Internet without a fixed line.
The 4G LTE modem reaches up to 150 Mbps down and 50 Mbps up and covers the Australian 4G bands. Wi-Fi is 2.4 GHz N300, which gets through walls well and suits browsing, streaming, EFTPOS and a few cameras. Real 4G speed depends on your carrier and the signal at the site.

Back
Two ports and two antenna sockets.
The back has a power socket, a LAN/WAN port, a LAN port and the Reset/WPS button. The two round sockets at the top take an external 4G antenna if the signal inside is weak.

Ports
Use it with or without NBN.
Plug the LAN/WAN port into an NBN or other modem and the TL-MR105 works as a normal router, with 4G as a backup connection. Both ports are 10/100 Mbps.

In the box
Router, power and cable.
TP-Link includes the router, a 9 V power adapter, an Ethernet cable and a quick installation guide. Set it up from a browser or the TP-Link Tether app.
How it goes in
From SIM to Wi-Fi in minutes.
01
Check the signal
Check 4G signal on a phone with the same carrier where the router will sit. Near a window is usually best.
02
Insert the SIM
With the power off, put the nano SIM in the SIM slot, then plug in the power adapter.
03
Connect
Join the Wi-Fi name printed on the label, or plug a computer into a LAN port with the included cable.
04
Set it up
Open the web page or the TP-Link Tether app, enter your carrier's APN if asked, and set your own Wi-Fi name and password.

Common questions
Is a SIM card included?
No. Use a nano SIM with a 4G data plan from your carrier.
Which carriers does it work with?
It covers LTE FDD bands 1, 3, 5, 7, 8, 20 and 28 and TDD bands 38, 40 and 41, the bands used for 4G in Australia. Check your carrier's coverage where it will sit.
How fast is it?
Up to 150 Mbps down and 50 Mbps up on 4G, and up to 300 Mbps Wi-Fi on 2.4 GHz. Real speed depends on your carrier and signal.
Does it support 5G?
No. It is 4G LTE. The 3G bands are listed on the datasheet, but Australian 3G networks have closed.
Does it have 5 GHz Wi-Fi?
No. Wi-Fi is 2.4 GHz only (802.11b/g/n, up to 300 Mbps).
How many devices can connect?
TP-Link quotes up to 32 Wi-Fi devices.
Can I add an external antenna?
Yes. It has two external antenna ports for a 4G antenna, sold separately. Confirm with us which antenna suits your site.
Can I use it with NBN?
Yes. Plug the LAN/WAN port into the NBN or other modem and it works as a wireless router, with 4G as a backup.
Can it go outside?
No. It is an indoor router rated 0 °C to 40 °C. For outdoors, look at the ER703WP-4G-Outdoor.
How do I set it up?
From a browser or the TP-Link Tether app. Insert the SIM, power it on, join the Wi-Fi on the label and follow the quick setup.
Does it have parental controls?
Yes. It has parental controls to block websites and set time limits, plus a 2.4 GHz guest network.
Are the ports Gigabit?
No. Both Ethernet ports are 10/100 Mbps, which is above the 4G speed it can reach.

Installation and safety
Low-voltage device. Runs from the 9 V 0.85 A adapter in the box. The adapter plugs into mains power; keep both dry and indoors.
Placement. Indoor use only, 0 °C to 40 °C. Keep the vents clear and away from heat sources.
External antennas. An outdoor 4G antenna on a roof is work at height and needs proper earthing. Use a licensed installer.
What it does not do. No 5G, no 5 GHz Wi-Fi, no Gigabit ports, and no SIM or external antennas in the box.
