Network adapters.Look for devices with names like Wireless, Wi-Fi, 802.11 or Dual BandIf there are none, your PC is not equipped with a wireless module.
Typical adapter names in the manager:
- 📡 Intel(R) Wi-Fi 6 AX200 (modern motherboards)
- 📡 Qualcomm Atheros AR9485WB-EG (mid-range laptops)
- 📡 Realtek RTL8821CE (budget solutions)
- 📡 Broadcom 802.11ac (obsolete models)
If you don't have an adapter, go to section on USB modulesIf there is, but it doesn't work, read about it. updating drivers.
2. Standard Wi-Fi connection in Windows 10/11

A common cause of connection issues is outdated or missing drivers. Here's how to update them:
Method 1: Via Device Manager
Open device Manager (
devmgmt.msc).Find your Wi-Fi adapter in the section
Network adapters, right-click →Update driver.Select
Automatic searchand wait for it to complete.
Method 2: Manually from the manufacturer's website
If automatic search does not help:
Find out the exact model of the adapter (in the device manager).
Download the driver from the official website:
- 🖥️ For Intel: support.intel.ru
- 🖥️ For Realtek: realtek.com
- 🖥️ For Qualcomm Atheros: qualcomm.com
Install the driver and restart your PC.
If after updating the drivers the Wi-Fi device disappears from the list of devices, roll back to the previous version of the driver (in the Device Manager → Properties → Roll back).
4. Connecting via USB Wi-Fi adapter
If your PC doesn't have a built-in module, the easiest way is to buy one. USB Wi-Fi adapterThese devices start at 500 rubles and connect in seconds. Here's what you need to know when choosing:
| Characteristic | Recommendation | Example of a model |
|---|---|---|
| Wi-Fi standard | Not lower 802.11ac (Wi-Fi 5) |
TP-Link Archer T2U Nano |
| Frequencies | Dual-band (2.4 GHz + 5 GHz) |
ASUS USB-AC56 |
| Speed | From 300 Mbps (for Full HD streaming) |
Tenda U3 |
| Antenna | External for weak signal | D-Link DWA-171 |
How to connect:
Insert the adapter into the USB port (preferably
USB 3.0for high speed).Wait for the drivers to install automatically (if they are not installed, download them from the manufacturer's website).
Connect to the network via the Wi-Fi icon in the tray (see Section 2).

⚠️ Attention: Cheap adapters without an external antenna (150 Mbps) may not cope with modern routersWi-Fi 6Before purchasing, check if your router supports outdated standards (802.11n).
5. Alternative connection methods without a Wi-Fi adapter
If you don't want to buy a USB module, there are workarounds:
Method 1: Smartphone as a hotspot
Any modern smartphone (Android or iPhone) can distribute the Internet via Wi-Fi:
Cons: battery drains quickly, traffic limitations (if you use mobile internet).
Method 2: Powerline adapters (via electrical wiring)
Devices Powerline transmit the internet signal through electrical wires. You need:
Connect one adapter to the router via cable.
Insert the second adapter into a socket next to the PC and connect it with a cable
Ethernet.
Pros: stable connection without speed loss. Cons: expensive (from 2,000 rubles per set), depends on the quality of the wiring.
Method 3: Wi-Fi Bridge (WDS)
If you have a second router, you can set it up as follows: signal repeater:
- 📶 Connect the second router to the first one via cable.
- 📶 Activate the mode in the settings of the second router
WDSorRepeater. - 📶 Connect your PC to the second router using a cable.
6. Troubleshooting Weak Wi-Fi Signals
If the network connects but keeps dropping out or the speed is slow, try:
- 📍 Move the router closer to the PC (ideally, 1–1.5 m from the floor).
- 🔄 Change the Wi-Fi channel in the router settings (use network analyzers like Wi-Fi Analyzer for Android).
- 🛡️ Turn it off
WPSand turn it onWPA3(in the sectionWireless Security). - 📶 Install repeater (signal booster) or replace the router antennas with more powerful ones.
If the problem is only on your PC and other devices are working fine:
- 🖥️ Check your power settings:
Control Panel → Power Options → Change Plan Settings → Additional Power Settings→ find the parameterWireless Network Adapter Settingsand installMaximum performance. - 🔧 Turn it off
TCP/IP autoconfiguration:netsh int tcp set heuristics disablednetsh int tcp set global autotuninglevel=restricted
netsh int tcp set global rss=enabled(run the commands in
Command line(as administrator).
⚠️ Note: If Wi-Fi is lost after a Windows update, check if the system has disabled the adapter to save power. Go toDevice Manager → Network Adapters → Properties of your adapter → Power Managementand uncheckAllow shutdown....

|---|---|---|
| Wi-Fi mode | 802.11ac (or ax, if supported) |
Wireless → Basic Settings |
| Channel width | 20/40 MHz (for 2.4 GHz) or 80 MHz (for 5 GHz) |
Wireless → Channel |
| Beamforming | Included (improves signal for specific devices) |
Wireless → Advanced |
| MTU | 1500 (standard value) |
Network → WAN |
If you have dual-band router, connect your PC to the network 5 GHz — there's less interference and higher speed. To do this:
In the router settings, enable a separate network for
5 GHz(if disabled).On your PC, in the list of networks, select the network with the set-top box
5G(For example,MyWiFi_5G).
FAQ: Frequently asked questions about connecting Wi-Fi to a PC
My PC can't see any Wi-Fi networks, even though I have an adapter. What should I do?
Check:
