The situation when Wi-Fi on your computer When something suddenly stops working, it always catches you off guard. You're used to instant internet access, and a sudden loss of connection can disrupt your workflow or deprive you of entertainment. In the operating system Windows 10 Wireless network problems can arise for a variety of reasons, from a simple router failure to driver conflicts or system errors.
Before panicking or taking your laptop to a service center, it's worth running a basic diagnostic. Often, a simple reboot or flipping a switch on the device's case can solve the problem. However, if standard methods don't help, it's necessary to delve deeper into the operating system settings and understand the root cause. adapter refuses to see available networks.
In this article, we'll walk you through a step-by-step process to help restore your connection. We'll cover both software fixes and hardware testing, so you can troubleshoot the issue yourself and restore your stable internet connection.
Primary diagnostics and equipment testing
The first step is to rule out physical causes for the lack of signal. If you have a laptop, make sure airplane mode isn't accidentally activated. Check your keyboard for a button with an image of an antenna or airplane; it's often combined with the [unclear] key. FnPressing this combination can completely disable the communication module, and the system will claim that there are no networks at all.
You should also pay attention to the router's indicator lights. If the light WLAN If the wireless network icon on your router isn't lit or is blinking abnormally, the problem may be with your ISP or the router itself. Try rebooting the router by unplugging it for 10-15 seconds. This clears any temporary errors in the device's memory.
⚠️ Important: If the Wi-Fi indicator on your router is on, but your computer can't see any networks, try connecting to another device (smartphone or tablet). This will help you determine whether the problem is with your computer or the access point.
In some cases, reinstalling the SIM card in USB modems or checking the antenna connections if you're using a desktop PC with an external module can help. Make sure the antenna is securely screwed into the connector on the back of the system unit.
Using the built-in troubleshooter
operating system Windows 10 Equipped with a powerful built-in automatic diagnostic tool. It doesn't always work miracles, but in 60% of cases it can independently find and fix configuration errors. TCP/IP protocol or reset the adapter settings.
To launch the utility, right-click the network icon in the system tray (near the clock) and select "Troubleshoot." The system will begin a scan, which may take several minutes. While the scan is running, you may see a message indicating that network adapter does not have a valid configuration.
If the system prompts you to apply a fix, accept it. This often involves restarting the wireless network management service. After the process is complete, your computer may require a reboot, after which the connection should be restored.
☑️ Basic network check
Updating and reinstalling Wi-Fi adapter drivers
The most common reason why Wi-Fi won't connect, is incorrect driver operation. This is the software that allows the operating system to communicate with the hardware. After major Windows updates, old drivers may conflict with the new version of the system.
To check the status of your drivers, open device ManagerTo do this, right-click the Start button and select the appropriate option from the menu. Find the "Network Adapters" section and expand it. If you see a device with a yellow exclamation mark or an unknown device, the problem is with the driver.
Right-click on your Wi-Fi adapter (the name often contains the words Wireless, 802.11, Wi-Fi or brands Intel, Realtek, Qualcomm) and select "Uninstall device." Don't worry, the system won't physically remove the adapter. After uninstalling, click "Action" → "Scan for hardware changes" in the menu, and Windows will attempt to install the driver again.
What to do if the driver is not found automatically?
If Windows cannot find the driver itself, you will need to download it from the official website of the laptop or motherboard manufacturer on another device and install it manually via the .exe or .inf file.>
⚠️ Warning: Before uninstalling the driver, make sure you have access to its installer on a flash drive or other device, especially if you do not have a wired Ethernet connection.
Reset network settings in Windows 10
If driver manipulation doesn't help, you should perform a full network reset. This function returns all network settings to factory defaults, deleting saved Wi-Fi profiles, static IP addresses, and VPN settings.
Go to the "Settings" menu (the gear icon in the Start menu), then select "Network & Internet." At the very bottom of the "Status" page, you'll find a link called "Network reset." Click it, then click "Reset now." Your computer will warn you that it will restart in 5 minutes.
After rebooting, you'll have to re-enter your wireless network password, as all saved security keys will be deleted. However, this often helps when configuration errors have accumulated in the registry, blocking the connection.
Checking WLAN service and power settings
A special system service is responsible for wireless networking in Windows. If it's stopped or malfunctioning, Wi-Fi won't connect. Click Win + R, enter the command services.msc and press Enter.
In the list that opens, find the service WLAN AutoConfigMake sure its startup type is set to Automatic and its status is Running. If the service is stopped, click the Start button.
The problem could also be related to your power settings. Windows 10 is a power-saving device and may disable your Wi-Fi adapter to reduce battery drain. Find your adapter in Device Manager, go to "Properties" → "Power Management" tab, and uncheck "Allow the computer to turn off this device to save power."
| Parameter | Normal value | Problematic meaning |
|---|---|---|
| WLAN AutoConfig Service | In progress | Stopped |
| Service startup type | Automatically | Manual / Disabled |
| Power saving mode | Disabled | Disconnection allowed |
| Driver status | The device is working properly. | Error code (10, 43, 28) |
Resetting the TCP/IP stack via the command line
For advanced users who are unable to connect to Wi-Fi due to network conflicts, resetting the protocol stack via the command line is a suitable option. This method is effective when the system detects networks but cannot obtain an IP address from the router.
Launch Command Prompt as administrator. Enter the following commands one by one, pressing Enter after each:
netsh winsock resetnetsh int ip reset
ipconfig release
ipconfig renew
ipconfig flushdns
After running all commands, be sure to restart your computer. These actions flush the DNS cache, reset the Windows socket settings, and refresh the IP configuration, which often resolves hidden connection errors.
⚠️ Note: Command line interfaces and available commands may vary slightly depending on the Windows 10 build version. If a command causes an error, try skipping it and running the next one.
Frequently Asked Questions (FAQ)
Why does Wi-Fi work on my phone but not on my computer?
This indicates a problem with the computer's settings or hardware. Most likely, the DNS settings are incorrect, the Wi-Fi module driver is outdated, or the router has a static IP address that conflicts with the router's current network.
What does "Can't connect to this network" mean?
This error often occurs when the password is entered incorrectly, the encryption type mismatches (for example, WPA2 vs. WPA3), or when the computer tries to connect to a network with saved but now incorrect security settings.
How to check if the Wi-Fi module is enabled in BIOS?
When booting your computer, press F2 or Del. In the BIOS, find the Advanced or Configuration section. Look for the Wireless, WLAN Device, or Onboard Wi-Fi option and make sure it's set to Enabled.
Can antivirus block Wi-Fi?
Yes, some security features in third-party antiviruses (such as network control or firewall) may block the connection. Try temporarily disabling your antivirus to check.
