If you are using a Linksys router with your Windows 11 PC and notice the router lights are flashing unusually, it can be confusing and concerning. These flashing lights often indicate network issues or errors that need attention.

This guide will help you understand what those flashing lights mean and walk you through simple, step-by-step solutions to fix the problem. No technical experience is required, and each step is explained clearly.

By following this guide, you can get your Linksys router back to normal functioning quickly and enjoy a stable internet connection again.

Let’s dive into the troubleshooting process to resolve your Linksys router light flashing error on Windows 11.

Quick Note: What to Check Before You Begin

Make sure your Linksys router is properly plugged into power and turned on.
Verify that all cables (power, Ethernet) are securely connected.
Check if other devices on the same network are experiencing connectivity issues.
Restarting your Windows 11 PC can sometimes resolve minor glitches.

Step 1: Power Cycle Your Linksys Router

Power cycling is the simplest and most effective first step. It helps clear temporary glitches in the router’s system.

Locate the power button on your Linksys router and turn it off.
Unplug the power cable from the router and wait for at least 30 seconds. This allows the internal memory to clear.
Plug the power cable back into the router and turn it on.
Wait for all lights to stabilize — this can take a couple of minutes.

If the lights are still flashing abnormally, move on to the next step.

Step 2: Check Your Internet Connection

The flashing lights may indicate an issue with your internet service rather than your router itself.

Make sure the Ethernet cable connecting your modem to the Linksys router is firmly plugged in.
Restart your modem by unplugging its power cable, waiting 30 seconds, and plugging it back in.
Once your modem is back online, check if the router lights stabilize.

This step ensures your internet source is active and working correctly.

Step 3: Update Router Firmware via Linksys Web Interface

Outdated firmware can cause connectivity and performance issues, including flashing lights.

Open your web browser on your Windows 11 PC and type 192.168.1.1 in the address bar, then press Enter.
Log in using your router’s username and password. The default credentials are often admin for both fields.
Navigate to the Firmware Upgrade or Administration section.
Check if a firmware update is available. If yes, download and install it following the on-screen instructions.
Do not turn off the router during the update as it can cause permanent damage.

Firmware updates fix bugs and improve router stability, which may resolve the flashing lights error.

Step 4: Reset the Router to Factory Settings

If other steps don’t work, resetting your router can fix configuration errors causing the problem.

Find the small reset button on the back of your Linksys router. It is usually recessed and requires a paperclip to press.
Press and hold the reset button for about 10 seconds until the lights blink rapidly.
Release the button and wait for the router to reboot. It will return to factory default settings.
After resetting, you will need to reconfigure your network settings through the router’s web interface.

Note: Resetting erases all personalized settings, so only do this if you have your network information or are comfortable setting it up again.

Alternative Method: Use the Linksys App for Troubleshooting

Linksys offers a mobile app that can help diagnose and fix common router issues.

Download the Linksys App from the Microsoft Store or your phone’s app store.
Open the app and connect it to your router following the prompts.
Use the app’s troubleshooting tools to identify problems and apply fixes automatically.

This method is user-friendly and recommended for less technical users.
