Connecting to Fibre Broadband - TG587n V3

To receive a fibre broadband service, your home must have a fibre cable connection.

To set up your fibre broadband connection you must use a Windows or Mac computer with an ethernet port and a web browser. Due to the length of the cables supplied, you must set up close to the fibre termination port. Once your fibre broadband is working, you can unplug the ethernet cable and use the modem's wireless (WiFi) network.

  1. Connect Modem to ONT

  2. Connect Modem to Phone Socket (Optional) 
    If you want to use your Fibre modem to connect to an ADSL instead of Fibre, follow the steps below:
    • Connect the ADSL filter to the phone socket - do not use extension cords as they harm broadband stability and speed
    • If you use a telephone, fax machine, etc at the same phone socket, connect the device to the Phone socket in the filter
    • Connect the ADSL cable into the ADSL socket in the filter
    • Connect the other end of the ADSL cable into the grey coloured modem power marked DSL
