TP-Link TL-MR6400 3G / 4G LTE Wi-Fi router review

To organize access to the Internet through a mobile operator’s network, now you do not need to buy a modem, select a router for it, or use your smartphone as a modem in modem mode (which is not very convenient and not always possible). We only need a TP-Link TL-MR6400 router and a SIM card for any operator. And in a few minutes we can get fast internet on all our devices, where there is 3G / 4G coverage.

TP-Link TL-MR6400 is a conventional fixed router, but with an integrated 3G / 4G modem and a SIM card slot. And it’s very convenient. You can not connect a wired Internet anywhere. Especially in villages, in the country, etc.

There are many places where the only way to connect to the Internet is a 3G / 4G network of one or more operators. And if earlier we needed to buy a USB modem for a SIM card of a certain operator and look for a router that will work with this modem now it is possible to install TP-Link TL-MR6400 and just insert a SIM card into it.

After that we can connect to the Internet devices on the Wi-Fi network and using a network cable. Depending on the operators (coverage) available in your region and your tasks, you can choose the appropriate tariff and purchase a separate SIM-card specifically for the router.

Specifications for the TP-Link TL-MR6400 are the most common. Wi-Fi network router distributes at speeds up to 300 Mbps. There are 3 LAN ports and 1 LAN / WAN port. And this means that the router is able to work not only with a SIM card, but also as a normal router with a WAN-port Ethernet (you can change the mode of operation).

For some reason, everyone writes that external antennas are used to receive a 4G signal. And Wi-Fi antennas are built-in. But on the official website, in the characteristics of the TL-MR6400 v3, the reverse is true: 2 built-in 4G LTE antennas and 2 external Wi-Fi antennas. I do not know how it actually is, but the 3G / 4G signal reception from the router is better than the smartphone.

The setting is very simple. I did not even set up an internet connection. Simply inserted a SIM card, turned on the router and he immediately began to distribute the Internet. You just need to set a password to protect the control panel of the router and set the Wi-Fi network settings (not necessarily, but desirable). Settings in English, but to understand them is not difficult. The control panel is new (in blue tones).

Already, by tradition, start with the box.

Inside is the router itself, the power adapter, the network cable and various pieces of paper. Everything is well and securely packed.

Glossy plastic is beautiful. But the black glossy plastic, from which the lid of this router is made, very much collects fingerprints. Well, the dust on it is very noticeable. The bottom of the router is made of matte plastic. Above is the relief logo of TP-Link. Below are the indicators that can be seen only when the router is turned on. They are lit in blue.

Bottom of all the standard – holes for cooling, holes that allow you to hang the router on the wall and a sticker with factory information.

All ports, connectors and buttons are located behind the router. There we have a power connector, 4 LAN ports (one of them works like a WAN), a POWER ON / OFF button, a separate button to turn off and turn on Wi-Fi and a WPS / Reset button. Well, the most interesting – a slot for SIM-card format micro-SIM.

On other sites I saw information that the antennas are removable. But this is not so. I do not know, maybe it depends on the hardware version. Let me remind you that I have TL-MR6400 v3.

How does the TL-MR6400 work with a SIM card?

I just inserted the operator’s SIM card in the slot (new card, 4G) and the router immediately started distributing the Internet. Three indicators indicate the level of the signal. In my case, it was the maximum. On the phone in this place the signal is not maximum. Hence the reception of the router is the best.

The control panel displays detailed information on the connection to the mobile network. Network mode (3G / 4G), signal strength, connection status, and so on.
The incoming speed is 47 Mbps. But as I understand, this is far from the maximum speed. I saw feedback that you can squeeze 70-80 Mbit / s and even more. I think a lot depends on the operator, the signal level, the base station.

The conclusions:

If you have the opportunity to conduct normal cable Internet – conduct. In this case, this router is not very suitable for you. There is no point in overpaying for a functional that you will not use. If in your home, at work, etc., you can connect only the mobile Internet, the TP-Link TL-MR6400 is an excellent solution.
