Why is Wi-Fi connected but it says "No Internet Connection" — and how to fix it?

You see the familiar Wi-Fi icon with an exclamation mark and the inscription “No internet connection" or "No network access" doesn't go away despite rebooting the router? This error is one of the most common Wi-Fi problems, and it can occur in Windows 10/11, and on Android, iOS or even Smart TVThe reasons range from trivial glitches to complex network protocol conflicts.

Unlike the situation where Wi-Fi doesn't pick up the network at all, here the connection to the router There is (The device sees the network name and displays the signal strength), but there's no internet access. This means the problem isn't with the radio module or antenna, but with the router-ISP-device settings chain. We'll look into this in this article. all possible causes of this error, including rare cases where it's not your router's fault, but the equipment on your internet provider's side.

1. Checking the basic causes: router, cables, provider

Start with the simplest thing: make sure the problem isn't with your ISP or the physical connection. Users often spend hours configuring devices when a simple call to support or a cable fix would have sufficed.

The first thing to do:

• 🔌 Check the cable from your provider.: if it is damaged or not inserted properly into the port WAN (usually highlighted in blue), the router won't be able to access the internet, even if Wi-Fi is available. Try reconnecting the cable or replacing it with a known-good one.
• 📡 Reboot your routerUnplug the power supply for 30 seconds, then plug it back in. Wait until it fully boots (the indicators should be steady, not flashing).
• 📞 Check the status with your provider: Sometimes the error occurs due to line problems. Call support or check the information in your personal account (for example, Rostelecom, Beeline or MTS (Notifications about technical work are frequently displayed).

⚠️ Attention: If after rebooting the router the indicator WAN (or Internet) is off or flashing orange—the problem is definitely with your provider. Don't waste time configuring your devices.

If the error persists after these steps, proceed to the next step. If the internet works again, the issue was temporary, and you can stop here.

2. Router settings: IP, DHCP and operating modes

If the basic check doesn't help, the problem may lie in incorrect router settings. Most often, this is:

• 🔄 DHCP failure: The router does not assign correct IP addresses to devices.
• 🌐 Invalid connection type: for example, selected PPPoEwhen the provider uses Dynamic IP.
• 🔒 MAC address blocking: Some providers bind access to a specific device.

To check these parameters:

1. Connect to the router via cable or Wi-Fi (even if there is no internet, you will still have access to the settings).
2. Open your browser and enter your router's address. This is usually:
   • 192.168.0.1 (For TP-Link, D-Link)
   • 192.168.1.1 (For ASUS, Keenetic)
   • 192.168.8.1 (For Xiaomi, Tenda)

⚠️ AttentionIf the internet still doesn't work after resetting the router, your ISP may be using MAC address binding. In this case, you'll need to either provide the new MAC address to support or clone the old MAC address in the router settings (section MAC Clone).

4. DNS Issues: Why Websites Won't Open, But Wi-Fi Works

Sometimes Wi-Fi shows a connection, but browsers don't open websites, and instant messengers don't send messages. ping 8.8.8.8 in the command line it goes successfully, and ping ya.ru - No. This is a classic sign. DNS problems.

DNS (Domain Name System) is a system that resolves domain names (e.g. google.com) into IP addresses. If DNS servers don't respond, the internet is there, but websites won't open.

How to check and fix:

1. On Windows run in command line:

   nslookup ya.ru

   If the answer is "DNS request timed out", then DNS is not working.

2. Try changing DNS servers manually:

   DNS server	Addresses	Peculiarities
   Google DNS	8.8.8.8, 8.8.4.4	Fast, but may be blocked by some providers
   Cloudflare	1.1.1.1, 1.0.0.1	Good speed, supports DNS-over-HTTPS
   Yandex DNS	77.88.8.8, 77.88.8.1	Optimized for Russia, filters malicious websites
   OpenDNS	208.67.222.222, 208.67.220.220	Supports family filter

3. On Android or iOS change DNS via Wi-Fi settings:
   1. Go to network settings.
   2. Click Advanced or IP Setting.
   3. Select "Static" and enter DNS manually.

If the websites work after changing the DNS, the issue was with your provider's DNS. You can keep the new settings or contact support to troubleshoot the issue on their end.

5. Firewall, antivirus and network drivers

If you have an antivirus installed on your device (for example, Kaspersky, Avast, ESET) or firewall Windows Defender, they can block the network connection. The problem may also lie in outdated or damaged network drivers.

What to do:

• 🛡️ Disable your firewall and antivirus Wait for 5-10 minutes and check if the internet is back online. If so, set up exceptions for the network connection.
• 🔧 Update your network card drivers:
  1. On Windows: Device Manager → Network Adapters.
  2. Find your Wi-Fi adapter (e.g. Intel Wi-Fi 6 or Qualcomm Atheros).
  3. Right-click → “Update driver” → “Search automatically”.

If the driver does not update automatically, download it from the website of the laptop or network card manufacturer.

netsh int ip reset
netsh winsock reset

On Android or iOS try resetting network settings in the menu Settings → System → Reset (on Android) or Settings → General → Reset (on iPhone).

⚠️ Attention: If after updating the drivers Wi-Fi stopped working at all, roll back the driver via Device Manager → Adapter Properties → Driver → Roll Back Driver.

6. Problems on the provider's side: MAC filtering, restrictions, technical work

Sometimes the "No internet connection" error isn't caused by your devices, but by restrictions from your internet provider. Here are the most common scenarios:

• 🔒 MAC filtering: The provider has bound internet access to the MAC address of the old router or computer. After replacing the equipment, access is blocked.
• 📉 Traffic limit exceeded: If you have a tariff with a GB limit, access may be blocked after the limit is reached (this applies to mobile Internet or some home tariffs).
• 🔧 Technical work: The provider may temporarily disable services to update equipment.
• 📜 Blocking by agreement: for example, for non-payment or at the request of copyright holders (relevant for torrents).

How to check:

1. Connect your ISP's cable directly to your computer (without the router). If the internet still doesn't work, the problem is definitely with your ISP.
2. Call support and clarify:
   • Is there a MAC address binding (if yes, please provide the new MAC address of the router).
   • Has the traffic limit been exceeded?
   • Is there any maintenance being carried out?
• If used PPPoE, check if your login/password has changed (sometimes providers reset them if your payment is late).

If the problem is in MAC filtering, you can:

• Call support and ask to add a new MAC.
• Clone the MAC address of the old device in the router settings (section MAC Clone or MAC cloning).

7. Rare causes: double NAT, IPv6, Wi-Fi channel conflict

If all the previous methods fail, the problem may be more specific. Let's look at some rare but possible causes:

Double NAT: This occurs if another router is connected to the router (for example, in repeater mode). This can cause routing conflicts. The solution is to set the second router to repeater mode. AP (Access Point) or disable DHCP on it.

IPv6 issues: Some providers and routers do not work well with the protocol IPv6. Try disabling it in the router settings (section IPv6 → select "Disable").

Wi-Fi channel conflict: If there are many nearby networks on the same channel, interference may occur. Go to your router settings (Wireless Network → Channel) and select the channel manually (for example, 6 or 11 for 2.4 GHz). For 5 GHz, select a channel with less traffic (you can check this using the app) Wi-Fi Analyzer on Android).

Incompatibility of Wi-Fi standards: if the router is operating in mode 802.11n/ac/ax, and the old device only supports 802.11b/g, problems may arise. The solution is to set the mode in the router settings 802.11b/g/n mixed.
