Many ISPs provide a combo modem-router device.

Conclusion

A router not working is usually fixable with a simple power cycle or cable check. Start with the basics — restart your router, check cables, and verify your ISP isn't having an outage. If problems persist, update the firmware or do a factory reset. Remember, routers don't last forever — if yours is over 5 years old, it might be time for an upgrade.
