When the modem shows white or green light, it means the internet is on. On the other  hand, when the modem shows red light or no light, it indicates the problem with your modem and shows that your modem is not connected to the internet successfully. 

  • Check The WiFi Light

If you have a modem/ router combo unit, the WiFi light is situated below the internet connection light. There are multiple labels for WiFi lights, such as 2.4G, 5G, WLAN or Wireless, etc.

If these lights are blinking then it indicates the WiFi is working. And if the WiFi light is not blinking or showing red light then it indicates the router is not transmitting signals. 

2. Try Using an Ethernet Cable to Test your Connection

Try to plug your computer directly into your router with an Ethernet cable. If you can access the internet service, then it means the issue is with your WiFi service not the internet itself. Here are the steps to do so:

Basic WiFi Troubleshooting Steps

Let’s start with how to fix internet connection on PC. PCs tend to run into issues with WiFi. 

1. Restart Your Router 

If you are facing any problem with your WiFi then you restart your WiFi router or gateway. You must turn off your WiFi gateway or router for 60 seconds. After turning it on it might work.

2. Switch WiFi Bands(2.4 GHz and 5 GHz)

Maybe your router transmits WiFi over two frequency bands:

  • 2.4 GHz 
  • 5 GHz

Every frequency band has its strengths and weaknesses. The 5GHz is much faster than 2.4GHz and the 2.4GHz travels more than 5 GHz. 

If you are working far from the router try the 2.4 GHz and if you are working near your router then try the 5 GHz.

3. Test Your WiFi On Different Devices

You must try different devices to check whether your internet is working or not. For it, try to connect your laptop, mobile, or tablet to check if the internet is working. If other devices are working then it is the problem of a single device.

  1. Try a Different Ethernet Cable

You can try to swap your Ethernet cable with another one and plug it into your modem and router. Sometimes this formula works. 

  1. Change The Position of Your WiFi Router

You must select a place for your router, where it can send signals to all the devices equally. And you must avoid placing your router near any electronic devices or any disruptive surface.

You must place your router in a high place to increase its capabilities or provide better coverage of your home. The WiFi can pass easily through wood and drywall, but tile, metal, concrete, and water decrease WiFi coverage.
