4G LTE Mobile Wi-Fi (and, importantly, USB) router

The device being viewed can connect tocellular network and distribute the Internet in several ways. The main one is to create a WiFi point for a mobile consumer group. At the cottage, on vacation, especially abroad, on a business trip, at a stand at the exhibition, etc. Everywhere where local opsos turn up access price tags and it’s more profitable to take one SIM card for the Internet for several consumers. The second way is to connect the laptop via USB as a 4G whistle. You can simultaneously distribute WiFi. Finally, after returning home, you can connect to your home router and configure it as a backup Internet channel in case of problems with the main one. Settings, tests, dismemberment. And I was especially surprised that the animal can work from external power with the battery removed.

I already thought my series about different variations of routers for the home was over, but no - today's hero deserves a separate review.

Instructions and equipment
1 X 4G Router
1 x USB charging cable
The box contains the following - acc in a separate bag, router, OTC card, manual only in Chinese (AAA battery - for scale)

The Chinese manual is noticeably annoying. At my request, the seller promptly sent an English version. However, I’ll clarify that in some details both the English and Chinese versions differ from the real device.
English manual

Battery



Appearance is a piece of white soap with lickedcorners and a black screen with bright icons. Aesthetic tension does not cause much delight - either. Below the inscription is silver paint 4GLTE. Between the inscription and the screen is a kind of small ellipse. The full feeling is that when turned on it should glow - but no, it does not glow, it does not have a functional purpose. Either the designer decided that it was so prettier, but rather atavism shone in the earlier version, then they decided - and so wonderful. (Later at autopsy I realized that I almost guessed)

The back face is empty, the upper and lower - too. On the left side is a microUSB port (and charging and data transfer) and a non-functional hole

If you remove the back cover - not far from thisholes there is a reset button. But to push it through this hole is impossible in principle. There is a microSD card slot between the hole and the charging port, but it is only available with the back cover removed
On the right side are the on / off and WPS buttons. A slot is also visible on the lower right-hand corner, making it easier to remove the back cover. You can remove-put with your bare hands.

When turned on, the icon first turns redbatteries at the top. After a few seconds, it changes color to purple. Then the cellular icon on the left lights up in red. It really doesn't mean anything. A cellular connection indicates the magenta color of this item. Following green, the WiFi icon on the bottom lights up. The right element is lit only when receiving and transmitting data over a cellular network.

All this resembles the extremely rich flag of South Africa. They also sought to fit more bright colors.

However - I find fault. Once figured out - no need to peer at the icons. According to the color drawing, a quick look reveals the condition of the device. So some sloppiness is justified functionally.
Mobile router can work asseparate device and in USB connection. In the latter case, firstly, with WiFi connected and disconnected. And secondly, you can connect via USB to a Windows computer, or, more interestingly, to a Linux router. We will consider all these options.
I strongly advise you to deal withtambourine sim card. I neglected this and lost a few hours. Since my ancient one, about 10 years old, Simka refused to work with the device. In addition, the router is imprisoned for the "big SIM", it is also miniSIM (2FF). My attempts to properly insert microSIM (3FF) into it failed.
SIM Dimensions

As a standalone device This is the simplest mode, it does not require any additional software and drivers, we’ll start with it.
Insert the sim card, the cut off corner in this picture right-up

We insert the battery, press the power button.
The battery icon turns red, thenpurple, then the cellular icon turns red (when the device connects to the opsos network, the cellular network icon turns crimson, but I had to configure it with my hands), then the WiFi icon turns green. Can connect via WiFi
Everything is written on the inside of the device, seeprevious photo - 4G network MFI_1DF (other numbers and letters at the end are possible), password 1234567890. If there is no cellular network yet, it will write that it is connected without the Internet.
Next, in the browser, go to IP 192.168.100.1, logs admin, password admin. (Then change all turnout passwords, of course)
I note the presence of the Reset button - forgotten settings can be reset to factory settings.

After entering the password we get into a simple andold-fashioned, but clear interface. This is the main screen. The blue arrows in a circle indicate the presence of cellular communications, the icons have the same meaning on the top right - the sim card is recognized, the network is there, we are not in roaming (the value of the last icon was not identified with certainty, probably WiFi)

Basic 4G settings, can be edited by hand

Basic WiFi settings. As you can see, simultaneous users default to 8. And more than 8 cannot be set, fewer can.

Status, main window

The word "basic" because most menu items have submenus falling out under the corresponding icon. But there is not much information, I did not take a screenshot so as not to overload the review.
As a USB device to a Windows PC, connect to a USB port - we have a device defined


and a virtual CD appears as follows

There is an ambush here. As it turned out, Setup hangs when you try to start directly from a virtual CD. But if you copy the application file to yourself on the SSD / HDD and run it from there, then everything is fine. I won’t be surprised if the application does not understand where Russian Windows has a temporary folder and tries to unzip files to its current location.
The setup launches an English-language wizard, installs drivers, Windows finds a variety of devices inside the modem



Additional Information

Setup installs a simple application, in this screenshot it is not yet connected either via 4G or WiFi

Displays status, can turn on and offWiFi point (leaving only USB connection), send USSD requests. And most importantly - if necessary, manually tune to a specific opsos. Moreover, it contains a library on the parameters of opsos from around the ball - Beeline in the Russian Federation and Kazakhstan, MTC in the Russian Federation, Belarus and many more where, including India. For some reason, the megaphone is designated as for the Far East. But in any case there is an editor, you can specify the parameters.
Additional Information

In this screenshot is connected
Further for verification through this modem I connected to the Internet - everything is fine, using standard Windows tools for creating a network connection.
A router with padavan firmware. Specifically, my router- the good old ASUS RT-N56U. But it’s not hardware that matters (with a USB port), firmware is important. For example, firmware from padavan Xiaomi Mi Router 3G 2.4 / 5 Wifi, Gigabit: exorcism session
For completeness - I have firmware 3.4.3.9-099
The mobile router is already configured, transferred to USB-dongle mode. We stick it in the USB port of a large router. We look at the end of the dmesg exhaust (This is not necessary, but curious!)

Then, almost immediately, this CD is turned off and the device reveals its true essence (idVendor = 05c6, idProduct = 6000) - a modem and a removable disk (in its role we have an SD card inside a mobile router).
By the way, these VID / PID are quite googled firewood and under Windows, which I did while dancing with a tambourine around a hanging utility when starting from the CD Setup utility.
To our sheep - great, you can connect.
Physically I chop off a WAN wire from a large router. The Internet is disappearing naturally. But the local network is working - I’m going to the webguy of a large router Advanced-> USB application-> Modem

Turn on and set the parameters - these worked (password also beeline)

We check the availability of the Internet - I load google.ru. At the first attempt, it didn’t work out for me, maybe I chose NDIS: LTE and other. In this mode, it was possible to select a provider, all the values ​​of the software set reasonable, but there is no Internet. It doesn’t matter, we go to the main page - we see that a USB modem has appeared

Click on it, he says that he is a RAS modem. Scored as above - it worked. I did not fight for maximum performance, obviously this is not in WCDMA - but I have a little traffic on the card, I postponed optimization experiments.
Speeds and signal strength Top to bottom - WiFi phone from a large router, cable internet
He is on a monitored mobile router
He is with the same SIM card inserted into the phone itself



I give for an example. I am aware that the speed of the mobile Internet is very much dependent on the opsos and on the point in space and time. So I don’t plan to run around Nerezinovsk and shoot digital in different places.
I put a mobile router on a cabinet next to myASUS (the latter I compared in terms of signal strength with Xiaomi Router 3G - almost parity). I look at the strength of the WiFi signal - in the same room, about 5 meters, in the next room, through a concrete wall, in the kitchen, through 2 concrete walls. My routers are highlighted with light green dots. I would say that the monitored router pleasantly surprised me.

Just in case, I’ll clarify that 5 GHz on the monitorThere is no router (there is one on my old man). Therefore, there will be no screenshots at 5GHz. And the air there is much cleaner, although they have already begun to foul. I looked now at all this riot and once again thought that when I re-glue the wallpaper I need to smoke about the Faraday cage with a mesh around the entire perimeter of the apartment
Inner World Under the back cover 6 pcs. screws, unscrew, carefully snap the latches, remove the front panel.
On the front cover is not enough interesting. Well, it can only be seen that the LED was really conceived in the center of the belly. And on the board under it there is a place, but not soldered. But if you look closely, you get the feeling that the LED was, but in a different version, with an LCD display. The possibility of which is indicated by unused contacts for the cable and harness.

Gray plastic is also not without interesting. These white perforated papers turned out to be foil antennas

But from the inside, the contact pads of these antennas are visible

Well, the main board on the reverse side. First impression - the designer did not know where to put so much space
The board is very clean, traces of flux are exactly whatfound with a microscope - but extremely insignificant. From the top left, next to the contact group of the standard antenna, I see something painfully similar to the RF connector for an external antenna.

This connector is larger, contact groups of standard antennas.


Another place for an unsoldered contact group

The only place (below in the frame) where I later, looking at photos from a microscope, found something resembling flux marks

Work from external power when removedbattery The very idea of ​​checking this mode occurred to me by chance. It was thought that if you connect it to the router and leave it for months on the backup channel, the battery will swell, they do not like this mode. I was surprised to find that everything works from USB charging with the battery removed. The only difference is that the battery icon does not light purple, but red.
But from a low-power 500 mA USB 2.0 port it does not start as it should. It seems to turn on, but there is not enough power to create a WiFi network. Still, 1 ampere is really needed.
Home - an old smartphone that distributes the Internet.
Only one advantage, but reinforced concrete - zero price. Therefore, most of this option is recommended.
There are also disadvantages.
- In the distribution mode, the smartphone runs out of battery. And she is also not young at the old smartphone. Therefore, you have to connect to the power. At one time or another - OK, with constant use, the battery may completely go awry.
- The smartphone has a lot of "excess". Services not needed by the router will consume resources, battery, and if configured incorrectly, it will also consume traffic.
- You can and can connect an old smartphone to the router as a backup channel, but I won’t take it
As a USB whistle, I also like the monitored piece of iron
- Has a built-in battery, that is, it can work with a low-power USB 2.0 port on the router. And some whistles have problems here, you have to use a USB hub with power.
- much more versatile
Advantages and disadvantages - Noname. Accordingly, new firmware should not be expected.
- Lack of detailed instructions. However, I managed to do everything like that.
- There is no LTE Band 20, not used in China, but involved with us. The disadvantage is significant, but not lethal, we also use other bands for LTE
- Does not know how to send SMS messages (but can do USSD commands)
- The SD card inserted in the router can only be used in a USB connection
- A small jamb of regular software - setup must be copied to a local disk before starting
+ Work out the declared functionality and WiFi router and USB whistle
+ Unlike operator devices, it suits any opsos without file modification
+ Mobile, with 2400mAh battery
+ Amazingly, when connected to external power, it works even with the battery removed.
+ Lightweight, 152 g, of which the majority is a battery. And compact.
+ Wide range of 4G / 3G / 2G cellular protocols
+ In a USB connection it can send USSD commands to set the tariff (but does not know how to SMS)
+ Indication by several multi-colored LEDs is simple and clear, no need to peer at the letters on the screen
+ Not badly made, there are opportunities for improvement
TotalAn average user without such a device inMost of the cost. Internet on kraynyak can be handed out from a mobile phone. You can do without a backup channel at home, limiting yourself to a browser in the same mobile. Not every day the provider has problems ... But if the tasks that the monitored animal can solve are at least sometimes relevant for you, it solves them with dignity. Able to pay for one trip with a family abroad on vacation, during an exhibition, etc. And then seriously save your nerves if the wired Internet is down, and you urgently need.
