Reliable 4G LTE Internet for Homes and Small Offices
The TP-Link Archer MR402 is a dual-band AC1200 4G LTE router that delivers reliable fixed wireless internet to homes and small offices across Australia. SIM-unlocked and compatible with all major AU carriers, it is a straightforward and affordable solution for properties where NBN is unavailable, unreliable, or awaiting connection.
Description
The Archer MR402 combines a 4G LTE Category 6 modem with dual-band AC1200 Wi-Fi 5, providing download speeds of up to 300 Mbps on compatible 4G networks. Four Gigabit LAN ports allow wired connections for smart TVs, desktop PCs, gaming consoles, and NAS devices, while two external TS-9 antenna ports enable connection of high-gain antennas to improve signal reception in low-coverage or rural areas.
Setup is handled through the TP-Link Tether app or a standard web browser. The Archer MR402 supports automatic 3G fallback when 4G is unavailable, ensuring continuous connectivity across Australia’s mobile network footprint. It is well suited to households and small businesses looking for a cost-effective 4G fixed wireless solution without the complexity of a separate modem and router.

Frequently Asked Questions
- Which Australian carriers are compatible with the Archer MR402?
- The Archer MR402 is SIM-unlocked and compatible with all major Australian 4G carriers including Telstra, Optus, and Vodafone, as well as MVNOs operating on these networks. Check the TP-Link AU spec page for the full LTE band list and verify with your carrier that the supported bands match your area before purchase.
- Can I connect an external antenna to improve 4G signal?
- Yes. The Archer MR402 includes two TS-9 antenna ports, allowing connection of compatible external LTE antennas such as directional Yagi or omni-directional antennas. This is particularly effective in rural or fringe-coverage areas where the internal antennas cannot maintain a reliable connection.
- What is the difference between the Archer MR402 and the Archer MX700?
- The Archer MR402 is a 4G LTE router suited to standard broadband use, with AC1200 Wi-Fi 5 and Gigabit LAN. The Archer MX700 is a 5G router with significantly higher download speeds, AX6000 Wi-Fi 6, a 2.5G LAN port, and a 10G WAN port — suited to power users in 5G coverage areas. Choose the MR402 for cost-effective 4G connectivity; choose the MX700 where 5G is available and higher performance is required.
- Does the Archer MR402 support 5G?
- No. The Archer MR402 is a 4G LTE Category 6 router and does not support 5G networks. For 5G fixed wireless connectivity, consider the TP-Link Archer MX700 or Archer NX600.
- Can the Archer MR402 be used as a backup internet connection?
- Yes. The Archer MR402 can be used as a standalone 4G internet connection or as a backup to a fixed-line NBN service. Note that automatic WAN failover between a fixed-line connection and the 4G SIM is not a standard feature — check the latest firmware release notes on the TP-Link AU support page for current failover capabilities.
