How to Fix Router Not Working or Not Responding

✅ Quick Answer

If your router is not working or not responding, it usually happens because of outdated firmware, overloaded router memory, corrupted settings, or power issues. The most effective fixes are to restart the router, update firmware, reset configuration, and check power cables.

❓ Why Does Router Stop Responding?

Routers can stop responding due to software glitches, overheating, or hardware failure. Sometimes, a sudden power surge or a faulty cable causes the router to freeze and stop broadcasting Wi-Fi.

Another common reason is outdated firmware. Router firmware is the internal software that controls the router. If it becomes old or corrupted, the router may freeze, restart randomly, or stop working.

🔧 Fix 1: Restart Router & Modem

Restarting is the fastest fix and often resolves temporary bugs.

Turn off the router and modem.
Unplug power cables from both devices.
Wait 60 seconds.
Plug the modem back in first.
Wait 2 minutes, then plug the router back in.
Wait 2 minutes and check the Wi-Fi again.

🔧 Fix 2: Check Power Supply & Cable

A weak power supply or damaged cable can cause the router to freeze.

Use the original adapter (correct voltage).
Check for cable damage or bending.
Try a different power socket.
If possible, test with another compatible adapter.

🔧 Fix 3: Update Router Firmware

Firmware update fixes bugs and improves stability.

Open your browser and enter router IP (usually 192.168.1.1).
Login with admin credentials.
Go to System / Firmware Update.
Click Check for Updates and install.
Restart the router after update.

🔧 Fix 4: Reset Router Settings

Resetting restores default settings and removes corrupted configuration.

Find the Reset button on the router.
Press and hold for 10–15 seconds using a paperclip.
Router will restart automatically.
Reconfigure Wi-Fi name and password.

🔧 Fix 5: Check Overheating & Placement

Routers overheat when placed in closed spaces or under heavy load.

Place router in open area with airflow.
Avoid direct sunlight and tight cabinets.
Keep it away from microwave and other electronics.
Consider a cooling pad if it gets very hot.
