Re-registering your device

If you don't connect to the Trinity network for 75 days, then you will need to re-register your device.

Connecting at home

Keeping connected at home will require you to have an internet connection. The two most common options would be to use your home broadband or your smartphone as a Wi-Fi hotspot.

Having trouble connecting to your home broadband?

If you are having trouble connecting to your broadband, try these simple fixes first:

  • Check that any cables or wires are not disconnected from the broadband box
  • Reset your connection by 'turning the broadband box off and on again' – be sure to unplug the electrical plug, wait for a minute, and then plug it back in again
  • Check your service providers status pages to see if there are any reported outages. If so, your connection should come back on it's own once they resolve any issues they are having

Using your smartphone as a Wi-Fi hotspot

If you don't have access to a broadband connection, you could also use your smartphone as a Wi-Fi hotspot. It's useful to keep the following in mind when considering this option:

  • Wi-Fi hotspots use the data bundle of your mobile phone plan - so if you don't have an unlimited data plan it could use up all your credit
  • Protect your hotspot with a password so that others cannot use your data
  • Wi-Fi hotspots use a lot of power so your phone’s battery can run down quickly; keep your phone plugged in while using it as a hotspot
  • You may be able to have multiple devices connected to your hotspot, but remember the more devices that are connected to your hotspot, the faster your data allowance will go and the slower your connection may become
