Frequently Asked Questions
What is the difference between Wi-Fi 6 and Wi-Fi 5?
Wi-Fi 6 (802.11ax) introduces OFDMA and MU-MIMO improvements that allow more devices to communicate simultaneously without congestion. It also delivers higher speeds, lower latency, and better performance in dense environments compared to Wi-Fi 5 (802.11ac). Wi-Fi 6 devices benefit most, but older Wi-Fi 5 and Wi-Fi 4 devices remain fully compatible.
How many Deco X20 units do I need?
The 2-pack covers up to 370 m², which suits most Australian homes. For larger properties or homes with challenging layouts, simply add a 1-pack or additional 2-pack to extend coverage — all units join the same mesh network automatically.
Does the Deco X20 work with my Australian ISP?
Yes. The Deco X20 is compatible with major Australian ISPs including Telstra, Optus, TPG, Aussie Broadband, and iiNet, and supports NBN FTTP, FTTN, FTTB, HFC, and fixed wireless connections.
What is Ethernet backhaul and should I use it?
Ethernet backhaul connects Deco units via a wired Ethernet cable instead of wirelessly. This dedicates the full wireless bandwidth to your devices rather than sharing it with the inter-unit connection, resulting in better performance — especially in larger homes. It’s optional but recommended where cabling is practical.
What is TP-Link HomeCare?
HomeCare is TP-Link’s built-in security and management suite that includes parental controls (per-device content filtering and time limits), antivirus protection powered by Trend Micro, and QoS for prioritising specific devices or applications. Basic features are included free with the Deco X20.
Can I manage the Deco X20 remotely?
Yes. The Deco app allows you to monitor connected devices, run speed tests, adjust parental controls, and manage your network from anywhere via your smartphone.
