Why Is My PLDT Router LOS Blinking Red Light?

An issue with the internet connection is typically indicated by a blinking red LOS light on a PLDT router.

A number of factors can contribute to the loss of signal on your PLDT modem. The blinking or steady red light indicates a loss of signal.

As a result, your modem may be able to establish a local network connection for your personal devices, but cannot communicate with your ISP due to signal loss. # PLDT Router LOS Blinking Red

Here are some possible causes:

  1. Damaged or loose patch cord.
  2. An extreme bend in a fiber cable.
  3. The fiber cable connected to your modem from your pole / NAP box is damaged.
  4. Your ISP is performing scheduled maintenance or upgrading equipment in your area, resulting in an outage.

Here are a few solutions you may try to fix the LOS red light on your modem:

  1. Power Cycle your Modem/Router: Switch off your modem for five minutes and then turn it back on to refresh your connection. Wait for the modem to sync within 3 minutes. Check the LOS light indicator.
  2. Check for loose cables: The connections between your modem and fiber optic terminal box or indoor optical outlet (the small white box attached to your wall) probably became loose over time. Make sure all cables are properly attached.

It may be necessary to send a technician to your Internet Service Provider if the problem persists. The blinking LOS light indicates there is no Sync from the modem to the ISP server. # PLDT Router LOS Blinking Red # Why Is My PLDT Router LOS Blinking Red Light

How To Fix PLDT Router LOS Blinking Red?

If the LOS light blinks red on your PLDT router, it may be an indication of a variety of issues that disrupt your internet connection.

Here’s a guide on how to troubleshoot and possibly resolve this issue:

Check Physical Connections:

The PLDT router cable should be securely plugged into the router. The DSL cable (phone line) should be properly inserted into the router’s DSL port and the wall jack.

Checking the following would be the first step in this case:

  • Make sure the fiber optic cable is connected properly to the modem.
  • The condition of the object, including any damage or abnormal bends.
  • Check for loose or damaged connectors.

Make sure that every end of the fiber optic cable is checked and that a new one is purchased if necessary.

This next solution should be tried if the LOS light continues to blink red after this inspection and the eventual cable replacement or reconnection.

Power Cycle the Router:

This simple step can often resolve minor connectivity problems by turning on the router, waiting about 30 seconds, then turning it back on again.

Inspect for External Interference:

If there are any possible sources of interference near the router, such as electronic devices and wireless gadgets, keep the router away from such obstructions.

Test the DSL Line:

To determine if there are any issues with your DSL line, test it with another device (if possible) or contact your internet service provider (PLDT).

Reboot and Reset the Router to Factory Settings:

Many networking problems can be solved with this quick fix since it is highly effective and easy to implement. When experiencing some problems with your home network, don’t forget to try this quick fix.

Disconnect the router’s power cord from the electrical outlet and wait 5 minutes to reboot it. Once it has booted up completely, connect it back to the outlet and check for the red blinking light.

It is very likely that it is off now, but if it is still on, try the next solution.

Occasionally, a factory reset might be necessary. Press the reset button (usually on the back of the router) for around 10-15 seconds for the router to be reset to its default settings.

Update Firmware (if applicable):

The router’s administration panel can be accessed by logging in and checking for firmware updates. In some cases, outdated firmware will cause connectivity issues.

If available, update the router’s firmware as soon as possible.

Contact PLDT Support:

A persistent issue may require more than basic troubleshooting. Contact PLDT customer service for assistance. They might be able to run diagnostics for you or schedule a technician visit.

In case the problem persists after trying these steps, you may want to ask your internet provider for more specialized assistance. These steps are intended to address common issues that cause the LOS red blinking on PLDT routers.

How to contact an Internet service provider?

The final resort when troubleshooting persistent LOS (Loss of Signal) issues is to seek assistance from your Internet Service Provider (ISP). A thorough investigation into the root cause of your LOS issue can be conducted by contacting your ISP’s customer support.

In addition to providing expert guidance, this step facilitates a thorough investigation into the root cause.

The Customer Service Representative (CSR) for your ISP will perform a line test to diagnose and pinpoint the exact cause of the LOS indicator on your PLDT router when you contact them. # contact an Internet service provider

In order to determine the health of your network and determine what steps need to be taken to resolve it, this test is essential.

Following the assessment, the CSR will initiate the process of resolving the problem by issuing a repair, support, or service request.

Prepare yourself before contacting your ISP to ensure a swift resolution. In addition, some ISPs may request the modem serial number for effective troubleshooting.

Have the following information readily available: your landline number, your account name, your account number, your address, and a scanned valid ID. # contact an Internet service provider
