Have you ever been lose internet during a meeting, show, or browse? You glance at your Huawei router and notice a red light on a wifi router blinking labeled LOS Light.
What does this mean, and how can you fix it? Don’t worry—we’ve got you covered!
In this blog post, we’ll explain what LOS means in the context of WIFI and share six effective ways to resolve the blinking red LOS light on your Huawei router. Let’s dive in and get your internet back up and running!
What Does LOS Mean in Wi-Fi?
LOS stands for “Loss of Signal.” When the LOS light on your Huawei router blinks red, it tells you that the router isn’t receiving a signal from your Internet Service Provider (ISP). Without this signal, your WiFi won’t work, leaving you disconnected.
This issue can stem from a variety of causes, from simple fixes like loose cables to more complex problems like ISP outages. Understanding the root cause is the first step to solving the problem.
Common Causes of the LOS Light Blinking Red
Before we jump into the fixes, let’s explore why the LOS light might blink red on your Huawei router. Here are the most common reasons:
- Disrupted or Poorly Connected Cables/Connectors: Loose or improperly plugged-in cables can interrupt the signal between your router and the ISP.
- Physical Damage to Cables: Cuts, fraying, or breaks in the cables can stop the signal from reaching your router.
- Damaged Pins or Optic Fibers: Faulty pins or broken optic fibers in the router or cables can block signal transmission.
- Unpaid Bills: If you’ve missed a payment, your ISP might suspend your service, triggering the LOS light.
- Scheduled Maintenance or ISP Issues: Maintenance or technical problems on your ISP’s end can temporarily disrupt your signal.
- Router Settings Problem: Incorrect or corrupted settings in your router might interfere with the signal.
Now that you know what might be causing the issue, let’s move on to the solutions!
6 Ways to Fix LOS Light Blinking Red on Huawei Router
You don’t need to be a tech expert to fix this Huawei router problem. Below are six practical steps you can take to stop the LOS light from blinking red and restore your internet connection.
1. Check and Secure Cable Connections
A loose cable is one of the simplest and most common culprits behind a blinking red LOS light. Here’s how to check your connections:
- Look at the cables connecting your Huawei router to the wall jack or ISP equipment.
- Make sure each cable is firmly plugged in at both ends.
- If you spot a loose or unplugged cable, pull it out and reinsert it securely.
- While you’re at it, check for visible damage like cuts or frayed spots. Damaged cables need replacing (see the next step).
You might be able to sort out your WiFi by tightening a loose connection!
2. Replace Damaged Cables
If you find a cable that’s cut, frayed, or otherwise damaged, it’s time to swap it out. A broken cable can’t carry the signal properly, leading to that pesky LOS light. Here’s what to do:
- Identify the damaged cable during your inspection.
- Get a replacement from your ISP or a local electronics store.
- Disconnect the old cable and plug in the new one, ensuring a snug fit.
You can use a fresh, undamaged cable can often solve signal loss issues instantly.
3. Reboot the Router
Sometimes, your router just needs a quick refresh to sort itself out. Rebooting can clear temporary glitches and restore the signal. Follow these steps:
- Find the power button on your Huawei router.
- Press and hold it for about 20 seconds until all the lights turn off.
- Wait 30 seconds to let the router rest.
- Press the power button again to turn it back on.
- Give it a minute to restart fully, then check if the LOS light stops blinking red.
This simple trick works more often than you’d think!
4. Check for Unpaid Bills
Believe it or not, an unpaid internet bill could be the reason behind your LOS issue. If your ISP hasn’t received payment, they might cut off your service. Here’s how to handle it:
- Log in to your ISP’s online portal or app to review your billing status.
- Look for any overdue payments or warnings.
- If you owe money, pay the bill right away to reactivate your service.
- Can’t access the portal? Call your ISP’s customer service to confirm.
Once you settle the bill, your internet should come back, and the LOS light should stabilize.
5. Contact the ISP for Maintenance or Site Issues
If your cables are fine and your bills are paid, the problem might lie with your ISP. Scheduled maintenance or technical difficulties on their end can disrupt your signal. Here’s what to do:
- Call your ISP’s customer support line or check their website for outage alerts.
- Ask if they’re performing maintenance or dealing with issues in your area.
- If so, get an estimated time for when service will return.
- If not, request further assistance or a technician visit.
Your ISP can pinpoint and fix problems beyond your control.
6. Reset the Router to Factory Settings
If nothing else works, resetting your router to its default settings might do the trick. Note that this wipes out all custom settings—like your WiFi name and password—so you’ll need to set them up again. Here’s how:
- Locate the reset button (often a small hole) on the back or side of your Huawei router.
- Grab a paperclip or pin and press the reset button for about 5 seconds, until the lights go off.
- Wait for the lights to come back on as the router restarts.
- Check if the LOS light stops blinking red.
- Log in to the router’s admin dashboard (check your manual for the default login) to reconfigure your WiFi settings.
For PLDT users, your ISP might provide a list of default admin usernames and passwords to use after the reset.
When to Call Your ISP for Help?
Tried all six steps and still see that blinking red LOS light? It’s time to bring in the pros. Contact your ISP for advanced troubleshooting.
They can check for network outages, test your line remotely, or send a technician to your home if needed. Don’t hesitate—sometimes the issue is out of your hands!
Tips to Prevent Future LOS Problems
Want to avoid dealing with the LOS light again? Here are some proactive tips:
- Inspect Regularly: Check your cables and connectors every few months for wear or damage.
- Ventilate Your Router: Place it in an open, airy spot to prevent overheating.
- Update Firmware: Log in to your router’s admin dashboard occasionally to install firmware updates.
- Pay on Time: Set reminders to keep your internet bills current.
- Use a UPS: In areas with frequent power cuts, a UPS (Uninterruptible Power Supply) can keep your router stable.
A little maintenance goes a long way toward uninterrupted WiFi!
