Wi-Fi is connected, but the internet isn't working on my laptop—what should I do?

You open your laptop and see that Wi-Fi is connectedThe signal is stable, but pages won't load, and there's an exclamation point next to the network icon. Sound familiar? This problem affects 7 out of 10 users at least once a year—and the causes can lie in both laptop settings and the provider's equipment. In 80% of cases, the problem can be fixed independently in 5–15 minutes, without the need for professional help.

In this article we will look at all possible scenariosWhy the internet doesn't work when Wi-Fi is active: from a simple IP address error to hidden restrictions from your internet provider. You'll learn how diagnose the problem by symptoms, which settings to check first, and what to do if standard methods don't help. We'll pay special attention Hidden Windows 10/11 settings that even IT professionals often ignore.

Before we move on to the instructions, answer one question to help narrow down the possible causes:

1. Checking basic parameters: where to start diagnostics

The first rule for any network failure is rule out obvious causesStart with simple steps that will take no more than 2-3 minutes:

• 🔄 Restart your router and laptopUnplug the router for 30 seconds, then plug it back in. Restarting your laptop will reset the temporary network settings.
• 📶 Check the indicators on the routerAre the lights on? Wi-Fi And InternetIf the internet indicator is blinking or inactive, the problem is with your provider.
• 💻 Connect another device (smartphone, tablet) to the same Wi-Fi network. If the internet works, the problem is with the laptop.
• 🔌 Try a cable connectionConnect your laptop to the router via Ethernet-cable. Does it work? So the problem is with the wireless module or its settings.

If the internet works after these steps, the problem was temporary. If not, proceed to a more in-depth diagnosis. Please note: If only the power indicator on the router is lit, and the others are off, this is a sign hardware failure (maybe the power supply or the router itself burned out).

2. Diagnosing Windows network settings: IP, DNS, and drivers

When Wi-Fi is connected but there is no internet, in 60% of cases the culprit is incorrect network parameters or a malfunctioning adapter. Let's check them one by one.

2.1 Checking the IP address and gateway

Open Command line (Win + R → enter cmd → Enter) and run the command:

ipconfig /all

Please pay attention to the following lines:

• IPv4 address: must be in the format 192.168.x.x or 10.0.x.x. If specified 169.254.x.x - This APIPA- an address that means the laptop has not received the correct IP from the router.
• Main gateway: must match the IP address of your router (usually 192.168.0.1 or 192.168.1.1).
• DNS servers: If empty or invalid values ​​are specified, sites will not open.

If the IP address starts with 169.254, run in the command line:

ipconfig /release
ipconfig /renew

2.2. Resetting the TCP/IP stack and DNS cache

Sometimes network protocols don't work correctly due to corrupted system files. Follow these steps:

netsh int ip reset
netsh winsock reset
ipconfig /flushdns

After each command, restart your laptop. This will reset all network settings to factory defaults.

What to do if commands are not executed?

If you receive an "Access Denied" error after entering the commands, run the command prompt as administrator (right-click → "Run as administrator").

2.3. Checking the Wi-Fi adapter driver

An outdated or corrupted driver is a common cause of internet problems. To check its status:

1. Click Win + X → select device Manager.
2. Expand the tab Network adapters.
3. Find the device with the names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200).
4. Right click → Properties → tab Driver.

If the status indicates "The device is working properly.", but the driver date is older than 2022 - update it through the manufacturer's official website (not through Windows Update!). For adapters Intel, Qualcomm Atheros or Realtek Download drivers only from manufacturers' websites.

Open Command Prompt (Admin)|Run ipconfig /all|Check IP address and gateway|Reset TCP/IP and DNS|Update Wi-Fi driver-->

3. Router Problems: Settings That Break the Internet

If the Internet doesn't work on other devices either, and the indicator WAN If the light on your router is blinking or goes out, the problem is with your router or ISP. Let's look at some common scenarios.

3.1. Resetting the router to factory settings

If you have recently changed your router settings (such as your Wi-Fi password, encryption type, or MAC filtering), this could lead to blocked connections. The fastest way to restore functionality is hard reset:

1. Press and hold the button Reset on the back of the router (usually a toothpick or paper clip is required).
2. Hold for 10-15 seconds until the indicators start flashing.
3. After rebooting, connect to the Wi-Fi network with the factory name (indicated on the router sticker).

⚠️ AttentionAfter the reset, you'll need to reconfigure your internet connection (enter your ISP login and password, and configure Wi-Fi). This information is usually included in your contract or on a sticker on the router.

3.2. Checking DHCP settings

If the router doesn't assign IP addresses to devices, the laptop won't be able to connect to the internet. To check the settings DHCP:

1. Go to your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section LAN or DHCP (names may differ).
3. Make sure that DHCP server is enabled and the range of addresses is not exhausted (for example, with 192.168.0.100 to 192.168.0.200).

If DHCP is disabled, enable it and save the settings. Then reconnect your laptop to Wi-Fi.

3.3. Blocking by MAC address

Some routers are configured so that only devices with allowed MAC addressesIf your laptop isn't on the list, the internet won't work. To check:

1. Find the section in the router panel MAC Filter or Wireless Mode → MAC Filtering.
2. If filtering is enabled, add the MAC address of your laptop (you can find it through ipconfig /all - line Physical address).

4. Problems on the provider's side: how to recognize and what to do

If the indicator on the router is not lit Internet Or if it's flashing yellow/red, the problem is most likely with your internet provider. Here's how to check:

• 📞 Call supportCheck if there are any accidents or scheduled maintenance in your area. Check if your account has been suspended for non-payment.
• 🔌 Connect the ISP cable directly to the laptop (without a router). If the internet works, the router is faulty.
• 📡 Check your personal account balanceSometimes providers disconnect the internet when the balance is zero, but Wi-Fi continues to work on the local network.

⚠️ Attention: if you have dynamic IP (most ISPs use this), but the router is configured with a static address, connecting to the internet will be impossible. Check the section in the router control panel WAN or Internet - parameter Connection type should be Dynamic IP (unless otherwise required by the provider).

5. Viruses and Firewall: Hidden Internet Blockers

An unlikely but possible scenario is viral activity or overly aggressive firewall settings. Here's how to check:

5.1. Virus scanning

Some viruses change network settings by redirecting traffic through a proxy or blocking DNS access. Run a full scan using system tools:

1. Open Windows Defender (Win + I → Updates and Security → Windows Security).
2. Select Protection from viruses and threats → Scanning parameters → Full scan.

If the defender doesn't find anything, but suspicions remain, use portable antiviruses like Dr.Web CureIt! or Kaspersky Virus Removal Tool.

5.2. Windows Firewall Settings

Sometimes the firewall blocks network connections, mistaking them for a threat. To check:

1. Open Control Panel → Windows Firewall.
2. Go to Allowing interaction with the application.
3. Make sure that the columns for your browser (Chrome, Firefox, etc.) are checked. Private And Public networks.

If the problem appeared after installing new software (for example, a VPN or antivirus), temporarily disable it and check the connection.

6. Alternative solutions: when standard methods don't help

If you've tried everything above and your internet still isn't working, consider these options:

• 🔧 Change Wi-Fi channelIn the router panel, find the section Wireless mode → ChannelTry installing it manually. 1, 6 or 11 (for 2.4 GHz). Channel congestion from neighboring networks can cause instability.
• 📡 Disable IPv6. In the Wi-Fi connection properties (Control Panel → Networks → Change adapter settings) uncheck Internet Protocol version 6 (TCP/IPv6).
• 🔄 Create a new connectionDelete the current Wi-Fi network in Windows settings and reconnect.
• 🖥️ Check your Windows registrySometimes the parameters get lost. TCP/IPIn the command line (admin), run:

  netsh int ipv4 reset
  netsh int ipv6 reset

⚠️ Attention: if the problem appeared after Windows updates, try rolling back to the previous version or uninstalling the latest update via Settings → Update & Security → Update History.

How to reset network settings in Windows 10/11?

Go to Settings → Network & Internet → Status → Network resetThis will remove all network adapters and reset them to factory settings. After rebooting, you'll need to reconnect to Wi-Fi.

7. Hardware malfunctions: when it’s time to contact a service center

If none of the software methods helped, it is possible hardware failureHere are signs that the problem is in the hardware:

• 💻 The Wi-Fi adapter is not detected. in the device manager (displayed with an exclamation mark or missing altogether).
• 🔌 The Internet doesn't work either via Wi-Fi or cable., but on other devices everything is fine.
• 🔥 The router is getting hot or making unusual noises. (cracking, squeaking).
• 📡 The Wi-Fi signal is extremely weak even near the router (1–2 divisions on the icon).

In these cases, self-repair is unlikely. Contact a service center, especially if:

• The laptop was dropped or subjected to impact (possible damage) Wi-Fi module or connector).
• The router is over 5 years old and has had problems with overheating in the past.

Repair cost:

• Replacing the Wi-Fi module in a laptop: from 1,500 to 4,000 ₽ (depending on the model).
• Router repair: from 1,000 to 3,000 ₽ (power supply replacement, firmware, antenna replacement).
