I've lost my Internet connection, what do I do?

Written by KCOM Support on 23/03/2022. Posted in Broadband.

If you're having trouble getting onto the internet, there may be several possible reasons.

First, check our support page to see if we have any service issues. If there are no service issues currently, we have some steps below that may help to resolve the issue.

Step one: Checking the ONT (Lightstream customers)

The first thing to check would be the ONT box on your wall (this is the box that your router plugs into).

  • Power light should be solid green
  • Optical light should be solid green
  • LAN1 light should be green (flashing or solid)

If the power light or optical light on your ONT are off, flashing or red, this means the issue is our side. Please call us on 01482 606101 so we can look into this.

Step two: Checking the lights on the router

  • Broadband, WAN or DSL light is off

    This would indicate that your router has lost its connection to us and isn't picking up a fibre or DSL connection.

    Possible solutions:
     
    • For Lightstream, check that the Ethernet cable is plugged into the WAN port on your router. Check that the other end is plugged into the LAN1 port on your ONT.
       
    • For ADSL broadband, check that the DSL cable is plugged into a microfilter which in turn should be plugged into your main telephone socket
       
    • Are you a new customer? If so, your connection might not have been activated yet. You can check this by calling 01482 602555.
       
    • If none of the above work, please call us on 01482 606101 so we can troubleshoot your connection
       
  • Internet, World or Globe light is red

    This would normally indicate that there is an issue with your router settings or the username and password on your router is incorrect.

    Possible solutions:
     
    • Turn your router off by using the power button, wait 10 seconds and then turn it back on again to see if your Internet light goes green
       
    • Factory reset your router by pushing a pin into the reset hole on the back of your router for 10 seconds - your router should set itself up again automatically
       
    • Check your router settings by and make sure your KCOM username and password are correct
       
    • If none of the above work, please call us on 01482 606101 so we can troubleshoot your connection

     
  • All lights are green

    If all of your lights are on and green but you cannot get online, you've probably lost your wireless connection.

    Possible solutions:
     
    • Turn off the Wi-Fi on your device and then turn it back on - this refreshes your wireless connection and may help you get back online
       
    • If possible, plug your device into the router with an Ethernet cable and see if you can browse the Internet. If this didn't work, please call us on 01482 606101 so we can troubleshoot your connection
