Using portable routers of the series ZTE MF90 from the operator Beeline Often limited to distributing a Wi-Fi signal to mobile devices, many users are unaware that this compact gadget can provide a more stable and secure connection to a desktop computer or laptop via a wired connection. A direct USB connection not only transfers data at high speeds, avoiding signal loss, but also simultaneously charges the device, which is critical for extended use.
The main difficulty owners of this model face is correctly switching the device's operating modes. By default, the router may only offer charging or memory card mode, ignoring the internet traffic transfer function. To activate modem mode, you need to perform a series of sequential actions in the administrator interface, which is accessed using standard methods through a browser.
In this article, we'll cover the entire setup process in detail, from the physical connection to installing the specific drivers required by the operating system to correctly recognize the network adapter. You'll learn how to avoid common mistakes and achieve the highest possible data transfer speed between ZTE MF90 and your PC.
Equipment preparation and compatibility testing
Before you begin setup, make sure you have all the necessary components on hand. This begins with the router itself. Beeline ZTE MF90, which must be fully charged or connected to a power source. To connect to a computer, you'll need a high-quality USB cable, preferably an original or certified replacement that supports data transfer, not just charging.
Please pay attention to the ports on your computer. For best performance, it is recommended to use ports USB 3.0, which typically have a blue plastic insert inside the connector. Using older USB 2.0 ports is also possible, but the bandwidth will be limited by the standard's specifications, which can become a bottleneck at high mobile internet speeds.
⚠️ Note: Cables included with cheap power banks or headphones often only have two wires for power and do not support data transfer. If your computer makes a connection sound but does not see the device as a network adapter, replace the cable.Check the SIM card status inside the router. Make sure it's installed correctly, the contact pads are clean, and there are funds in the account or an active data plan with internet enabled. The indicators on the device's body will help you quickly determine the network signal: a blinking blue or green light usually indicates successful registration with the 4G/LTE network.

Installing drivers and operating modes
After switching the mode in the web interface, the computer's operating system should detect the new network device. In an ideal scenario, Windows will automatically find and install the necessary drivers through the Windows Update service. However, for this model ZTE MF90 Manual installation or activation of a specific compatibility mode is often required, especially in older OS versions.
If automatic installation doesn't occur, open Device Manager. Find the "Network Adapters" or "Other Devices" section in the list of devices. If you see a device with a yellow exclamation mark or the name "ZTE Mobile Broadband," right-click it and select "Update Driver." Select "Browse for drivers on this computer" and specify the path to the folder if you downloaded them from the official website, or let the system search for them online.
There is an important nuance associated with the driver CDC (Communication Device Class). Some firmware versions require the "CDC Enabled" or similar option to be enabled in the web interface. Without CDC mode enabled, the computer will see the router only as a charger or storage device, ignoring network functions.
☑️ Checking driver installation
Completed: 0 / 4In rare cases, you may need to manually change the hardware ID or use a utility ZTE Driver Installer, which can be found on the official support portal or on the 4PDA forum. Be careful when downloading drivers from third-party resources, preferring trusted sources.
⚠️ Important: If after installing the drivers your internet speed remains low or your connection keeps dropping, try removing the device from Device Manager, disconnecting the cable, restarting your computer, and then reconnecting the router. This will force the system to reinitialize the connection.Setting up a network in the Windows operating system
Once the drivers are installed, a new network connection will appear in the Windows Control Panel. It will appear identical to an Ethernet (cable) connection, but the network traffic will actually flow through the USB port. The system will assign it a name like "ZTE USB Ethernet" or "Remote NDIS-based Internet Sharing Device."
By default, Windows may treat this connection as a public network, which includes stricter firewall rules. If you plan to use the router at home, it is recommended to change the network profile to "Private." To do this, go to
Settings → Network & Internet → Status, click the active connection properties, and select the desired profile. This will allow your computer to see other devices on the network, such as network printers or NAS storage.It's also worth checking your DNS settings. Sometimes your ISP automatically provides addresses that are slow. You can manually enter reliable DNS servers, such as those from Google (
8.8.8.8) or Yandex (77.88.8.8). To do this, find the protocol in the properties of the network adapter Internet Protocol version 4 (TCP/IPv4), select "Use the following DNS server addresses" and enter the values.How to reset network settings in Windows?
If the internet still doesn't work after all these steps, open a command prompt as administrator and enter the command: netsh winsock reset. After running the command, be sure to restart your computer. This will clear the network settings cache and reset the TCP/IP stack.
Check your connection status. A monitor icon with a cable should appear in the system tray (near the clock). Hovering over it will show the "Connected" status and the speed, such as "100 Mbps" or "1 Gbps," depending on the capabilities of the USB port and the router itself.

Solving common connection problems and errors
Despite the simplicity of the procedure, users may encounter a number of technical difficulties. One of the most common issues is that the computer detects the device but displays "No internet access." In this case, first check the SIM card balance and data allowance. If the data plan has been exhausted, the router may redirect requests to a payment page, which doesn't open automatically when connected via USB.
Another common error is the device constantly switching between "Charging Only" and "Modem" modes. This could indicate a faulty USB port on your computer or insufficient power. Try connecting the router directly to the motherboard (at the back of the system unit), bypassing USB hubs and extension cables, which often cannot provide the required current.
If the driver installation fails with error code 10 or 43 in Device Manager, try uninstalling the device software completely and then removing the router. Afterwards, access the router's web interface via Wi-Fi (if available) and perform a factory reset. Then, repeat the USB mode setup procedure again.
In some cases, antivirus software or a firewall may block a new network connection. Try temporarily disabling your protection and checking if the internet connection is restored. If the issue is resolved, add the router's network to your antivirus's exceptions.
⚠️ Note: The web control panel interface and menu item names may vary depending on the firmware version installed by your Beeline operator. If you cannot find the item described, search for similar names or contact your operator's technical support for the latest instructions for your specific model.Speed Comparison: USB vs. Wi-Fi
Many users wonder if there's any point in messing around with wires when Wi-Fi is available. Let's explore the advantages of a wired USB connection for this model. ZTE MF90First, it's stability. Wi-Fi signals are susceptible to interference from neighboring routers, microwave ovens, and even mirrors. A USB connection eliminates these issues, ensuring a consistent ping, which is critical for online gaming and video calls.
Secondly, energy efficiency. When using Wi-Fi, the router consumes more power to transmit the signal, which drains its battery faster. In USB mode, some power is drawn directly from the computer port, extending the device's battery life. Furthermore, the device's casing doesn't heat up, which is typical with active radio transmission.
Below is a table comparing connection characteristics for clarity:
Parameter Connection via USB Connecting via Wi-Fi Ping stability High (minimal fluctuations) Average (depending on interference) Transfer speed Up to 40-50 Mbps (limited by USB 2.0) Up to 100+ Mbps (theoretical) Router power consumption Low (PC power) High (battery operation) Security High (physical access) Requires WPA2 password protection Although theoretical Wi-Fi speeds may be higher, in practice, in urban areas with many neighboring networks, a USB modem often delivers more predictable and consistent results. This is especially noticeable when downloading large files or streaming high-definition video.
Frequently Asked Questions (FAQ)
Can ZTE MF90 be used as a regular network card all the time?
Yes, after installing the drivers and configuring USB modem mode, the operating system treats the router as a standard Ethernet adapter. You can use it just like a regular wired connection, using all Windows networking features, including port forwarding and local area networks.
Why doesn't the computer see the router even though the indicators are on?
Most likely, the device is in "Charge Only" mode. Connect to the router via Wi-Fi, go to the web interface, and switch the USB mode to "Modem" or "RNDIS." Also, check the integrity of the USB cable by replacing it with a known-good one.
Do I need to install special programs from Beeline?
Modem mode typically requires no special software (such as Highway or similar) and may even conflict with Windows system drivers. Standard RNDIS or CDC drivers, which are installed automatically or retrieved from the router's internal memory, are sufficient.
Does this method work on macOS and Linux?
Yes, the operating principle is similar. In macOS, drivers are often built into the system. In Linux, you may need to switch the mode using a utility.
usb_modeswitch, if the system by default sees the device only as a storage device. The commands depend on the distribution.Will my internet speed decrease when connected via USB?
Speed is limited by the USB 2.0 port (theoretically, the maximum is approximately 480 Mbps; in practice, modems reach 40-60 Mbps). If your Beeline plan offers speeds higher than 60 Mbps, you may not get the full speed available over 4G/5G Wi-Fi via USB.
