How to Turn a USB Modem into a Fully-Functional Wi-Fi Hotspot: 5 Working Methods

• Network Name (SSID)
• Password (recommended) WPA2-PSK)
• Channel (better to choose car or 6–11 to minimize interference)
• Save the settings and reboot the modem.

After this, the modem should start distributing Wi-Fi. Connect your smartphone, laptop, or other device to it and check the internet connection. If the internet isn't working, check:

• 🔄 Restart your modem (sometimes physically disconnecting it for 30 seconds helps).
• 📶 Make sure your SIM card is active and there is network coverage (the indicator on the modem should be lit) 4G/LTE).
• 🔒 Check if your carrier is blocking data sharing (some plans limit the use of a modem as a router).

3. Method 2: Using a smartphone as a bridge

If your modem does not support Wi-Fi, but you have Android or iPhone smartphone, you can organize distribution through it. This method works even with the oldest modems (for example, Huawei E1550 or ZTE MF190). The scheme is simple:

1. Connect the modem to your smartphone via OTG adapter (for USB Type-C or Micro-USB).
2. Turn it on on your smartphone Modem mode (on Android: Settings → Network & Internet → Access Point).
3. Set up a network name (SSID) and password.
4. Connect other devices to your smartphone's Wi-Fi.

Advantages of the method:

• ✅ Works with any modem, even without Wi-Fi support.
• ✅ You can use your smartphone battery as a power source (useful when traveling).
• ✅ Easily configure MAC address filtering or traffic restrictions.

Flaws:

• ❌ Additional consumption of smartphone battery.
• ❌ Delays (ping) are possible due to double routing (modem → smartphone → devices).
• ❌ Some operators block data sharing from a phone (for example, tariffs marked "for smartphones only").

4. Method 3: Advanced Methods for Experienced Users

If the standard methods don't work, you can try alternative firmware or AT commandsThis is suitable for chip-based modems. Qualcomm or HiSilicon (most devices Huawei And ZTE).

4.1 Unlocking hidden functions via AT commands

Some modems (eg. Huawei E3372) have a hidden Wi-Fi mode, which is activated by the command:

AT^WWMODE=2

To send it:

1. Connect the modem to the computer.
2. Install a program to work with COM ports, for example, Putty or Terminal (Linux/macOS).
3. Find the modem's COM port number in Device Manager (Windows) or via command ls /dev/ttyUSB* (Linux).
4. Connect to the port at speed 115200 and send the command.
5. Restart your modem and a new mode should appear.

Other useful AT commands:

• AT^SYSCFG? — show the current operating mode.
• AT^RESET — reboot the modem.
• AT^NVWREX=8268,0,12,1,0,0,0,2,0,0,0,A,0,0,0 - Unlock Wi-Fi on some models Huawei.

⚠️ Attention: Incorrect use of AT commands can permanently block the modem, making it unusable. If you're unsure, consult a specialist or try other methods.

4.2. Flashing alternative software

For modems Huawei (For example, E3372h, E5372) There are custom firmware versions that add Wi-Fi functionality. Popular options:

• 📱 Hilink — official firmware with a web interface and Wi-Fi support.
• 🛠️ Stick — alternative firmware with advanced settings.
• 🔧 OpenWRT — for advanced users (requires soldering and knowledge of Linux).

Firmware instructions:

1. Download the firmware from a trusted source (for example, a forum) 4pda.ru or dd-wrt.com).
2. Connect the modem to the computer.
3. Run the firmware utility (for example, Huawei Firmware Update Tool).
4. Select the firmware file and wait for it to complete (do not turn off the modem!).
5. After rebooting, the modem should be detected as an access point.

5. Method 4: Sharing Wi-Fi via a computer (Windows/macOS/Linux)

If your modem does not support Wi-Fi, but you have a laptop or PC with a Wi-Fi adapter, you can organize distribution through it. This is called "Software AP" (software access point).

For Windows 10/11:

1. Connect the modem to the computer and wait until the Internet appears.
2. Open Command prompt (administrator) and run:

   netsh wlan set hostednetwork mode=allow ssid=MyWiFi key=12345678

   (replace MyWiFi And 12345678 to your network name and password).

3. Start the network:

   netsh wlan start hostednetwork

4. Open Control Panel → Network Connections, find the modem connection, right-click → Properties → Access and allow network usage for Local Area Connection* X (where X is your virtual network number).

For macOS:

1. Connect the modem and check the Internet.
2. Open System Preferences → Sharing.
3. Select Shared Internet: [your modem] → For computers using: Wi-Fi.
4. Click Wi-Fi settings and set the network name/password.
5. Activate sharing.

For Linux (Ubuntu/Debian):

Install create_ap:

sudo apt install create_ap
sudo create_ap wlan0 eth0 MyWiFi 12345678

(Where wlan0 - your Wi-Fi adapter, eth0 — connecting a modem).

⚠️ Attention: On some laptops, the Wi-Fi adapter may not support access point mode. Check this with the command iw list | grep "AP" (Linux) or via device Manager (Windows) If the adapter specifications do not mention SoftAP or Hosted Network, the distribution will not work.

6. Method 5: Using an external router with a USB port

If you have router with USB port (For example, TP-Link TL-MR3420, Asus RT-N12+ or Keenetic), you can connect a modem to it and distribute Wi-Fi through a router. This is the most stable solution, as the router has a better antenna and supports more connections.

Instructions:

1. Connect the modem to the USB port of the router.
2. Go to the router's web interface (usually 192.168.1.1).
3. Find the section USB modem, 3G/4G or Internet.
4. Select connection type USB modem and specify the parameters:
   • APN (eg internet.mts.ru for MTS, internet.beeline.ru for Beeline).
   • Username/Password (usually not required, but some operators require it) mts/mts or beeline/beeline).
