No Internet Access - Flashing Light On DSL Router

The ADSL light on the router is off or flashing and I have no internet access.

  • Check that the telephone cable provided with your router is plugged securely into your Telkom jack and at the back of the router.
  • Check that the telephone cable (RJ11) is directly into the Telkom wall jack from your ADSL router.
  • Check if you can connect the DSL line directly onto your Telkom jack, bypassing all POTS filters and lighting protection units.
  • If you notice any devices that may cause interference (line dropping) on the line, such as a home alarm, and electrical fencing, move the router away from it.


If all the above has been checked and you still experience a flashing/dead ADSL light on your router, please do the following steps below:

  • Contact our support desk on 0861003278 and advise the agent of the issue on the line.
  • If your DSL line is not managed by Cybersmart, you will need to contact Telkom on 10210 or the ISP that is hosting your line and report the fault.
