Using a cable ensures a more stable signal and lower latency (ping), which is critical for online gaming or video conferencing. Furthermore, this connection method often bypasses carrier data sharing restrictions that apply to standard Wi-Fi hotspots. Let's look at how to set up a connection on different platforms.
Advantages of a USB modem over Wi-Fi sharing
The first thing to understand is why it's worth bothering with wires when wireless technologies are available. The main advantage of a USB connection is the lack of speed loss due to radio interference. When you share the internet via Wi-Fi hotspot, the signal is subject to interference from walls, microwave ovens and neighboring routers, which reduces the actual throughput.
Additionally, a cable connection allows you to simultaneously charge your smartphone. Sharing internet via Wi-Fi generates significant heat and quickly drains the battery, which can lead to battery degradation with frequent use. In USB modem mode, the phone draws power directly from the computer, operating in a more energy-efficient mode.
- 🔒 Safety: Data is transmitted over a physical channel and cannot be intercepted remotely, as in open Wi-Fi.
- ⚡ Speed: USB 2.0 and 3.0 have significantly higher throughput than most mobile communication standards.
- 🔋 Energy efficiency: The phone does not discharge, but charges while it is in use.
It's important to note that when connected via USB, the smartphone doesn't emit radio waves, reducing the electromagnetic environment around the user. This is especially important if you work on a computer for long hours. For maximum comfort and productivity Using a USB cable is the most rational choice in a stationary workplace.

Preparation of equipment and cable
Before starting the software setup, you need to ensure the physical hardware is working properly. Not every USB cable is suitable for data transfer; many cheap cables are designed solely for charging and lack the necessary wires for data exchange. Using such a cable will only charge the phone, but the computer will not detect the new network device.
It is recommended to use the original cable that came with your smartphone, or a high-quality analog that supports the standard USB 2.0 and longer. Cable length is also important: cables that are too long (more than 1.5-2 meters) without shielding can introduce interference and reduce connection speed. It's best to connect the device directly to the motherboard port on the back of the PC, bypassing USB hubs.
Make sure your smartphone's mobile data plan is enabled. Even if you know how to share Wi-Fi via USB, data transfer is impossible without an active connection from your carrier. Check your balance and data plan.
If you are using a desktop computer, make sure that the basic drivers for the USB controller are installed. In modern operating systems, such as Windows 10 And Windows 11, this happens automatically, but on older builds or specific versions Linux Manual installation of smartphone manufacturer's drivers may be required.
Setting up a USB modem on Android
The process of activating the modem mode on devices with the operating system Android is fairly standardized, although the names of menu items may differ depending on the manufacturer's shell (for example, MIUI, OneUI, ColorOS). First, connect your smartphone to your computer using a cable and wait for the system to detect the device.
Go to your phone's settings. You'll need to find the network section. Typically, the path looks like this: Settings → Connections → Mobile hotspot & tetheringIn some versions of Android, this option is located directly in the main settings menu or in the "More" section.
Find the switch USB modem and enable it. If the option is grayed out, check the cable or try a different USB port. Once enabled, a USB icon will appear in the status bar on your smartphone, and a new network connection icon will appear in the system tray on your computer.
☑️ Checking Android settings
In some cases, especially on custom ROMs, you may need to select a USB mode. To do this, pull down the notification shade when connecting the cable, tap the "USB Charging" notification, and select the mode. File Transfer (MTP) or Modem modeThis action forces the necessary services to start to handle network traffic.
⚠️ Attention: Menu interfaces may change with operating system updates. If you don't find an exact match, look for synonyms: "Network & Internet," "Wireless Networks," "Modem Mode."
Instructions for iPhone (iOS) users
For device owners Apple lucked out with an even simpler procedure known as Personal Hotspot (Modem mode). However, there is an important nuance: for a USB modem to work on a Windows computer, iTunes or drivers must be installed. Apple Mobile Device SupportWithout them, the computer will not be able to recognize the iPhone as a network device.
On iPhone, go to Settings → Cellular → Personal Hotspot (or simply "Tethering & Personal Hotspot" in the main menu). Turn on the "Allow Others" switch. If prompted to "Turn on Wi-Fi and Bluetooth," select "USB Only" if you only want to use a cable connection, or "On" if you plan to use a combination of both.
Connect your iPhone to your computer using a Lightning or USB-C cable. You'll see a prompt on your iPhone asking "Trust this computer?" Be sure to click Trust and enter your screen unlock code. This action is necessary for data security and to allow network packets to be transmitted.
After trust is confirmed, a new adapter named "Apple Mobile Device Ethernet" or something similar should appear in the Windows network connections list. Connection speed in this case is limited by the USB port bandwidth and the cellular network signal, but stability will be high.
Installing drivers in Windows 10 and 11
Windows operating systems offer good compatibility with mobile devices, but sometimes automatic driver installation fails. If, after connecting your phone and enabling tethering, an unknown device with a yellow exclamation mark appears in Device Manager, you'll need to update the drivers manually.
Open device Manager (click Win + X and select the appropriate item. Find the "Network adapters" or "Other devices" section. If you see a device with the name of your phone or "Remote NDIS-based Internet Sharing Device" but it isn't working correctly, right-click it and select "Update driver."
Select "Search automatically for drivers." If Windows doesn't find anything, you'll have to download drivers from the official website of the smartphone manufacturer (Samsung, Xiaomi, Huawei, etc.) or use universal drivers. Google USB Driver For Android. For iPhone, as mentioned, you need iTunes.
| OS | Necessary software | Connection type | Complexity |
|---|---|---|---|
| Windows 10/11 | MTP / iTunes Drivers | USB / Bluetooth | Low |
| macOS | Not required (built-in) | USB / Wi-Fi | Minimum |
| Linux (Ubuntu) | usb-modeswitch | USB | Average |
| Chrome OS | Not required | USB | Low |
In some cases, removing the device from Device Manager and then scanning for hardware changes helps. This forces Windows to reinstall the driver, which often resolves the version conflict.
Troubleshooting and diagnostics
Even with proper setup, there may be situations where the internet doesn't work or is unstable. One common cause is speed throttling by your carrier. If you're tethering, your carrier may throttle your speed to 64 or 128 kbps unless you've purchased a special package. Check your speed using this service. Speedtest directly on the phone and via USB modem.
Another common issue is IP address conflicts. If your computer and phone are trying to use the same addresses on the local network, the connection will fail. Try resetting your computer's network settings. Open the Command Prompt as administrator and enter the following command:
netsh int ip resetAfter running the command, be sure to restart your computer. It's also worth checking whether your firewall or antivirus is blocking the new network connection. Temporarily disable your firewall and test your network access.
If your speed is low, try changing your connection point in the APN settings on your phone. Sometimes changing the protocol from IPv6 to IPv4 or vice versa can improve connection stability. Go to Settings → Mobile network → Access point names (APN) and create a new point with your operator's parameters.
⚠️ Attention: Be careful when changing APN settings. Incorrect settings can lead to complete loss of mobile internet service. Write down or photograph the original settings before editing.
Frequently Asked Questions (FAQ)
Is it possible to share WiFi via USB if there is no SIM card on the phone?
No, the phone itself must have an active connection to the carrier's network to share the internet. However, if the phone is connected to a Wi-Fi network, some Android models allow you to use the "Wi-Fi repeater" feature via USB, transmitting the Wi-Fi internet to a PC, but this depends on the specific model and OS version.
Why does the computer see the phone as a charger, but not as a modem?
You're most likely using a "charging-only" cable that doesn't have data lines. The issue could also be with the USB port or missing drivers. Try a different cable and port.
Does USB modem reduce internet speed compared to Wi-Fi?
In contrast, a USB connection typically provides more stable and sometimes higher speeds, as it eliminates signal loss. The only limitations are the mobile internet speed and the USB port's bandwidth.
Do operators charge extra for a USB modem?
