Telstra Smart Wi-Fi Booster

Because every home is different. Some are not a standard shape, some have thick walls or multiple storeys and many have lots of devices all running at once.

Smart Modems create your home’s Wi-Fi network and are great at reaching most spaces, but if you do have a low coverage area, Wi-Fi Boosters are designed to help fill the gaps and enhance Wi-Fi coverage across your house. 

Yes, Telstra Smart Wi-Fi Boosters and Telstra Smart Modems are designed to work together. Here's the list of compatible modems: 

• Telstra Smart Modem 1.1 (DJA2030) 
• Telstra Smart Modem Gen 2 (LH1000, DJA2031) 
• Telstra Smart Modem Gen 3 (Cobra XH) 
• Telstra Smart Wi-Fi Booster Gen 3 is also compatible with Telstra Smart Wi-Fi Booster Gen 2 
• Telstra 5G Gen 2 Modem (Meteor2) 
• Telstra Smart Modem Gen 3 (CobraXH) 
• Telstra Smart Modem Gen 4 (NBN/Opticomm/Satelite) variant: Mongoose 
• Telstra Smart Modem Gen 4 (5G): Mongoose-5GFW.

If you don't have a compatible modem and you're on an eligible Telstra plan, you can upgrade to the Telstra Smart Modem 4 for $10 extra per month over 24 months (min cost $240 plus your chosen plan over 24 months) Prices may change.

Wi-Fi 6 mesh combines your modem and booster signals into one network, delivering fast, seamless connection throughout your home with no manual switching between devices.

Wi-Fi 6 mesh networks are ideal for large or multi-storey homes - letting you stream shows in the living room while your kids game upstairs and someone takes a video call in the backyard.

A Wi-Fi booster, sometimes called a Wi-Fi extender, amplifies and extends the coverage of an existing Wi-Fi network. It receives the Wi-Fi signal from your modem and rebroadcasts it to low Wi-Fi areas, helping to eliminate dead zones and improve connectivity in your home or office.

The main difference between a Wi-Fi booster and a Wi-Fi extender is how they interact with your existing network and broadcast the signal:

Wi-Fi extender:

• Rebroadcasts the existing Wi-Fi signal from your router.
• Typically creates a new network name (SSID), requiring manual switching between networks as you move.
• Setup can be less seamless, needing manual management of connections.

Wi-Fi booster:

• Meshes or pairs with your existing modem/router.
• Creates a single, unified Wi-Fi network name (SSID), allowing smooth device connection.
• Offers automatic connection to the strongest signal, often with advanced optimization features.

In summary, Wi-Fi boosters provide a more unified and smooth Wi-Fi experience compared to traditional Wi-Fi extenders.

Place it halfway between your modem and the dead zone, ideally in a central, open area away from thick walls, metal objects, and electronics like microwaves or TVs as they can interfere with your Wi-Fi.
