Huawei CarFi E8377 LTE Router Review

In the last few years, it’s the main trend to connect cars. Internet access in the car or camping Mobile is still reserved for the premium class. However, new wireless gadgets provide solution. The Huawei E8377 specially designed for the motor vehicle provides the first use and inexpensive hotspot router with LTE. We have tested the “Huawei Carfì Router” for you and share the details below.


With the Carfì E8377 router, user can access internet via the mobile Wi-Fi hotspot. The CarFi could work on 3G or 4G LTE and up to 150 Mbits per second download speed are possible here. The concept is not entirely new. Huawei had brought a car Stick named W5101 for the first time to the market. It’s available for Vodafone contract. But it’s an ordinary USB stick, which was connected via an adapter into the cigarette lighter. The E8377 Carfì could connect to the card through the cigarette power connector, which is a direct solution for wireless network.

The packaging looks quite classy and looks like a clock-bell. After opening the box, there is only a mini-manual next to the device. In addition, a tiny leaflet-list is available for installation. The user manual (sweet 6.5 x 5 cm) available in several languages and there are short Tips for settings.

The egg-shaped head of CarFi E8377 gives only a start switch, a notification LED and laterally a SIM card slot (Micro SIM) together with the reset button. Directly to the head connects to the cigarette 12-volt port. From a processing perspective, the device is “appropriate”. The specially adapted to use in the car shape design, the E8377 hardly looks like a foreign body in any case.

Now, let’s consider technical data. The mobile module initially supports LTE in all major bands at 800, 900, 1800, 2100 and 2600 MHz. Thus, the Car-stick can easily use in Europe. Based on the LTE Cat4 modem, it can reach up to 150 Mbps for download and up to 50 MBit for upload in connection with a matching LTE tariff. In addition to LTE/4G, the CarFi still has support for more mobile phone standards. Among them are as UMTS 900 and 2100 MHz 3G Turbo DC-HSPA+ (up to 42 Mbps) and 2G (GSM, EDGE, GPRS). So even in very poor regions with weak signal, user can still have the chance of a slow connection. The WLAN module supports 802.11 b/g/n and thus can provides data rates up to 300 Mbps.


The router Carfì measures 5.9 x 4.9 x 8.8 inches and weighs only 50 grams according to the manufacturer. However, our weight measurement yielded 146 grams. Huawei will also indicate that the E8377 has an integrated battery, which has a capacity of 1900 mAh. However, we were able to connect Carstick for long hours of use on the current port, without connecting the CarFi to the cigarette slots. Thus, we believe that the battery only serves to maintain the operation as soon as the energy source is gone suddenly.


A USB port is located on the side. This port is not a data interface, but as a kind of adapter. Huawei has considered that many people use the car’s cigarette lighter as a charging station for mobile phones and other devices, when the cigarette port is used. No more space will be available without adapter for third-party devices. Through the USB port on the side, you can now connect there and load it. Beside the SIM slot, there is a TS9 connector for connecting an external antenna. However, only 1 port, users have to give up 2×2 MIMO. But at least there is a possibility! It is precisely when traveling, for example with a camper, the reception is weak and need external antenna.

To make user understand well about the color shining in Huawei CarFi, here are some codes about the colors:

  • * Flashes red: Indicates that the Carfì is started. Takes about 20 seconds;
  • * a steady red light: Indicates that no wireless network is found, or the connection was not possible (eg missing SIM);
  • * lights up yellow: Indicates that the signal strength for 3G or LTE is very weak;
  • * green: reception strength is optimal;
  • * Flashing cyan: There is just a firmware update;
  • * White: Indicates unread SMS exist.

Installation and Settings

Theoretically, the installation of the E8377 is easy and should be done in less than 3 minutes. First, the SIM card must be inserted. The slot is located under a cover with SIM icon. Then plug the Carfì directly into the cigarette lighter of your car. Turn the ignition so that a power supply is present and press the “Huawei” button on the top for a good 3 seconds. Now the border should first turn red – the CarFi router will start and automatically connects to the wireless network. This takes about 20 seconds. Now you can search the wireless SSID of CarFi E8377 in a laptop, tablet or smartphone. This begins with “Huawei CarFi-“. Both SSID and the wifi key are listed at the foot of the plug. Enter this key or scan the QR code on request with your smartphone. The WLAN connection to Carstick should now be finished. If there is a cellular connection via 2G / 3G or 4G, surfing internet is possible in the way. And up to 10 devices in and around the car could access to the internet.


Huawei provides a special HiLink App for smartphone and tablet users. This can (if no network) are downloaded directly to the internal memory as required from the PlayStore or AppStore. The app provides information about the connection status, for example, the signal strength, currently used wireless standard and data usage.

Practice test

We have tested the car stick several hours on the road. The installation went really smoothly. Before setup, user must know the color code, otherwise you do not initially know what that mean the color feedback. In mobile reception there is nothing to complain about. This is comparable with other sticks. You should wonder the connection speed in remote areas. Frankly speaking, the speed is just decent, but this problem can be solved by an antenna that is mounted with enough cable on the roof through the window.


Huawei E8377 Carfì is ideal for those who spend hours on the car and where several inmates want to access the Internet.  The installation and handling is simple and straightforward. However, there is currently no better alternative for the car. If you want to have wireless network around in camp or have activities in a car, Huawei E8377 would be a perfect partner.


Speedbox LTE mini II (Huawei E5786) Review

The Telekom Speedbox LTE mini II is the first mobile wireless router with integrated modem for LTE-Advanced category 6. Up to 300 megabits per second in the downlink and 50 Mbit/s in the uplink are possible in the network of Germany Telekom. The successor of the Telekom Speedbox LTE mini also has a display easy to read, a fast Wi-Fi connection and a strong battery. The unit is packed in a cardboard box, similar to those of smartphones. In addition, there is a USB power adapter (100-240V, output 5V, 2A) and a USB cable.

The modem operates in 2G, 3G and LTE in the mode. The WLAN interface supports the current 802.11ac standard on 2.4 and 5 GHz. A bright display indicates the current operating status. The 3000 mAh battery provides strong for up to 10 hours of operation. The specs of Speedbox LTE Mini II look similar to Huawei E5786 and it comes from the original factory model E5786. After customizations by Telekom, Speedbox LTE Mini II is still a powerful router.

First impression: Small and portable

The Telekom Speedbox LTE mini II is equipped with a weight of 145 grams and small pocket size like a smartphone. The front is covered by a transparent plastic sheet while the sides and back are made of matt black plastic. On the front of the display and the underlying telecom logo, we can find the power button. The display shows all sorts of information, about the network operator, the used data volume, online time or network technology. From the power and the menu button, user can do some (few) quick settings. Below is the microUSB port for charging the battery or to connect to a computer. If you remove the cover from the back, you can find the slot for the Micro SIM card and the slot for microSD memory cards.

The battery is installed in the router and unfortunately can’t be replaceable by the user. All the other ports are found under the back cover. Right next to the MiniUSB, the two ports for an external antenna is to improve the reception. The connectors are protected by narrow plastic part. In addition, Huawei has saved some much space, so it was difficult to attach the external antennas.

The modem of Speedbox mini II LTE supports LTE 800, 850, 900, 1800, 2100 and 2600 megahertz, making it work not only in Germany but also worldwide in many LTE networks overseas. The maximum speed is 300 Mbit/s in the downlink, some conditions must be met and then it can thus achieve high speeds.

Of course, the Telekom Speedbox LTE support mini II supports not only LTE but also GSM and UMTS. It works on the frequency ranges of 850, 900, 1800, and 1900 MHz on GSM and the UMTS 850, 900, 1900 and 2100MHz. So the router could use in many UMTS networks in North America. The maximum speed in the UMTS Network could reach 42.2 Mbit/s in the downlink and 5.76 Mbit/s in the uplink, if the DC-HSPA+ technology is enabled on the network.

The reception quality of the Telekom Speedbox LTE mini II is very good both in the UMTS and the LTE network, often significantly better than that of many smartphones. Even in areas with poor reception can be surfed very quickly over LTE on the Internet.


The connection to the terminal device is either via a USB port or just using wireless connection. The Telekom Speedbox LTE mini II has a current wireless 802.11a/b/g/n /ac module installed, which is fast and optionally transmits on the 2.4 GHz or 5 GHz. Up to 10 devices can be connected via WiFi through Telekom Speedbox mini II LTE and the coverage of wireless network is about 10 to 15 meters.
The operation of Telecom Speedbox LTE mini II is quite simple. After inserting the SIM card, the device must be switched on to be connected (by pressing the power button for 2-3 seconds) with a computer, tablet or smartphone via Wi-Fi. The corresponding WLAN password is displayed on the router, but can also be seen under the cover on the back. Of course, other settings such as the name and password of the wireless network can still be changed. These settings can be done directly in the browser via the web interface; alternatively there is also an app for your smartphone (Android and iOS operating system). Enter the address bar192.168.8.1 (the router’s IP) in the browser to enter the menu.

The web interface is kept very simple and allows only the most important settings. More specific things such as setting the router to a particular frequency band or a detailed diagnostic function are unfortunately missing. Also information about key reception parameters, such as RSRQ or SINR is missing entirely. There is, however, a special tool, which we will continue to introduce more below. In the tab “Statistics” can be accessed information about data usage and time spent online. It is also possible to store a data plan, such as the volume values from your own mobile calling. Below you will find three selected sample screenshots of the user interface.

Conclusion: Very good mobile LTE Router


The Telekom Speedbox LTE mini II is a very good mobile LTE router. In particular, the good speeds of up to 300 Mbit/s and the excellent reception characteristics are convincing. And the WLAN module is fast and future proof.

Huawei E5770 Mobile WiFi Router with RJ45

Huawei has unveiled a new mobile LTE hotspot E5770 with integrated RJ45 LAN interface at MWC in Barcelona. The E5770 LTE router also has a very powerful battery (5,200 mAh), achieving an operating time of up to 20 hours. The Internet could be connected via the LTE cellular modem or via LAN interface.

First MiFi hotspot with LTE Cat4 and RJ45 interface
The Huawei E5770 is the first mobile wireless router from Huawei, which is combined LTE Category 4 with a RJ45 LAN interface and a powerful battery. As we know before, the fastest 3G mobile Wi-Fi hotspot was Huawei E5730, which also has an Ethernet port, but unfortunately it did not support LTE, and a maximum of 42.2 Mbit/s could be achieved on UMTS network. Huawei E5770 provide better solution with higher speed for LTE network.
The Huawei E5770 comes with a black, leather-like plastic surface and has a small 0.96 inch OLED display on the front that displays the information such as the network operator name and the used data volume. Under a cover on the side, you will find the RJ45 LAN port and the microUSB port for charging the battery. In addition, a USB with output of 5V/2A is available, so you can use the Huawei E5770 also for charging other devices such as smartphones (“Power Bank” function).

LTE and Wi-Fi
Based on the LTE Modem in Huawei E5770, it can reach speeds of up to 150 Mbit/s for the downlink and 50 Mbit/s for the uplink in the LTE network. In the UMTS network, possible speed could reach up to 42.2 Mbit/s in the downlink on DC-HSPA+. Which frequency bands are supported, Huawei didn’t indicate at MWC in Barcelona. However, it is assumed that there will be several variants for different markets like other Huawei models such as E5786.

However, it’s a pity that Huawei E5770 wireless module only works in the 2.4 GHz band, the 5 GHz band is not available in this device. Up to 10 users can be connected simultaneously with the Huawei E5770, an eleventh device can connect to the internet via the USB interface.

Huawei E5770 is a perfect pocket router for travel. It provides a wonderful solution for business journey. When user need internet at hotel or outdoor, Huawei E5770 would be a good partner. We believe Huawei E5770 will be available soon.
