About the Optus Ultra WiFi Booster

The Optus Ultra WiFi Booster is a device that connects to your Home Internet modem to your WiFi coverage throughout areas of your home that may otherwise be out of range.

Below is compatibility information & how many Boosters you might need. If you've just received a new Booster, see our setup article.

There are two Optus Ultra WiFi Boosters available: Gen 1 and Gen 2.


The Optus Gen 2 modem and Booster will only be compatible with other Optus Gen 2 modems and Boosters.


If you have a Gen 1 modem (i.e. Sagemcom 5366TN or Optus Ultra WiFi (Gen 1) 5366 LTE) and want to add a Booster, you'll be provided with a Gen 1 Booster.

One Optus Ultra WiFi Booster (Gen 2) is usually enough to cover a home, but it will depend on factors such as Booster placement, wall materials and home configuration.
