How to install a Wi-Fi adapter on a computer without a disc drive: 4 working methods

• If the file .exe - run it as administrator.
• If the folder contains files .inf And .sys - V Device Manager select "Update driver» → «Search for drivers on this computer» → specify the path to the folder.

Critical! If the adapter is not detected after installing the driver, check that you have downloaded the correct version for your system bitness (x64 or x86). You can find it in Settings → System → About (chapter "System type»).

Manufacturer	Link to drivers	Peculiarities
TP-Link	tp-link.com/support/download	Drivers are often universal for several models (for example, TL-WN725N v2/v3).
ASUS	asus.com/support/Download-Center	For adapters of the series PCe-AC additional software required ASUS AiRadar.
Intel	intel.com/content/.../download/...	Drivers for AX200/AX210 support Wi-Fi 6 and require Windows 10 20H1 or later.
Realtek	realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-usb-3-0-software	They often conflict with universal Windows drivers. Uninstall older versions before installing.

What should you do if there is no driver for your model on the website?

Sometimes manufacturers remove old drivers from their websites. In this case, try:

1. Search for a driver by device ID via DevID.info or DriverPack Solution (only download from official sources!).

2. Use a driver from a similar model (for example, for TP-Link TL-WN722N v1 And v2 the same files may be suitable).

3. Contact the manufacturer's support team, providing the device ID.

4. Installing drivers without the Internet (offline)

If your PC isn't connected to the network, you'll have to download the drivers from another device and transfer them via a flash drive. Here are the step-by-step instructions:

1. Find another PC/laptop with internet access. Download the driver for your adapter model (as described in section 3) and save it to a flash drive.
2. Connect the flash drive to the target PC. If the adapter is already inserted, proceed to installation. If not, connect it. after copying drivers (otherwise Windows may try to install them automatically and fail).
3. Install the driver manually:
   • Open device Manager → find the unknown device.
   • Right click → «Update driver» → «Search for drivers on this computer».
   • Specify the path to the folder with drivers on the flash drive.

If you don't have a second PC, but you have a smartphone, you can download the driver directly to your phone and then transfer it to your PC via OTG cable or via Bluetooth. To do this:

1. On your smartphone, go to the adapter manufacturer's website and download the driver (file .zip or .exe).
2. Connect your phone to your PC via USB cable and copy the file to any folder.
3. Unzip the archive (if necessary) and install the driver as described above.

⚠️ Attention: When transferring drivers from a smartphone, make sure the file isn't damaged. Before copying, check its size—it should match the one indicated on the manufacturer's website.

For adapters Intel (For example, AX200) can be used universal driver from Microsoft, but it may not support all features (eg. Wi-Fi 6 or Bluetooth 5.0). To avoid problems, download branded drivers even for offline installation.

5. Troubleshooting PCIe and M.2 adapters

Internal Wi-Fi modules (PCIe or M.2) often cause more problems than USB adapters. Here are the typical errors and their solutions:

• 🔴 The adapter is not detected at all:
  • Check if it is installed in the slot correctly. M.2 Wi-Fi The modules must be fixed with a screw.
  • Make sure the slot M.2 Key A/E (for Wi-Fi), not Key M (for SSD).
  • In BIOS/UEFI, enable the option Wireless LAN or WLAN (usually in the section Advanced → Onboard Devices).
• 🔴 The driver installs, but Wi-Fi doesn't work:
  • Check if the antennas are connected (for PCIe adapters). They must be tightly screwed to the connectors. IPEX.
  • Update your motherboard BIOS - older versions may not support new modules.
  • Disable the built-in Wi-Fi module (if any) in Device Manager, to avoid conflicts.
• 🔴 The adapter gets hot or switches off:
  • For PCIe adapters (for example, ASUS PCE-AC88) check if the video card is blocking it - sometimes you need to use an extension cord.
  • Install additional cooling (for example, a small fan next to the module).

For adapters Intel (For example, AX200/AX210) installation may be required additional software — Intel PROSet/Wireless SoftwareIt adds advanced settings (such as traffic prioritization or network monitoring). You can download it from Intel's official website.

⚠️ Attention: Some motherboards (especially from Gigabyte or MSI) have white list Supported Wi-Fi modules. If your adapter isn't on this list, it may not work even with the correct drivers. Check compatibility on the board manufacturer's website.

If you have replaced the built-in Wi-Fi module in your laptop (for example, in Lenovo ThinkPad or HP Pavilion), after installing a new module, you may need BIOS reset (remove the CMOS battery for 30 seconds or use a jumper CLR_CMOS on the motherboard).

6. Alternative methods: without drivers and disks

If none of the previous methods worked, try these options:

• 🔄 Use universal drivers:
  • For chip adapters Realtek (For example, RTL8188EU or RTL8812AU) a package will do Realtek Wireless LAN Driver from the official website.
  • For Mediatek (previously Ralink) download the driver from mediatek.com.
• 🖥️ Virtual machine with internet:
  • Install VirtualBox or VMware, create a virtual machine with Windows.
  • Connect the Wi-Fi adapter to the virtual machine (via USB passthrough) and download the driver inside it.
  • Transfer the driver to the main system.
• 📱 Mobile hotspot as a temporary solution:
  • Activate the hotspot on your smartphone and connect your PC via USB (mode USB-ethernet).
  • Download the driver and install it, then switch to Wi-Fi.
• 🔧 Linux Live USB:
  • Boot from the flash drive with Ubuntu or Linux Mint — many Wi-Fi adapters work in Linux out of the box.
  • Download the driver for Windows and save it to another flash drive.

For chip-based adapters Broadcom (found in MacBook or some Dell) may be required driver patchFor example, for Broadcom BCM4360 in Windows you need to install it additionally Boot Camp Drivers from Apple. These drivers can be found on relevant forums (for example, tonymacx86.com).

Important! If you use USB adapter on a chip Realtek RTL8188EU and it keeps turning off, try turning it off Device Manager parameter "Allow the computer to turn off this device to save power» (tab «Power management»).

7. Troubleshooting: The adapter is installed but not working

If the driver is installed, but Wi-Fi still doesn't connect to networks or is unstable, follow these steps:

1. Check network visibility:
   • Open Command line (Win + R → cmd → Enter).
   • Enter the command:

     netsh wlan show networks mode=bssid

     If the network list is empty, the problem is with the antenna or driver.

2. Reset the TCP/IP stack:
   • Perform in Command line (as administrator):

     netsh int ip reset
     netsh winsock reset
     ipconfig /flushdns

   • Restart your PC.
3. Check for device conflicts:
   • Open device Manager → View → Resources by Type.
   • Find conflicting devices (marked with an exclamation mark).

• If the problems started after the update, Device Manager click on the adapter → «Properties» → «Driver» → «Roll back».

If the adapter PCIe/M.2 is detected, but the Wi-Fi speed is low (for example, instead of 300 Mbps - 50 Mbps), check:

• Router settings: is the standard enabled? 802.11ac (5 GHz) or 802.11ax (Wi-Fi 6).
• Channel and bandwidth: Select the channel in your router settings. 40 MHz or 80 MHz (and not 20 MHz).
• Antenna placement: They should be spaced at least 10 cm apart.

⚠️ Attention: If the adapter still doesn't work after all these steps, test it on another PC. The problem may be with the device itself (for example, a chip burned out after a power surge). In this case, the only option is to replace the adapter or contact a service center.
