Fast, Reliable Wi-Fi 6 for Australian Homes with NBN Compatibility and OneMesh Support
The TP-Link Archer AX1800 brings Wi-Fi 6 (802.11ax) to Australian homes at an accessible price point. With combined speeds of up to 1.8Gbps across dual bands, OFDMA for handling more devices simultaneously, Beamforming for improved range, WPA3 security, and OneMesh compatibility for whole-home coverage, it's a meaningful upgrade over older Wi-Fi 5 routers. Compatible with all NBN connection types and all existing Wi-Fi devices, it sets up in minutes via the Tether app.
Key Features
AX1800 Wi-Fi 6 Speeds: Up to 1.8Gbps combined across 5GHz and 2.4GHz bands — faster and more efficient than Wi-Fi 5 for everyday streaming, browsing, and gaming.
OFDMA Technology: Communicates with multiple Wi-Fi 6 devices simultaneously rather than sequentially, reducing latency and improving performance in homes with many connected devices.
4× High-Performance External Antennas with Beamforming: Focuses Wi-Fi signal towards connected devices to extend range and improve reliability throughout the home.
WPA3 Security: The latest Wi-Fi security protocol provides stronger encryption and enhanced protection against brute-force attacks compared to WPA2.
TP-Link OneMesh Compatibility: Pairs with OneMesh-compatible TP-Link extenders to create a seamless whole-home mesh network with a single Wi-Fi name and automatic roaming.
Free Parental Controls: Block inappropriate content, set time limits, pause internet access, and manage profiles for individual devices — all free via the Tether app.
NBN & ISP Compatible: Works with all NBN connection types (FTTP, FTTC, FTTN, FTTB, HFC) and supports L2TP and PPTP authentication for a wide range of ISPs. IPTV support included.
New Device Notifications: Receive a push notification when a new device connects to your network — quickly identify and block suspicious connections from the Tether app.
OTA Firmware Updates: Automatic over-the-air firmware updates keep your router secure and up to date without manual intervention.
Backwards Compatible: Works with all existing Wi-Fi devices (802.11a/b/g/n/ac) — no need to replace any current devices.
Easy Setup via Tether App: Get connected in minutes using the free TP-Link Tether app on iOS or Android.

Frequently Asked Questions
Is the Archer AX1800 compatible with the NBN?
Yes. The Archer AX1800 is compatible with all NBN connection types including FTTP, FTTC, FTTN, FTTB, and HFC. For FTTP and HFC connections, connect the router directly to the NBN connection box. For FTTN and FTTB connections, you will need a separate VDSL modem or modem router upstream.
What is the difference between the Archer AX1800 and the Archer AX55?
The Archer AX55 offers higher AX3000 speeds, a faster processor, HE160 channel support on 5GHz, a USB 3.0 port, DFS support, and TP-Link HomeShield security. The AX1800 is the more affordable entry-level Wi-Fi 6 option — ideal for smaller homes or users upgrading from older routers on a budget. Choose the AX55 for maximum performance; choose the AX1800 for everyday home use at a lower price.
Does it support Wi-Fi 5 and older devices?
Yes. The Archer AX1800 is fully backwards compatible with Wi-Fi 5 (802.11ac), Wi-Fi 4 (802.11n), and all older Wi-Fi standards. All your existing devices will connect and work normally — Wi-Fi 6 devices will benefit from improved speeds and efficiency.
How do I set it up?
Download the free TP-Link Tether app on iOS or Android, connect to the router's default Wi-Fi network, and follow the in-app setup wizard. Most users are connected in under 5 minutes. You can also set it up via a web browser at tplinkwifi.net.
Can I use it with OneMesh extenders to cover a larger home?
Yes. The Archer AX1800 supports TP-Link OneMesh, allowing you to pair it with compatible TP-Link OneMesh extenders (such as the RE705X or RE505X) to create a seamless whole-home mesh network with a single Wi-Fi name. Devices automatically roam to the strongest signal as you move through your home.
