My laptop is connected to Wi-Fi but has no internet access: what should I do?

You open your laptop, see a familiar Wi-Fi network, enter the password – and instead of the usual access to websites, a message appears "No internet access" or a yellow triangle on the connection icon. This situation is familiar to many: the network is working, but the internet isn't working. What's the cause, and how can I restore it?

The problem may lie in the settings of the laptop itself (incorrect parameters IP, driver failure, viruses), and in the provider's equipment (router malfunction, blocking by MAC address, problems on the Internet provider's side). In this article, we will analyze all possible reasons — from banal to rare, — and we will also give step-by-step instructions For Windows, macOS, and Linux. We'll pay special attention to diagnosing the router, as in 60% of cases, the problem lies within it.

Before you start tweaking settings, check the obvious: is the internet working on other devices (smartphone, tablet, second laptop). If so, the problem is with your device. If not, the router or ISP is at fault. This simple test will save you hours of time.

1. Checking basic network settings on a laptop

Start by diagnosing your network settings directly on your laptop. Often, the problem can be resolved in just two clicks.

IN Windows open Settings → Network & Internet → StatusPay attention to the text below the name of your Wi-Fi network:

• 🔴 "No internet access" — the laptop is connected to the router, but it doesn’t distribute the Internet (or blocks your device).
• 🟡 Limited - problem with IP address or DNS.
• 🟢 "Connected", but the sites don't open - it's their fault DNS, firewall or viruses.

IN macOS open System Preferences → Network. If the status "Connected", but there is no internet, check DNS-servers (more on that below). Linux Enter the command in the terminal:

ping 8.8.8.8

If the ping goes through (64 bytes from 8.8.8.8), but the sites don't open - the problem is DNSIf there is no ping (Network is unreachable) - failure at the level IP-address or router.

2. Reboot the router and reset network settings

90% of connection problems can be solved by simply rebooting the router. Unplug it from the power outlet for 30 seconds, then plug it back in. Wait for it to fully boot up (usually takes 1-2 minutes until the indicator light comes on). Wi-Fi or Internet).

If rebooting doesn't help, do the following: resetting network settings on a laptop:

• 🪟 Windows: Settings → Network & Internet → Network reset → "Reset now".
• 🍎 macOS: Delete the Wi-Fi network in System Preferences → Network, then reconnect.
• 🐧 Linux: Run in terminal:

  sudo nmcli networking off && sudo nmcli networking on

If the problem persists, proceed to the next step - checking IP-addresses and DNS.

3. IP address issues: DHCP not providing settings

One of the most common reasons is that the laptop does not receive power. correct IP address from the router. This may occur due to a malfunction. DHCP servers (it is responsible for automatic distribution of addresses) or conflict with other devices on the network.

Check the current IP:

• 🪟 Windows: Open Command line (Win + R → cmd) and enter:

  ipconfig /all

  Look for the line IPv4 addressIf it starts with 169.254.x.x - This emergency address, meaning that DHCP didn't work.

• 🍎 macOS/Linux: In the terminal, run:

  ifconfig | grep "inet "

If IP absent or starts with 169.254, try to get it manually:

1. IN Windows open Settings → Network & Internet → Wi-Fi → Hardware settings.
2. Select "Manual" and enter:
   • IP address: 192.168.1.100 (the last digit can be any number from 2 to 254)
   • Subnet mask: 255.255.255.0
   • Gateway: 192.168.1.1 (or 192.168.0.1, look at the router sticker)
   • DNS: 8.8.8.8 And 8.8.4.4 (Google DNS)

Open command prompt|Run ipconfig /all|Check that the IP is not 169.254.xx|If necessary, enter the IP manually|Restart the laptop-->

4. DNS issues: websites don't open, but there is ping

If the laptop is connected to Wi-Fi, the ping is up to 8.8.8.8 passes, but websites don't open — are guilty DNS serversIt's like the internet's phone book: if it doesn't work, the browser doesn't know where to look.

Check it out DNS on your system:

• 🪟 Windows: Enter in the command line:

  nslookup ya.ru

  If the answer is DNS request timed out — DNS does not answer.

• 🍎 macOS/Linux: Perform:

  dig ya.ru

Solutions:

1. Change DNS manually:
   • IN Windows: Settings → Network & Internet → Wi-Fi → Change adapter settings → right-click on the connection → “Properties” → “IP version 4” → enter 8.8.8.8 And 8.8.4.4.
   • IN macOS: System Preferences → Network → DNS → add 1.1.1.1 (Cloudflare).

7. Viruses, Firewalls, and VPNs: Hidden Internet Blockers

If all settings are correct but there is still no internet, check software locks:

• 🛡️ Windows Firewall or Antivirus: Temporarily disable them and check the connection. For example, in Kaspersky or ESET NOD32 There may be a rule blocking access to the network.
• 🕵️ VPN or proxy: If you use NordVPN, ProtonVPN or proxy settings in your browser, disable them. Check in Settings → Network & Internet → VPN or Proxy.
• 🦠 Viruses and malwareSome Trojans change network settings. Scan your system. Malwarebytes or Dr.Web CureIt.

How to check your firewall:

1. Open Control Panel → Windows Firewall → Turn on or off.
2. Disable your private network firewall and check your internet connection.
3. If it works, add an exception for your browser or network.

8. Problems on the provider's side: how to check

If none of the previous methods helped, the problem may be with Internet providerHere's how to check:

• 📞 Call support: Ask if there are any accidents or scheduled work in your area.
• 🔌 Connect your laptop to the router via cableIf the internet works, the problem is in the settings. Wi-Fi router. If not, it's the ISP's fault.
• 🔄 Check your personal account balance: Sometimes providers disconnect the Internet for non-payment (even if you have an unlimited tariff).

How to contact your provider:

⚠️ Attention: If you use 3G/4G modem or USB router (for example, from Megaphone or Yota), check your balance and connection status in your personal account. Some operators block access when the traffic limit is exceeded, even if the plan is advertised as unlimited.
