    Setup Wizard Step 1 If you have a Pentanet Fixed Wireless, NBN HFC or NBN FTTP service (ethernet connection type), please select “ethernet WAN” in the “WAN Interfaces” dropdown. For NBN FTTN or FTTB services (RJ11 phone socket connection type), please select ‘VDSL’. Image

    Setup Wizard Step 2 Select 'I don’t have VOIP’ If you have a VoIP phone from a third party provider, we still recommend selecting ‘I don’t have VoIP”, and setting this up in the Telephony Section later, after the service is connected.

    Setup Wizard Step 7 - Security In this step, you can change the administrator login for your device (the credentials you used in #2). If you change this, please write it down safely. If you misplace this password, you will need to factory reset the device and follow this process again.

    Setup Wizard Step 8 - Summary Check through all the settings and click Finish when completed. Give the router a around 15 minutes to stabilise and connect.

And that’s it!

Note: The Technicolor TG789 has two Wi-Fi networks which broadcast on different frequencies - 2.4GHz and 5GHz. 5GHz can reach faster speeds, but doesn’t penetrate walls well. 2.4GHz travels farther, but often won’t be as fast. We recommend using the 5GHz network when you’re nearby the unit, or the 2.4GHz if you’re in a different room or further away.
