D-Link Router WiFi Light Not On? – Learn How to Fix

Wondering why the D-Link router WiFi light not ON even when connected?

There could be quite a few different reasons for the WiFi light.

If one thing is for sure is that without the WLAN light, you won’t be able to connect to the router’s internet.

Let’s learn more!

When the WiFi Light on a D-Link router is not ON, users should reconnect the internet cable from the yellow port on the back of the router and power cycle the device. When a modem is involved in the setup, users should reconnect the Coax connection as well.

What is the “WiFi Light” On a D-Link Router?

As the label of the lamp on your D-Link router suggests, this light indicates whether the WiFi is online or not.

If the lamp is in the solid green light, then the WiFi connection is reliable and you could connect with the network.

In contrast, the red, blinking yellow, or no light means that there is a WiFi issue with your D-Link router that needs checking.

Let’s learn more about why there is no green light!

Why is the D-Link Router Internet Light Not On?

There could be multiple reasons, causing the internet light to go off:

• No connection from the DNS Server (ISP outage)
• Power or functionality problem with your D-Link router
• Wiring/Cable or Interference Problem

It’s really important that your router is free of interference.

The lighter the WiFi signal your router transmits, the easier it could interfere with other over-the-air signals.

Let’s next proceed with solving any potential issues with the Internet supply on D-Link!

How to Fix When D-Link Router WiFi Light Not On?

The solution to the lack of internet income problem on the D-Link router involved following a chronological list of solutions to help us identify and solve the problem.

It’s important not to skip any of the solutions to be able to bring back the connectivity until the end of the guide.

Solution #1 Hard Reset the Router

Performing a Hard Reset, also known as a “Power Cycle” on your D-Link router will discharge the device and hopefully refresh the internet connection.

As we’ve already clarified, the WiFi lamp indicates whether the router is online or offline.

To easily solve this problem, you should hard reset the router!

Here’s how to perform a hard reset on your router in easy steps:

1. Turn off the D-Link router by pressing its Power Button.
2. Unplug the Power Adapter of the network device.
3. Standby for 5 Minutes while the router discharges.
4. Reconnect the power cable of the router.
5. Turn the device on and wait for it to start up completely.
6. Check if the WiFi lamp is still off.

It’s important to avoid plugging your network router device into a power strip and use a standalone wall outlet. This will prevent power fluctuations making your device restart.

Alert: At first the WiFi (WLAN) Light will be blinking as an indication of working!

Solution #2 Reconnect the Internet Cable

There could be an issue with your internet cable or rather, its connection.

Based on the type of your setup (a standalone router or a router-modem combo), you should reconnect the internet cable to resolve the problem.

The internet cable is connected to the blue Ethernet input port on your router/modem!

Here’s how to reconnect the internet cable with a stand-alone D-Link router:

When Using a Stand-Alone D-Link Router:

1. Turn off the Router.
2. Disconnect the internet cable from the router.
3. Wait for 5 Minutes.
4. Reconnect the Internet cable.

When Using a Router-Modem Combo:

1. Repeat the same steps as when using a standalone router.
2. Disconnect the Ethernet Cable from your modem.
3. Standby for 5 Minutes.
4. Set up all the cables securely.

Now when the cables are reconnected, restart your router and wait to find out whether the WLAN (WiFi) light will start blinking. In case it does, test connecting to the WiFi.

Note: Do not plug the Internet Cable into a yellow Ethernet port on the router/modem!

Solution #3 Refresh The Coax Modem Connection

Your modem could be having power issues, which could also result in an offline router and blank WiFi light on the device.

A great way to resolve problems with your modem, is to power refresh the device, using the coaxial cable and the power button on the device.

Here’s how to perform a power refresh on your modem (if you’re using one):

1. Press and hold the Power Button on the modem.
2. Hold the button down for 60 Seconds.
3. Let go of the button.
4. Disconnect the Coaxial Cable from the phone jack.
5. Wait for another 3 Minutes.
6. Reconnect the coaxial cable and turn on the modem.
7. Check if the WiFi light on your D-Link router is still blank.

With the Coaxial input refreshed, you should once again, restart your router/modem and check whether the WiFi light will turn on this time. In case it doesn’t proceed further!

Note: After the refresh, it might take up to 3-4 minutes until the WiFi lights turn on.

Solution #4 Replace the Network Cables

There could be a fault in the network cables in your setup.

Especially if you’re using a modem along with your D-Link router, there are overall 2 independent network connections that must be healthy for the router’s WiFi to work.

Let’s review the different network cable connections in both setups:

Network Connections in Router-Modem Setup:

Here are the network cable connections in your router-modem setup:

• Internet cable connecting the phone jack with the modem!
• Internet cable connecting the modem and the router

Network Connections In a Standalone Router Setup:

Those are the network cable connections in a standalone router setup:

• The coaxial cable connecting the router with the phone jack

Identify your setup and replace the appointed network connections. Only then, check if the WiFi light on your D-Link router is listed. Don’t forget to restart your devices after!

Note: Avoid using second-hand or old Ethernet cables to fulfill the network connections!

Solution #5 Reset the D-Link Router

You should perform a reset on your D-Link router if it is still giving you trouble with the WiFi light.

A reset will refresh the software of the router, clearing the cache and removing glitches that are causing the unit to go offline and the WiFi light to go off.

Here’s how to reset your D-Link router:

1. Make sure that the D-Link router is upand running.
2. Grab a thin object to use for the reset (paper clip, needle, toothpick).
3. Turn the router the other way so the ports are in front of you.
4. Locate the Reset Pinhole near the yellow Ethernet port.
5. Use the instrument you’ve acquired for the reset and insert it into the hole.
6. Keep holding the reset button for 10 Seconds.
7. The unit will reboot automatically.

Notice: Do not unplug, turn off or interact with the router before the reset is finished.

Solution #6 Replace Router Power Adapter

If the problem with the WiFi light persists even after the reset, then most certainly, your router isn’t receiving any proper charge.

That problem could be caused by an issue with the power supply of the device (the power adapter).

The easiest way to solve the issue is to replace the power equipment.

There are designated power adapters for D-Link routers at us.dlink.com for order.

The D-Link routers use a 12V 1AMP Power Adapter which you could acquire from Amazon at a very approachable price.

Get the replacement unit and remove the old power adapter in your D’Link router setup.

Now, install the new power adapter and check how your router works.

If everything with the router seems okay, but the WiFi light still doesn’t come on, perhaps it’s time to get in touch with your ISP for more assistance.

Check whether the problem is not on their side!

Quick Recap:

Thus, the D-Link router WiFi Light is off when the device is not receiving enough power to turn ON or when the cable connections are loose. We’ve learned that to solve the problem we need to inspect each aspect and act accordingly.
