When wired internet is unavailable or mobile service is poor, a USB modem can be a lifesaver. However, you often need to connect not only a computer but also a smartphone, tablet, or Smart TV, which lack a USB port for direct connection. The solution is to create an access point that broadcasts the signal wirelessly.
There are several proven methods for accomplishing this, depending on your hardware and operating system. You can use Windows native features, configure a router with 3G/4G support, or use third-party software. Selecting a method Directly impacts connection stability and data transfer speed. In this article, we'll examine each option in detail so you can choose the best one for you.
Before setting up, make sure your modem is working properly in direct connection mode and has sufficient funds. It's also worth checking whether your SIM card supports tethering, as some carriers block or charge separate charges for tethering. Modern tariffs often include the "Unlimited Internet" option, but technically limit the speed when sharing data with other devices. Understanding these nuances will help you avoid unexpected expenses.
Using built-in Windows tools to create a hotspot
The simplest and most accessible method, which doesn't require installing additional software, is available to owners of computers running Windows 10 and Windows 11. The operating system has a built-in "Mobile Hotspot" feature that turns a laptop or PC with a Wi-Fi module into a fully-fledged router. To activate this feature, the wireless adapter drivers must be updated to the latest version.
Go to the Start menu and select "Settings," then open "Network & Internet." In the left column, find "Mobile hotspot." Here, you need to select your internet connection source from the drop-down list—in our case, it would be Ethernet or the name of your USB modem (for example, Remote NDIS based Internet Sharing Device). Next, turn on the switch "Allow other devices to use my internet connection."
It's important to configure security settings correctly to prevent unauthorized access to your network. Click the "Edit" button and enter the network name (SSID) and password. WPA2-Personal encryption is recommended, as it provides an adequate level of data protection. After saving the settings, the system will automatically launch the access point.
- 📶 Make sure your computer's Wi-Fi adapter is turned on and not in airplane mode.
- 🔒 The password must be at least 8 characters long to comply with WPA2 security standards.
- ⚡ If you have a connection but the internet isn't working, check the DNS settings in your modem adapter properties.
It's important to note that this method requires the computer to be constantly on, which increases power consumption. Furthermore, the Wi-Fi connection speed will be limited by the bandwidth of your laptop's wireless adapter, which only operates in one frequency band.
Setting up distribution via the command line in Windows
For users who prefer finer control over network settings, or in cases where the graphical interface doesn't work, the command line method is ideal. This method often saves the day when the built-in hotspot fails to start for some reason or is unstable. It requires careful command entry, but produces more predictable results.
Launch the command prompt as administrator. To do this, search for cmd, right-click, and select the appropriate option. The first step is to check for virtualization support. Enter the command netsh wlan show drivers and find the line "Hosted network support." If it says "Yes," you can continue.
Next, you need to create a network configuration. Enter the command: netsh wlan set hostednetwork mode=allow ssid=MyNetworkName key=MyPassword123Replace MyNetworkName with your desired network name and MyPassword123 with a strong password. After creating the network, you need to start it with the command netsh wlan start hostednetworkA new virtual adapter will now appear in Network Connections.
⚠️ Attention: If after running the command the network status is "Not running", try updating the Wi-Fi adapter driver or temporarily disabling the antivirus software, which may be blocking the creation of the virtual network.
The final step is to enable internet access. Open "Network Connections" (you can do this via the command ncpa.cpl), find your USB modem connection, open its properties, and go to the "Access" tab. Check "Allow other network users to connect through your Internet connection" and select the virtual network you created from the list.

Using specialized software: Connectify and similar
If standard Windows tools seem too complicated or error-prone, specialized programs can help. One of the most popular solutions is Connectify HotspotThis software handles all the technical setup, providing a user-friendly interface with a variety of additional features, such as ad blocking and traffic monitoring for connected clients.
The main advantage of such programs is their ability to work even with outdated Wi-Fi adapter drivers, which may not support standard Windows features. The program automatically selects optimal encryption and frequency settings. However, it's worth remembering that most such applications are paid or have limitations in the free version, such as battery life or speed.
An alternative could be programs from modem manufacturers, such as MTS Connect or BeOnline, which sometimes have a built-in seeding function, although it is implemented rather primitively. There are also lightweight utilities like MyPublicWiFi, which do not require installation and work immediately after launch.
| Program | License type | Key feature | Complexity |
|---|---|---|---|
| Connectify Hotspot | Paid / Free Trial | Ad blocking, firewall | Low |
| MyPublicWiFi | Free | Logging visited URLs | Average |
| Virtual Router Plus | Free (Open Source) | Minimalism, no advertising | Low |
| OSToto Hotspot | Free | Simple interface, autostart | Low |
Why might programs not see the modem?
Some Wi-Fi sharing programs require the modem to be detected by the system as a network adapter, not a COM port. If your modem only shows up as a port, try switching its operating mode using AT commands or installing the drivers in "Network Adapter" mode.
Setting up a network via a router with 3G/4G support
The most stable and energy-efficient solution is to use a full-fledged router with a USB modem. This router takes on all the work of maintaining a connection to the cell tower and distributing the signal, freeing up your computer's resources. You don't need to keep your PC running 24/7; the router itself is sufficient.
When choosing equipment, pay attention to the modem compatibility list on the router manufacturer's website. Not all TP-Link, Asus or MikroTik Compatible with any device. Reflashing the device or installing alternative firmware is often required, for example, OpenWrt or DD-WRTto achieve full compatibility with LTE modems.
Configuration is usually done through the router's web interface. In the WAN or Internet Connection Type section, select "3G/4G" or "USB Modem." Next, enter your carrier's APN settings (e.g., internet (For many operators), the dial-up number, and authorization information. After saving the settings, the router will reboot and attempt to establish a connection.
- 📡 Use a USB cable with ferrite beads to minimize interference.
- 🔌 Connect the modem via a USB hub with external power if the router does not provide sufficient current.
- ⚙️ Huawei modems often require a command
AT^CURC=1to stabilize the connection.
⚠️ Attention: When using routers with a USB port, make sure that the router's power supply has sufficient power (usually at least 1A per USB port), otherwise the modem may constantly turn off during load surges.
Creating a hotspot on an Android smartphone
If you don't have a computer or router handy, but have an Android smartphone with OTG (On-The-Go) support, you can share internet from a USB modem through it. This turns your phone into a powerful mobile router. This will require an app that supports external modems, as the standard Android functionality often doesn't recognize USB dongles.
One of the popular solutions is the application PPP Widget 3 or specialized versions of Android drivers. The process begins by connecting the modem to the phone via an OTG cable. The system should detect the device. If automatic connection is not achieved, you will need to manually enter the APN settings in the app.
Once the modem is successfully connected to the internet, enable the "Wi-Fi Hotspot" or "Tethering and Hotspot" feature in your phone's settings. Your smartphone will now take internet from the USB modem and broadcast it over Wi-Fi. This solution is great for traveling, but it can quickly drain your phone's battery.
Be mindful of your device's temperature. When actively transferring data, the phone's processor and communication module can become very hot. It's recommended to remove the protective case and place the device on a hard surface to improve heat dissipation. Also, check whether your data plan limits your tethering data usage.
Compatibility issues and solutions
During setup, users often encounter the problem that the computer sees the modem but can't use it for network sharing. One common issue is the modem's operating mode. Some devices are detected by default as a CD-ROM drive with drivers, rather than as a network card. Switching to modem mode (HiLink or Stick mode) may require installing drivers or using a utility. Mode Switch.
Another important aspect is IP addressing. Sometimes the modem's addressing conflicts with the addressing of the Wi-Fi network being created. For example, if the modem uses a subnet 192.168.1.x If the virtual adapter is also configured for this subnet, a conflict will occur. In this case, you must manually change the virtual adapter's IP address in the IPv4 protocol properties.
DNS issues are also possible. If websites don't open, but instant messaging apps work, try setting up static DNS servers (for example, Google's: 8.8.8.8 And 8.8.4.4) in the settings of the network connection you're sharing. This often resolves the "No internet access" issue for connected clients.
⚠️ Please note: Modem and carrier settings interfaces may vary. If you can't find a specific setting, check the technical documentation on your equipment manufacturer's official website or in your carrier's personal account.
Frequently Asked Questions (FAQ)
Why is my Wi-Fi speed significantly lower than the speed directly from the modem?
Speed may drop due to double signal conversion, limitations of the computer's Wi-Fi adapter (especially if it only operates in the 2.4 GHz band), or limitations of the PC's processor when encrypting traffic. Distance and the presence of obstacles between the device and the transmitting computer also play a role.
Is it possible to share the Internet if the modem is locked to a specific operator?
Yes, you can. SIM card locking only affects which carrier the modem accepts. It doesn't affect the ability to share data from an already connected modem. However, if the modem is locked, you'll need to use the SIM card from the carrier it's designed for.
Does the operator charge an additional fee for internet distribution?
This depends on the terms of your data plan. Many modern plans "for smartphones" or "for tablets" have a technical limit on data sharing (TTL) or charge an additional fee for it. Plans "for modems" (USB) usually allow data sharing but have traffic limits. Check the terms in your contract.
How to increase the range of a created Wi-Fi network?
Standard methods of increasing a laptop's transmit power are impossible without the risk of frying the module. The best way is to connect an external USB Wi-Fi adapter with an antenna to the computer. You can also use a router in client mode (WISP), which will receive the signal from the laptop and amplify it.
Does distribution work if the computer goes into sleep mode?
By default, when the computer goes to sleep, the Wi-Fi adapter is disabled, and sharing stops. To prevent this, disable USB ports and the Wi-Fi adapter in Windows power settings and set the power plan to "High Performance."
