  1. HUAWEI 4G Dongle E3372 is a compact and user-friendly designed 4G Wi-Fi dongle. This device supports the category 4 LTE, which allows you to enjoy faster download and data transfer rates.
  2. HOWTO use a Huawei E3372 on OpenWRT. This modem is also sold as a MegaFon M150-2 USB dongle. Needed Software. Install the needed packages via opkg tool. Opkg update opkg install kmod-usb-net-cdc-ether opkg install usb-modeswitch.
  3. It appears that Huawei E3372 frequently disconnects from the LTE network for no apparent reason. It wouldn't be much of a problem if it managed to quickly and reliably reconnect, but that isn't the case it would seem. Whenever that happens packets get lost and websites don't load properly, and overall internet experience is well below acceptable.

  5. I have the same problem like @DanielTheFreak with conection of Huawei E3372 to the TL-MR3020. The country is Romania service provider Telekome. Can you help me with the firmware for huawei E3372. The mentionated link is not working anymore.

The Huawei E3372 is quite a popular LTE stick: it’s widely available (in retail stores, on eBay and also in branded variations, eg. “Telekom Speedstick V”, “Megafon M150-2”) and rather affordable (currently starting at €60 in Germany). It features a LTE Cat 4 modem supporting up to 150 MBit/s download and up to 50 MBit/s upload speeds, falls back to (DC-)HSPA(+), UMTS and EDGE, if necessary, and has quite small dimensions (88m x 28mm x 11.5mm).

The bad news is that the E3372 comes in one of two variants:

  • with a “Hilink” firmware (version numbers 22.x) the stick appears to the USB host as an Ethernet device, runs an own DHCP server and provides a Web interface at the IP address 192.168.8.1 to control its router operation. This also means it will do the network address translation (NAT) for you and has some sort of firewall, which, at least in the version I had (see below) was not configurable at all. Sticks that come with the Hilink firmware seem to carry the model code E3372h-xxx.
  • with a “Stick” firmware (version numbers 21.x) the stick appears to the USB host with two USB serial devices one of which exposes an AT-style interface over which both PPP (slow) and NCM (Network Control Model, part of the USB implementers forum Communications Device Class (CDC) class of protocols for providing Ethernet-over-USB style networking, faster) modes can be employed. In this mode the interface created exposes the IP address assigned by the mobile network directly, ie. there is no NAT. Sticks that come with the stick firmware seem to carry the model code E3372s-xxx (but see below).

Hilink mode is practical for most users because they likely need no special drivers to use the LTE stick but it’s disadvantageous if you want to provide services to the Internet. Unfortunately you can’t see from the outside whether you get a E3372h or a E3372s unless you can slide the stick’s cap off to access the SIM slot (see the gallery). It is, luckily, possible to flash a stick with the respective opposite kind of firmware, eg. a Hilink firmware stick with a Stick firmware and vice versa. However this process can get a bit cumbersome as quite a lot of information on the Web is incomplete, outdated or in a foreign language.

The stick I bought carried the following version information:

Model codeE3372h-153 E3372h: Apparantly sold with Hilink firmware, E3372s: Apparantly sold with stick firmware (but see below)
E3372x-yyy: Apparantly a region-specific code, couldn’t find its exact meaning however
Hardware versionCL2E3372HMThe HM indicate it’s a E3372h whereas SM would mean it’s a E3372s.
Software version22.200.15.02.1217All Hilink firmwares use a 22.x version number.
Web UI version17.100.12.01.1217The Web UI gets flashed separately from the Hilink firmware (first the Web UI, then the Hilink firmware). With a stick firmware the Web UI is inactive.

Note that my stick wasn’t SIM-locked or anything and I didn’t flash from stick to Hilink firmware, so I didn’t need an unlock code or something like that.

What did NOT work for me

  • Instructions that report that mode switching would be a simple as accessing an URL such as http://192.168.8.1/html/switchProjectMode.html. As this finnish blog post points out, this appears to have worked with older E3372s versions only. Note that this seems to imply that there were E3372s versions with Hilink firmware, too.
  • Sending a specially crafted XML packet to the Hilink API as described in Ivan’s post gave me just a pretty useless error message.
  • Flashing under Windows 10. Something changed in between 7 and 10 that hinders almost all flashing tutorials given. I had to explicitly install Windows 7 on a spare SSD to get further (but then flashing didn’t work for other reasons). Your mileage may vary.
  • The flash instructions given eg. in said blog post and others such as in the widely distributed E3372h-Nadelmethode-mmtk.rar (involving Huawei official .exe files) and those given in this internet-sim.at blog post (using a Huawei_Flasher_v2.exe) did not work either. I kept receiving Code 13 error messages.

What worked for me

Following the first four steps from this lteforum.at post, which have the advantage that they work without a Windows installation as well:

  1. I cloned the forth32/balong-usbdload and forth32/balongflash repos from Github and compiled the software (which is pretty easy, given it has no special requirements).
  2. I physically opened the LTE stick and used the “needle method” as demonstrated in this YouTube video by a clever Russian: you effectively shorten a test point of the stick’s PCB to Ground when plugging the stick into the USB port which seems to put it into some special bootloader mode. Watch Windows’ device manager resp. syslog for a newly detected USB serial port.
  3. I then used the balong-usbdload utility to put the stick into a special, non-persistent download mode (note the use of sudo, the balong utilities need to run as root): sudo balong-usbdload -p /dev/ttyUSB0 usblsafe-3372h.bin. Of course you need to use the right ttyUSBX device (try lsusb, e.g. it might be ttyUSB1 or ttyUSB2 in your case).
  4. Afterwards I could flash the stick firmware with balong_flash: sudo balong_flash -p /dev/ttyUSB0 3372h-153_UPDATE_21.180.01.00.00.BIN (taken from this a bit confusing lteforum.at page, look for the link “E3372h-153 21.180.01.00.00 general”). Note that the actual ttyUSBX device might have changed from the previous step, I’ve been told the balong-usbload utility might interfere here.

And that’s it! Note that I didn’t select that particular stick firmware version intentionally. I haven’t found a changelog of some kind between the different firmware revisions yet.

Those who want to buy a date LTE stick, will certainly choose the Huawei E3372. The stick is very convenient to get on the Internet. Since the Huawei E3372 was launched in the 2014 Autumn, there has been no review for this new LTE Stick. In recent years, Huawei has brought few new LTE sticks monthly on the market and I thought more interesting models with LTE Advanced Cat6 will surely come on the market soon. Here we already have the LTE router Huawei E5786 and the Huawei E5186.

Now I had the opportunity to test the Huawei E3372 and see more details. The full report of LTE stick test is in this article.

Appearance
As I have already indicated in my introduction, there is no special feature on the Huawei E3372 LTE stick. However, in comparison with older devices, the E3372 is a low-cost model. Huawei is likely to have very low production costs and the LTE stick is also available at very reasonable prices. The direct predecessor Huawei E3276 (also known as Telekom Speed Stick LTEIII), for example, had the similar technical data as the E3372, but E3276 has a rotatable USB port, which was very convenient. The E3372 has a compact design and also has its own advantages.

The Huawei E3372 is made entirely of plastic, but looks quite stable. No accessories are included with the stick. Only a Quick-Start Guide and Safety Instructions are hidden in the little box.

LTE Cat4 Modem
The modem in the Huawei E3372 allows speeds of up to 150 MBit/s for the downlink and up to 50 Mbit/s for the uplink based on LTE category 4. In the test, I have achieved approximately just 140 MBit/s for download. The latencies were under 20 milliseconds in the LTE network. In the uplink, I could reach about 40 Mbit/s. Of course, the data rate will vary depending on usage and reception situation.

Of course, the Huawei E3372 can also work with UMTS networks including DC-HSPA+ with up to 42.2 Mbit/s in the downlink and 5.76 Mbit/s in the uplink when LTE network is not available. And the GSM and EDGE networks are supported. The LTE modem could support the frequency ranges of 800, 900, 1800, 2100 and 2600 megahertz (both FDD LTE), making it well suited for use in Europe. If you use it in America, it can be only conditionally recommended. In UMTS, it supports dual band (900/2100MHz) and in GSM supports Quadband.

If you want to improve reception and data rates, Huawei E3372 could connect an external antenna. Under two covers, there are two CRC-9 ports available to fasten a MIMO antenna. Below is the suitable antenna for Huawei E3372 recommended.

Appliances and Software
The Huawei E3372 is designed to operate on the notebook or desktop PC. User just need plug the LTE stick to a free USB port. After a brief driver installation, the drive already connects to the Internet. The connect software does not need be installed due to “Huawei HiLink”. The complete operation and configuration is performed via the browser, just as you would know from an ordinary DSL router or a MiFi router .The Huawei E3372 automatically recognizes the operator based on the inserted SIM card and takes an appropriate configuration ahead, so you make no further settings.

To operate the Huawei E3372, you need a standard mini SIM card in 2FF format, which is currently the largest available SIM-card format. Micro or nano-SIM card with an adapter to go but also easily and adapter can cause the stick no harm. By the way, users can also insert a microSD memory card and use the E3372 as USB memory stick.

Operating the Router
The Huawei E3372 LTE Stick can basically be operated on a wide variety of router models. Here it is important to distinguish: I have tested in my test version “E3372h-153“, which works significantly less router models than the version “E3372s-153“. So small differences exist between h and s. I was able to operate my E3372h successfully with the Dovado Tiny AC and a Dovado GO. With AVM Fritzbox 7490, the stick did not work.

Telekom Speed Stick LTE V
Telekom also offers the Huawei E3372 for about a year, named “TelekomSpeed Stick LTEV”. It is the 5th generation LTE stick at Telekom as the name suggests.

Conclusion
The Huawei E3372 is no doubt a good LTE Stick! Although it doesn’t support current LTE Advanced Cat6 technology for very high data rates, the LTE Cat4 modem makes the stick cut a good figure. The receive and transmit performance is well above average and the latency satisfyingly low. Actually, there is no LTE cat6 stick available now.
