Description
Outdoor 4G LTE Connectivity for Homes and Businesses Across Australia
The TP-Link Archer MR402 is a purpose-built outdoor 4G LTE Cat 6 router designed to capture the strongest available mobile signal and deliver reliable fixed wireless internet to homes, businesses, and remote properties across Australia. Housed in a weatherproof IP65-rated enclosure and powered via a single PoE cable, it mounts directly outdoors — closer to the cell tower signal — for significantly better reception than any indoor router can achieve.
Whether you’re in a regional area beyond the NBN fixed-line footprint, or simply looking for a more reliable broadband alternative, the Archer MR402 is a straightforward, installer-friendly solution that works with any Australian 4G carrier.
Key Features
- 4G LTE Cat 6 modem — download speeds up to 300 Mbps, upload up to 50 Mbps
- 3G fallback for continuous connectivity in areas with limited 4G coverage
- Dual-band AC1200 Wi-Fi: 300 Mbps (2.4 GHz) + 867 Mbps (5 GHz)
- IP65-rated weatherproof enclosure — dust and water resistant for permanent outdoor installation
- PoE-powered via included PoE injector — single cable carries data and power
- Built-in directional antenna array for enhanced 4G signal capture
- Nano SIM card slot — compatible with all Australian 4G carriers
- 1× Gigabit Ethernet port for wired connection to indoor router or switch
- Router mode and bridge mode support for flexible network integration
- Signal strength LED indicator for optimal mounting position
- Easy setup and management via the Tether app (iOS & Android)
Use Cases
-
Regional & Rural Australia: Ideal for properties beyond the NBN fixed-line footprint where 4G LTE is the best available broadband option. Outdoor mounting maximises signal capture from distant cell towers.
-
NBN Alternative: Replace slow or unreliable fixed-line NBN with a fast 4G connection, particularly in areas with strong Telstra, Optus, or TPG 4G coverage.
-
Farms & Large Properties: Mount on a shed, silo, or outbuilding to capture the best available 4G signal and distribute Wi-Fi across the property via the indoor network.
-
Construction & Temporary Sites: Deploy fast internet quickly at job sites or temporary offices without waiting for fixed-line installation.
-
Business Continuity / WAN Failover: Use as a secondary WAN connection to keep operations running if your primary fixed-line service goes down.
-
Caravans & Cabins: Permanently mount at a holiday property or cabin for reliable seasonal internet access without a fixed-line contract.

Frequently Asked Questions
Does the Archer MR402 work with Australian 4G networks?
Yes. The Archer MR402 supports 4G LTE bands used by Australian carriers including Telstra, Optus, and TPG/Vodafone. It accepts a standard nano SIM card — simply insert your SIM and the router will connect automatically. Check your carrier’s 4G coverage map to confirm signal availability at your location before purchasing.
How is the Archer MR402 powered?
The MR402 is powered via PoE (802.3af) using the included PoE injector. A single Ethernet cable runs from the indoor PoE injector to the outdoor unit, carrying both data and power. No separate power cable is required at the mounting point, making installation clean and straightforward.
How far can the Ethernet cable run between the MR402 and the PoE injector?
Standard PoE over Ethernet supports cable runs up to 100 metres. Use outdoor-rated, UV-resistant Cat5e or Cat6 cable for any exposed sections of the run.
Can I use the MR402 in bridge mode with my existing router?
Yes. In bridge mode, the MR402 acts as a 4G modem and passes the connection through to your existing indoor router, which handles DHCP, firewall, and Wi-Fi. This is ideal for integrating 4G into an existing network without replacing your current setup.
Why mount the router outdoors rather than using an indoor 4G router?
Outdoor mounting places the antenna array as close as possible to the 4G signal source, without walls, roofing materials, or building insulation attenuating the signal. In regional and fringe-coverage areas, this can make the difference between a marginal, unreliable connection and a fast, stable one.
Is the Archer MR402 suitable for permanent outdoor installation in Australia?
Yes. The IP65 rating protects against dust ingress and water jets, and the operating temperature range of -40°C to 65°C covers the full range of Australian climate conditions — from alpine winters to outback summers. It is designed for permanent, year-round outdoor installation.
