This article will focus on the TL-MR3420 router and its compatibility with USB modems from different operators in Ukraine and Russia. The main problem is that TP-Link TL-MR3420 (like any other router) may not work with all modems and carriers. And before buying this router, be sure to check it for compatibility with your modem. Better yet, choose a modem from the list of compatible modem specifically for this router. (if you are planning to buy it, or have already bought it)... It may turn out that after purchasing, connecting the modem and setting up, the router simply does not see the modem, or it refuses to connect to the Internet.

How to check if the modem is compatible with TP-Link TL-MR3420?

TP-Link's official website has a list of compatible modems specifically for this router. Everything is very confusing there. I will now show you how to view these lists. They are different for Ukraine and Russia.

An important point! If the modem is in the list of compatible, then there is no 100% guarantee that everything will work. I already wrote above that a lot depends on the firmware and hardware version. Yes, and modem firmware can change.

But if the modem is not in the list of compatible, this does not mean that it is not supported by TL-MR3420. It's just that this modem was not tested by TP-Link.

1 As I understand it, to check modems Ukrainian operators you need to follow the link http://www.tp-link.ua/ru/download/TL-MR3420_V2.html#Compatibility, select your hardware version of the router (it is indicated at the bottom of the router itself, if you have not bought it yet, you can check with the sellers which hardware version they have)... Next, on the "Compatibility" tab, click on the link "List of compatible 3G / 3.75G USB modems".

We save the file to the computer, open it via Excel and look for the necessary modem in the list.

2 If you have modem Russian operator , then follow the link http://www.tp-linkru.com/download/TL-MR3420_V2.html#Compatibility. In the same way, having selected the hardware version of the router, on the "Compatibility" tab, follow the link.

A list of compatible modems will open. Where the model of the modem, operator, etc. is indicated. Also carefully read the information that is at the beginning of the page.

What modems exactly does it work with?

Works exactly with Verizon USB720. This is the Ukrainian provider Intertelecom. Should also work with Huawei EC 306.

Models I found in reviews (cannot guarantee compatibility): Verizon UM150-VW, LGVL600, HUAWEI E1550, SIERRA598U, PANTECH UM-185, HUAWEI E352, Novatel U760, Pantech UM190, Pantech UM150.

In fact, TP-Link TL-MR3420 supports a lot of modems.

How to set up TP-Link TL-MR3420 with 3G / 4G USB modem?

Very simple. I wrote about this in the article:. Everything is the same there.

Brief instruction on the example of TL-MR3420:

We turn on the router. We connect a USB modem to it. We connect by network cable, or via WiFi from the device from which we will configure.

We go to. Or according to the instructions.

In the "Network" (WAN) - "3G / 4G" section, we look to see if the router has detected our modem, then select the country, operator and connect to the Internet. If the connection is established, then we save the settings.

If the provider is not in the list, then the number, username and password are set manually.

What if TP-Link TL-MR3420 does not detect the modem and does not connect to the Internet?

There are many options, consider the most popular:

1. If you connect the modem via a USB extension cable, connect it directly. Without extension cord.
2. Update the firmware of the TL-MR3420 router. If you have updated, and the modem is not exactly detected, then try installing a different firmware. Even older. This helps a lot.
3. Write to TP-Link support. Describe everything in detail. Specify the hardware version of the router, modem model, operator. Perhaps they will tell you which firmware to install, or they will send you a bin file for your modem.
4. If the modem is detected, but there is no Internet connection, then first check if there is a modem connection from the computer. Make sure you have specified the correct parameters in the router settings. And is there coverage of your carrier in the place where the router is installed.

That's all. In the comments, you can ask your questions, and of course shares useful information about this router. Hope you got it set up and everything works great. Best wishes!

One of the routers that I was expecting for the test is TP-LINK TL-MR3420... The interest is primarily associated with the regular use of 3G / 4G modems from Russian cellular operators... Having made the decision to move away from the hustle and bustle of the city and faceless high-rise buildings, with all the advantages of living in my house, I also received a minus in the form of the inability to connect to a cable operator.

This material is a continuation of acquaintance with the company's products, previously you could already familiarize yourself with TP-LINK TL-WR2543ND, and TP-LINK TL-SC4171G.
The use and advantage of a router for distributing 3G / 4G at home is obvious, this is the versatility in finding the optimal location for the modem, eliminating interference and, of course, distributing to several devices at once. About two years ago, I started using the solution - Zyxel Keentic 4G, this router is still used today to organize a home network. TP-LINK TL-MR3420 interested, in turn, with better characteristics at a cost that is almost half less. What he can actually offer, let's see the results of the extended test below.

TP-LINK TL-MR3420 Availability

At the time of this writing, the average cost per TP-LINK TL-MR3420 according to Yandex.Market, it is 1190 rubles. The price is attractive considering that the prices for the distribution models offered by the operators mobile internet Wi-Fi, above.

Among the competitive solutions, the following models can be noted: ZyXEL Keenetic 4G (1920 rubles), Upvel UR-344AN4G (1120 rubles), Huawei AF23 (1631 rubles). Judging by the current offers on the Russian market, TP-LINK TL-MR3420 is the most affordable 3G / 4G Wi-Fi router.

Inside the package except for the TP-LINK TL-MR3420 found two detachable antennas, a power supply, a patch cord and a set of brochures, instructions and manufacturer's warranties.

There is everything you need to get started. The only thing missing is a USB-HOST extension cable for attaching the modem remotely from the router. This approach makes it possible to make the installation possibilities of the modem wider, it may be optimal to install the modem on glass, this will reduce interference from the router itself, as well as improve the signal reception level.

TP-LINK TL-MR3420 design

Considered TP-LINK TL-MR3420 is the second version of this model. The manufacturer has updated appearance, added support for 4G, the hardware was partially updated.

Externally, the router has become more stylish thanks to its smooth shapes.

The dimensions of the device are compact, the main body material is white plastic.

The bottom of the router is made of matte gray plastic.

There are slots at the junction of the two parts for heat dissipation during operation.

On the front side TP-LINK TL-MR3420 there is a gray plastic insert. It houses a row of green backlit LEDs.

These are indicators of power, network status, connection activity, modem activity, QSS mode.

There is an information decal on the bottom surface. It housed serial number, MAC address, IP address and data for authorization to the web interface.

There are also two T-cutouts for wall mounting. There are no self-tapping screws in the kit.

On the back wall there are: antenna jacks, 1 x WAN and 4 xLAN ports, a power socket, a WPS activation and power button.

A USB 2.0 port for connecting modems is brought out to the side. Next to it is a recessed reset button.

Filling TP-LINK TL-MR3420

For us, the internal content is often much more interesting than the external appearance. Let's see what is hidden inside TP-LINK TL-MR3420... The two halves are fastened together with two screws.

The basis of the router is a board built on a chip Atheros AR9341(the first version used AR7241).

The low heat dissipation of this chip made it possible to get rid of the cooling heatsink. And also improved the overall performance of the router. Atheros AR9341 includes 500 MHz processor(against 400 in the previous build) and interfaces, including USB 2.0 with support for external 3G / 4G modems.

The budget of the model is reflected in the lack of shielding on the microcircuits, although in general it should be noted right away that this is not critical at home.

RAM is implemented using Zentel A3S56D40FTP, 32 MB of RAM is available.

Flash memory is implemented using the SPANSION chip, 4MB available.

There are no complaints about the quality of soldering, everything was done carefully and thoughtfully.
