Frequently Asked Questions
Which Australian 5G networks does the Deco X50-5G support?
The Deco X50-5G supports Sub-6 GHz 5G NR bands used by Australian carriers including Telstra, Optus, and Vodafone/TPG. Check the TP-Link AU product page for the full band list and confirm compatibility with your preferred carrier and plan before purchasing.
Do I need an NBN or fixed-line connection?
No — the Deco X50-5G has a built-in 5G modem. Insert a nano SIM from a compatible Australian carrier and you have broadband immediately. It also supports a fixed-line Ethernet WAN connection if you want to use it alongside or instead of 5G.
Can it automatically switch between 5G and my fixed-line connection?
Yes. The Deco X50-5G supports dual WAN with automatic failover. Connect your fixed-line modem to the 2.5 Gbps Ethernet WAN port and insert a 5G SIM — if either connection drops, the unit switches automatically to keep you online.
Can I add more Deco units to extend coverage?
Yes. The Deco X50-5G is fully mesh-compatible. You can add additional Deco units to extend coverage throughout larger homes or properties. All units are managed through the single Deco app with one unified network name.
Does it support external 5G antennas?
Yes. Two TS-9 antenna ports are included for attaching optional external directional or high-gain 5G/4G antennas — particularly useful for rural properties or locations with weak mobile signal.
Is a SIM card included?
No — a SIM card is not included. You will need to purchase a 5G data SIM from your preferred Australian carrier (Telstra, Optus, Vodafone, or an MVNO) separately. Ensure your plan supports use in a router or home broadband device, as some mobile plans restrict hotspot or router use.
