My laptop is connected to Wi-Fi, but the internet isn't working: A complete guide to diagnostics and repairs.

The laptop is connected to Wi-Fi, the network indicator shows a stable signal, but pages won't load, instant messaging apps won't sync, and the system returns the "No internet access" error. The problem could be related to the network adapter settings, router settings, or an internet service provider (ISP) issue. Before contacting support, check the basic settings: other devices on the same network are working, the IP address and DNS are correct, and there are no blocks from antivirus or firewall software. Continue reading the article: detailed analysis of the reasons non-working internet with active Wi-Fi and step-by-step solutions for Windows, macOS, and Linux, including command-line diagnostics and network reset.

It's important to understand that the lack of internet access with Wi-Fi active is not a single problem, but a whole range of possible malfunctions. For example, your ASUS ZenBook may not receive an IP address from the router, but MacBook Pro — blocking traffic due to incorrect firewall settings. We've structured this material so you can quickly find a solution for your specific situation without wasting time trying every option.

We'll start with the simplest and most obvious causes, which can be resolved in a couple of clicks, and then gradually move on to more complex technical nuances. If you're unsure, don't worry: each section contains detailed screenshots (for Windows) and terminal commands (for macOS/Linux), as well as warnings about potential risks.

1. Checking basic parameters: router, provider, device

Before digging into your laptop's settings, make sure the problem isn't with your hardware or service provider. These steps take no more than 5 minutes but will save you hours of troubleshooting.

• 🔌 Reboot your routerUnplug it for 30 seconds, then plug it back in. Wait until it fully boots up (all lights should be steady). This solves 40% of connection issues.
• 📡 Check the internet on other devicesIf your smartphone or tablet also won't connect to the internet, the problem lies with your router or ISP. If your laptop isn't working, we'll look for the cause there.
• 💡 Make sure your internet bill is not overdue.Log in to your provider's account or call support. Some providers block access if you're in arrears, but leave Wi-Fi active.
• 🔄 Try connecting to a different networkIf your neighbors have open Wi-Fi or a mobile hotspot, check if the internet works through them. This will help rule out hardware issues with your laptop.

If the internet works after these steps, the problem was temporary. If not, we'll move on to a more in-depth diagnosis. Please note: if no device in the house connects to the internet, There's a 95% chance your router or ISP is to blame—call technical support..

2. Diagnosing network settings on a laptop (Windows)

Windows 10 and 11 have built-in network diagnostic tools, which are often ignored. However, they can automatically fix most software problems.

Open Settings → Network & Internet → Status and click "Network reset" This feature will reset all network settings to factory defaults, deleting saved networks and VPNs. Attention: After the reset, you will have to re-enter your Wi-Fi passwords!

In the command line (Win + R → cmd), run the following in turn:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

If the commands didn't help, check IP settings:

1. Go to Control Panel → Network and Sharing Center → Change adapter settings.
2. Right-click on your Wi-Fi adapter → Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
4. Make sure that the "Obtain an IP address automatically" and "Obtain DNS server address automatically" boxes are checked.

⚠️ AttentionIf you manually entered the IP address (for example, for a corporate network), write it down before resetting - you will have to restore it later.

Make sure airplane mode is turned off

Run the Network Troubleshooter

Reset TCP/IP stack via command line

Check IP settings (automatic DHCP)

Reinstall the Wi-Fi adapter driver-->

3. DNS issues: why websites don't open even when the connection is working

A common situation: Wi-Fi is connected, the network icon shows internet access, but the browser returns errors like "DNS_PROBE_FINISHED_NXDOMAIN" or "ERR_NAME_NOT_RESOLVED." This means that your laptop cannot resolve domain names (e.g. google.com) into IP addresses.

The solution is to change your DNS servers. Here's how:

• 🌍 Google Public DNS: 8.8.8.8 And 8.8.4.4
• 🛡️ Cloudflare DNS: 1.1.1.1 And 1.0.0.1
• 🇷🇺 Yandex.DNS: 77.88.8.8 And 77.88.8.1

Instructions for Windows:

1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Right-click on Wi-Fi → Properties → Internet Protocol Version 4 (TCP/IPv4) → Properties.
3. Select "Use the following DNS server addresses" and enter the selected values.
4. Click OK and restart your laptop.

For macOS/Linux, edit the file /etc/resolv.conf Or use the graphical interface in the network settings. After changing the DNS, test the connection with the command:

ping 8.8.8.8
nslookup google.com

If ping passes, and nslookup No, the problem is definitely DNS. If both aren't working, look deeper for the cause.

4. IP address conflicts and DHCP failures

If you have multiple devices on your network, your router may assign two of them the same IP address (for example, 192.168.1.100). This results in one of the devices losing internet access, even though Wi-Fi is connected. Problems also arise if the DHCP server on the router is not working correctly.

You can check for an IP conflict like this:

1. Open Command Prompt (Win + R → cmd).
2. Enter ipconfig /all and find the line "IPv4 address".
3. Compare this address with the IP of other devices on the network (you can go to the router's web interface and see the list of connected clients).

If a duplicate is found, run:

ipconfig /release
ipconfig /renew

If the router does not issue an IP at all (in ipconfig you see an address like 169.254.x.x), then DHCP is disabled or has failed. Solutions:

• 🔄 Reboot your router.
• 🖥️ Go to the router's web interface (usually 192.168.1.1 or 192.168.0.1) and check if the DHCP server is enabled.
• 🛠️ Assign IP manually: in the IPv4 properties, specify an address from your network range (e.g. 192.168.1.150), mask 255.255.255.0, gateway 192.168.1.1.

⚠️ Attention: If you assign a static IP, make sure it is not in the router's DHCP range (for example, if DHCP hands out addresses with 192.168.1.100 By 192.168.1.200, take the IP below 100 or higher 200).

5. Driver and hardware problems

If all the settings are correct, but the internet still doesn't work, it might be the culprit Wi-Fi adapter or its driver. This is especially relevant for laptops with Realtek or Broadcom adapters that are known to fail.

How to check:

1. Open device Manager (Win + X → Device Manager).
2. Expand the “Network adapters” branch and find your Wi-Fi module (for example, Intel Wi-Fi 6 AX200).
3. If there is a yellow exclamation mark next to the name, the driver is not working properly.

Solutions:

• 🔄 Update your driverRight-click on the adapter → Update driver → Search automatically.
• 🗑️ Uninstall and reinstall the driverSelect "Remove device", then from the menu "Action" → "Scan for hardware changes".
• 💿 Install the driver from the manufacturer's website. For Dell XPS download from support.dell.com, For HP Pavilion - With support.hp.com.
• 🔧 Check the hardware Wi-Fi buttonOn some laptops (for example, Lenovo ThinkPad) there is a physical switch or a key combination (Fn + F2) to turn Wi-Fi on/off.

For macOS:

• Open About This Mac → System Report → Network → Wi-Fi and check the adapter status.
• Reset the SMC (for Intel Macs) or T2 (for Apple Silicon) - instructions on the Apple website.

If after all these steps the Wi-Fi still doesn't work, the adapter itself may be faulty. In this case, the only solution is module replacement or using an external USB adapter.

How to check a Wi-Fi adapter for physical damage?

Unplug your laptop and remove the battery (if removable). Remove the back cover and locate the Wi-Fi module—usually a small board with antennas attached to a connector. M.2 or mPCIeCheck that the antenna wires (they're thin, black/white) aren't disconnected. If the module is swollen or shows signs of oxidation, it needs to be replaced.

6. Firewall, antivirus and other programs that block the network

Sometimes the internet doesn't work because of overly aggressive security settings. Windows Firewall, antivirus software (Kaspersky, Avast, ESET) or VPN clients (NordVPN, ProtonVPN) may block network traffic.

How to check:

• 🛡️ Temporarily disable the firewall:
  1. Open Control Panel → Windows Firewall → Turn firewall on or off.
  2. Check "Disable firewall" for both private and public networks.
  3. Try opening the website. If it works, the problem is in your firewall rules.
• 🦠 Disable your antivirusFind its icon in the tray (next to the clock), right-click and select "Disable Protection" or "Pause."
• 🌐 Check your VPNIf you use a VPN, turn it off and try accessing the network without it. Some VPNs (for example, OpenVPN) can “break” routing.

If the internet works after disabling protection, add exceptions for the browser and network services in your antivirus or firewall settings. For Windows:

1. Open Windows Firewall → Advanced settings.
2. Go to Outbound Rules → Create Rule.
3. Select "For the program", specify the path to chrome.exe or firefox.exe, allow the connection.

⚠️ AttentionDon't leave your firewall and antivirus software disabled for long periods of time—this puts your laptop at risk of virus infection. Re-enable your protection immediately after testing.

7. Router-level issues: settings, firmware, channels

If the internet is only down on your laptop, but everything works fine on other devices, the problem is most likely with the laptop itself. However, if the connection drops on all devices, the router is to blame. Let's look at the main problems:

Problem	Signs	Solution
Outdated firmware	Frequent interruptions, slow speed, some functions do not work	Update the firmware via the router's web interface (System Tools section)
Wi-Fi channel congestion	The network comes and goes, especially in the evening	Change the Wi-Fi channel to 1, 6, or 11 (in the wireless network settings)
DHCP is disabled	Devices connect to Wi-Fi but do not receive an IP address (169.254.xx type)	Enable the DHCP server in your router's LAN settings.
MAC address filtering	Only some devices do not connect to the internet	Disable filtering or add the laptop's MAC address to the list of allowed ones.
Incorrect Wi-Fi operating mode	The laptop doesn't see the network or connects, but without internet.	Set the mode 802.11n/ac (or b/g/n for older devices)

To access your router settings:

1. Find out its IP address (usually found on a sticker on the bottom or in the instructions). Popular options: 192.168.1.1, 192.168.0.1, 192.168.8.1.
2. Enter this address into the address bar of your browser.
3. Enter your login and password (by default it is often admin/admin or admin/empty).
4. Go to the wireless network section (Wireless) and check the settings.

If your router is showing errors or not responding to changes, reset it to factory settings (button Reset (on the back panel). After the reset, you'll need to reconfigure your internet connection (your provider's details are usually included in your contract).

8. Alternative connection methods and extreme measures

If none of the above helps, try alternative connection methods or more radical solutions:

• 🔗 Connect via cableConnect your laptop to the router via Ethernet and check if the internet is working. If so, the problem is definitely with the Wi-Fi adapter or its settings.
• 📶 Use mobile internetEnable the hotspot on your smartphone and connect to it from your laptop. This will help determine whether the ISP is at fault.
• 🔄 Reset the network to factory settings (Windows 10/11: Settings → Network & Internet → Status → Network reset).
• 🖥️ Reinstall the operating systemA last resort if all else fails. System files may be damaged by a virus.
• 🛠️ Contact the service centerIf your laptop is under warranty, do not disassemble it yourself—this may void the warranty.

If you suspect hardware failure Wi-Fi module, but don't want to take your laptop in for repair, you can temporarily use USB Wi-Fi adapter (costs from 500 rubles). Connect it to a USB port, install the drivers, and you'll be able to access the internet again.

For owners MacBook For Wi-Fi problems, Apple offers a special diagnostic program - Wireless DiagnosticsRun it through Spotlight (click Cmd + Space and enter the name). The program will analyze the network and suggest solutions.

FAQ: Frequently asked questions about the problem

Question 1: My laptop connects to Wi-Fi, but it says "No internet access." What should I do?

Answer: Start by rebooting your router. Then check your IP settings (they should be set to "Obtain Automatically") and change your DNS to 8.8.8.8If this doesn't help, reset the TCP/IP stack with the command netsh int ip reset.

Question 2: Wi-Fi stopped working after a Windows update. How can I fix it?
