4. Update or reinstall Wi-Fi drivers

Outdated or corrupted drivers are one of the most common causes of Wi-Fi problems. Even if Device Manager If there's no exclamation mark, this doesn't guarantee the driver is working correctly. Here's how to update it manually:

Method 1: Automatic update via Windows

1. Open "Device Manager" (Win + X).
2. Find your Wi-Fi adapter, right-click on it and select Update Driver → Automatic search.
3. Wait for the process to complete and restart your laptop.

Method 2: Installing the driver from the manufacturer's website

If the automatic update doesn't help, download the driver from the official website:

1. Determine the model of your adapter (see section 2) and the model of your laptop.
2. Go to the laptop manufacturer's website (ASUS, Lenovo etc.) or adapter (Intel, Qualcomm, Realtek).
3. In the section "Support" or Drivers Find the latest driver for your model and Windows.
4. Install the driver and restart the laptop.

Attention! If after updating the driver Wi-Fi stops working completely, roll back to the previous version via "Device Manager" (right click on the adapter → "Properties" → tab "Driver" → Rollback).

5. Checking router settings

If Wi-Fi works on other devices but not on your laptop, the problem may lie in your router settings. Here's what to check:

• 🔒 Network security type. Make sure your router is using WPA2-PSK or WPA3 (Not WEP, which is outdated and may cause conflicts).
• 📡 Wi-Fi operating modeIf the router is configured to 802.11n or 802.11ac, and the laptop adapter only supports 802.11b/g, the connection will be unstable. Set the mode 802.11b/g/n (mixed).
• 🔄 Wi-Fi channelIf the channel is overloaded (for example, in an apartment building), change it to a less loaded one (use 1, 6 or 11 for 2.4 GHz).
• 🔗 MAC filtering. Check if it is blocked MAC address your laptop in the router settings.

To change router settings:

1. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (the address may differ - see the sticker on the router).
2. Enter your login and password (usually admin/admin, if you haven't changed it).

4. Save the settings and reboot the router.

6. Check for viruses and conflicting software

Viruses, firewalls, and VPN clients can block your network connection. Here's how to check:

• 🛡️ Disable your firewall and antivirus. Temporarily deactivate Windows Defender and third-party antiviruses (Kaspersky, ESET, Avast). If Wi-Fi works after this, add the network to the exceptions.
• 🔍 Check your system for viruses. Use Malwarebytes or Dr.Web CureIt! for deep scanning.
• 🌐 Disable VPNPrograms like NordVPN, ProtonVPN or built-in VPNs in browsers may conflict with network settings.
• 📦 Check installed programsSome utilities for system optimization (for example, CCleaner, Advanced SystemCare) may damage network settings.

Attention! If Wi-Fi works after disabling your antivirus, don't leave your system unprotected. Add your network adapter to your firewall exceptions or update your antivirus to the latest version.

How do I add a program to Windows Defender exclusions?

Open Windows Security → Protection from viruses and threats → Manage Settings → Adding or Removing Exceptions. Specify the path to the program file (for example, C:\Program Files\YourVPN\app.exe).

7. Hardware problems: what to do if nothing helps

If you have tried all software methods and the "Connection is limited" error persists, the problem may be in hardware:

• 🔌 Check your Wi-Fi antennasOn some laptops (for example, Lenovo ThinkPad) The antennas are connected to the adapter with thin cables. If the cable is loose or damaged, there will be no signal.
• 🔥 Adapter overheatingIf your laptop is getting very hot, the network card may be shutting down for protection. Check the temperature using HWMonitor.
• 🛠️ Adapter damageIf the laptop has been dropped or impacted, the Wi-Fi module may be damaged. In this case, replacement is the only solution.
• 🔋 Battery failure. On some models (HP Pavilion, Acer Aspire) when the battery is worn out, the system limits the power supply to the Wi-Fi adapter.

To check the hardware:

1. Connect your laptop to the router via cable EthernetIf the internet works, the problem is definitely with the Wi-Fi adapter.
2. Try connecting to a different Wi-Fi network (for example, using your phone's hotspot mode). If you can't connect to any networks, the adapter is faulty.
3. If you have USB Wi-Fi adapter, connect it to your laptop. If the network works, the built-in adapter needs repair or replacement.

Attention! If you're unsure of your skills, don't disassemble the laptop yourself—consult a service center. Damaging the antennas or adapter while disassembling may worsen the problem.

8. Alternative solutions and extreme measures

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

• 🔄 Reset Windows to factory settingsThis will remove all programs and settings, but return the system to its original state. Use this if the problem appeared after updating or installing software.
• 🖥️ Installing a clean WindowsSometimes system conflicts are so deep that only a reinstallation helps. Don't forget to back up your important data!
• 🔧 Replacing the Wi-Fi moduleIf the adapter is physically damaged, it can be replaced with a new one (costing between 1,000 and 3,000 rubles, depending on the model).
• 📡 Using an external adapter. USB Wi-Fi adapters (For example, TP-Link TL-WN725N) are inexpensive and can be a temporary or permanent solution.

Before resetting or reinstalling Windows, try creating a new user account. Sometimes the problem lies in corrupted profiles:

1. Open Parameters → "Accounts" → Family and Other Users.
2. Click Add a user to this computer and create a new user with administrator rights.
3. Log in with your new account and test your Wi-Fi connection.
