Once the mode is activated, a new network adapter will appear in the PC's device manager, often identified as RNDIS or Remote NDISWindows will attempt to automatically find and install the necessary drivers. If the connection doesn't occur immediately, you may need to manually update the driver through Device Manager, selecting the standard Microsoft driver.
Connecting via an external USB Wi-Fi adapter
If using your smartphone isn't feasible due to low battery or unstable connection, the most reliable solution is to purchase an external USB adapter. These compact devices, often called "whistles," plug into a USB port. USB and completely replace the built-in module. They come in a variety of form factors and price ranges.
When choosing a device, pay attention to the supported communication standards. For comfortable work in modern networks, it is advisable to choose models with support 802.11ac (Wi-Fi 5) or newer. Cheap adapters with the 802.11n standard can limit connection speeds, especially if your router supports higher speeds.
- 📶 Compact models without antenna are suitable for laptops and temporary use.
- 📡 Devices with an external antenna provide better signal reception in rooms with thick walls.
- ⚡ Adapters with USB 3.0 interface guarantee higher data transfer speeds compared to USB 2.0.
Installation usually occurs automatically: after connecting the device to the USB port, the system searches for drivers in the update database. In some cases, especially for models with advanced features or specific brands like TP-Link or Asus, you may need to install proprietary software from a disk or the manufacturer's website.
☑️ Check before purchasing an adapter
Setting up a connection via Ethernet (LAN) cable
People often forget that you don't necessarily need a wireless connection directly on your PC to access the internet. If your computer is located near a router, a direct cable connection is the most stable and fastest option. EthernetThis will eliminate problems with Wi-Fi drivers and interference in the air.
Simply connect the router's LAN port and your computer's network card using a twisted-pair cable. In most cases, configuration occurs automatically via the protocol. DHCPIf the internet doesn't appear, check the indicators on the network card—they should be lit or blinking, indicating physical contact.
In rare cases, manual IP address configuration is required. To do this, open the network settings, select "Configure adapter settings," find the local area connection, and go to the protocol properties. Internet Protocol version 4 (TCP/IPv4)Here you can enter a static address if your network configuration requires it.
Comparison of connection methods: characteristics table
To help you choose the best option, we've prepared a comparison chart. It will help you weigh the pros and cons of each method based on your current circumstances and resources.
| Method | Necessary equipment | Stability | Speed |
|---|---|---|---|
| USB modem (smartphone) | Smartphone, USB cable | Average | Depends on the phone's Wi-Fi |
| External USB adapter | USB Wi-Fi whistle | High | High (depending on model) |
| Ethernet cable | Twisted pair, router | Maximum | Maximum |
| PCIe card (internal) | Expansion card, screwdriver | High | High |
As the table shows, a cable connection offers better stability but less mobility. External adapters are a happy medium for desktop PCs lacking a built-in module. The choice depends on whether you're willing to buy additional equipment or want to make do with your existing devices.
Installing and updating drivers in Windows 10
The key to establishing a connection is the correct operation of the drivers. Even if the physical device is connected, without the correct software Windows 10 will not be able to use its functionality. The system often automatically detects a basic driver, but it may not unlock the device's full potential.
If automatic installation fails, open Device Manager from the Start menu (right-click the Start button). Look for the device with a yellow exclamation mark or an unknown device under Network Adapters. Right-click it and select Update Driver Software.
devmgmt.mscThis command, entered into the Run window (Win+R), will quickly open the Device Manager. If you don't have internet access on this PC for automatic searching, you'll need to download the driver on another device (smartphone or laptop) and transfer it via USB. Be sure to download drivers from the manufacturer's official websites, such as Realtek, Intel or MediaTek.
⚠️ Note: Driver interfaces and installation methods may vary depending on the Windows 10 version and specific hardware manufacturer. Always consult the instructions on the vendor's website.
What to do if the driver is not installed?
If the standard installation doesn't help, try removing the device completely from the Device Manager (right-click -> Uninstall device), then select "Scan for hardware changes" from the action menu. This will force the system to rescan the ports and attempt to install the driver from scratch.
Diagnosing problems with network adapters
Sometimes the connection is established, the drivers are installed, but the internet still doesn't work. In these cases, it's necessary to run diagnostics. Windows 10's built-in troubleshooter can automatically find and fix common network configuration errors. It can be accessed via Settings → Update & Security → Troubleshoot.
