Need a broadband modem replacement?

Modem warranty replacements

The two types of cover available are:

  • Out Of Box Failure: This covers device failure within the first 28 days of you receiving the modem. It also includes if you have received hardware with missing components.
  • Warranty Repair: This covers your device for up to 24 months from the date of receiving the modem or original purchase.
    If you receive replacement hardware during the warranty period, the new hardware will continue to be covered under the remaining warranty of the original device. For exclusions, see damages not covered by warranty. 

We will replace a modem we supplied at no extra charge when:

  • The modem we supplied is diagnosed as faulty by our Service Representative and 
  • Less than 2 years old and
  • Is not damaged in a way not covered by warranty

We may ask you to perform troubleshooting steps to identify a fault before sending a replacement modem.
