Why is my laptop's Wi-Fi not working? A full breakdown of the causes and solutions.

You've connected to your home or public Wi-Fi network, but instead of accessing websites as usual, you see a yellow triangle with an exclamation mark and the message "No internet access»? This problem is familiar to most laptop users. Windows 10/11, macOS and even LinuxI have a network signal, but pages won't load, messengers are disabled, and network diagnostics aren't helping. What's wrong, and how can I get it working again?

In this article we will look at All possible reasons for the lack of internet access with an active Wi-Fi connection — from trivial router failures to hidden operating system settings. You'll learn how to distinguish a problem with your provider from a laptop malfunction, which commands to run first, and when it's time to call support. No fluff—only proven solutions with explanations for users of all skill levels.

1. The problem is with the provider or router.

Before messing with your laptop's settings, make sure the internet actually works on other devices. Take your smartphone, tablet, or second computer and check the connection to the same Wi-Fi network. If the internet is down everywhere, the problem is either provider, or router.

🔹 How to check:

• 📱 Phone/tablet: Connect to the same Wi-Fi. Can you access websites? If not, the problem isn't with the laptop.
• 🖥️ Cable connection: connect the laptop to the router via Ethernet-cable. Is it working? That means there's a problem with the router's Wi-Fi module or its settings.
• 🔄 Reboot: Unplug the router for 30 seconds, then plug it back in. Wait until it fully boots up (all indicators should be steady).

If the internet works after rebooting the router, the problem was temporary. Otherwise:

• 📞 Check your account balance with your provider (sometimes access is blocked for non-payment).
• 🛠️ Make sure the cable from your ISP is securely connected to the port WAN (usually it is highlighted in a different color).
• 🌐 Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1) and check your internet connection status. If there is an error like "No Internet" or "DHCP failed" — call your provider's support team.

⚠️ Attention: The settings of the router web interface may differ depending on the model (TP-Link, ASUS, Keenetic etc.). Logins and passwords for entry are usually indicated on a sticker on the device body.

2. IP address failure: DHCP is not providing settings

One of the most common reasons for the lack of internet connection when connected to Wi-Fi is incorrect network settings, namely problems with obtaining IP addressesUsually, the router automatically assigns addresses to devices via the protocol DHCP, but sometimes this process fails. As a result, the laptop connects to the network but cannot exchange data with the internet.

🔹 How to fix:

1. Click Win + R, enter ncpa.cpl and press EnterThe window "Network connections».
2. Find your wireless connection (usually called "Wireless network" or "Wi-Fi”), right-click on it and select “Properties».
3. In the list of components, find "Internet Protocol version 4 (TCP/IPv4)" and double-click on it.
4. Make sure the options "Obtain an IP address automatically" And "Obtain DNS server address automatically" If not, check the boxes and save the settings.

If the Internet still doesn't work after this, try manually enter DNS (for example, from Google or Cloudflare):

• 🔢 Preferred DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
• 🔢 Alternative DNS: 8.8.4.4 or 1.0.0.1.

If this doesn't help, try release and renew IP via command line:

ipconfig /release
ipconfig /renew

⚠️ Attention: If after manually setting the IP address (for example, 192.168.1.100) the internet started working, but after a while it disappeared again - the problem is definitely in the settings DHCP on the router. It's possible there's a filter enabled there. MAC addresses or the number of connected devices is limited.

3. The Wi-Fi adapter driver is outdated or corrupted.

Drivers are programs that enable the operating system to communicate with the hardware. If a Wi-Fi adapter driver is outdated, corrupted, or conflicts with other components, the laptop may connect to the network but not access the internet. This is especially true after an update. Windows or reinstalling the system.

🔹 Signs of a driver problem:

• 🔌 In the Device Manager, there is an exclamation mark next to the adapter.
• 🔄 Wi-Fi periodically disconnects or works unstable.
• 🛠️ The connection properties say "Limited" or "No network access».

🔧 How to update or reinstall the driver:

1. Click Win + X and select "device Manager».
2. Expand the branch "Network adapters", find your Wi-Fi module (usually the name contains the words Wireless, Wi-Fi, 802.11 or a brand, for example, Intel, Qualcomm, Broadcom).
3. Right click on the adapter and select "Update driver» → «Automatic search».
4. If updating does not help, uninstall the driver ("Remove device"), then restart your laptop. The system should reinstall the driver.

If automatic methods do not work, download the driver manually from the official website of the laptop manufacturer (HP, Lenovo, Dell, ASUS etc.) or adapter. To do this:

1. Find out the adapter model in the device manager (right click → "Properties» → tab «Intelligence» → property «Equipment ID»).
2. Copy the first lines from the section "VEN" And "DEV" (For example, VEN_8086 And DEV_2723) and find the driver using these codes on the website PCIDatabase.

4. Network Conflict: Connection Priority

Windows (especially versions 10 and 11) sometimes gets confused about network priorities if you've connected to multiple Wi-Fi hotspots. For example, the laptop might get stuck on an old network with limited access or try to use VPN/proxy, which are now not working. As a result, there is a connection, but no traffic.

🔹 How to check network priority:

1. Open "Parameters» (Win + I) → «Network and Internet» → «Wi-Fi».
2. Click "Managing known networks».
3. Delete all unnecessary networks (especially those you haven't connected to for a long time).
4. Restart your laptop and reconnect to the desired network.

If the problem persists, check your settings interface metrics (connection priority):

1. Open Command Prompt as Administrator (Win + X → «Terminal (administrator)»).
2. Enter the command:

   netsh interface ipv4 show interfaces

   Please pay attention to the column "Metrics"The lower the number, the higher the priority.

3. If your Wi-Fi metric is high (for example, 50), lower it with the command:

   netsh interface ipv4 set interface "Interface_Name" metric=10

   (replace "Interface_name" with the name of your adapter from the previous step).

It's also worth turning off everything VPN-connections and proxy servers:

• 🔗 VPN: «Parameters» → «Network and Internet» → «VPN» → delete all profiles.
• 🌐 Proxy: «Parameters» → «Network and Internet» → «Proxy» → disable «Use a proxy server».

5. A firewall or antivirus is blocking access

Sometimes built-in firewall Windows or a third-party antivirus (Kaspersky, ESET NOD32, Avast) mistakenly blocks the network connection, believing it to be unsafe. This can happen after updating the program or changing its settings. As a result, Wi-Fi connects, but traffic is blocked.
