Wi-Fi is connected, but the internet is not working: full diagnostics and solutions

Do you see the Wi-Fi connection icon on your device, but pages won't open, messaging apps won't update, and videos are stuck loading? This situation is familiar to every second user. The Internet drops out even though Wi-Fi is working., and the causes could lie in both the router settings and issues with the provider. Unlike a complete lack of signal, this is more difficult to diagnose: the connection is there, but traffic isn't being transmitted.

In this article we will look at all possible scenarios — from a simple IP address error to hidden restrictions from your internet provider. You'll learn how Distinguish between a router-related issue and a device or service provider issue, and get checklists for quick troubleshooting. We'll pay special attention to cases where the internet works on some devices and not on others—this is a key symptom for an accurate diagnosis.

1. Checking basic parameters: where to start diagnostics

Before digging deep into your router settings or calling your provider's support, please do the following: initial checkIt takes no more than 5 minutes, but will help eliminate 60% of common problems:

• 🔄 Reboot your routerUnplug it for 30 seconds, then plug it back in. This will clear the DHCP cache and any temporary errors.
• 📱 Check other devicesConnect your smartphone, tablet, or laptop to the same network. If the internet works on them, the problem lies with your primary device.
• 🌐 Test different websitesSometimes individual resources are blocked (for example, VKontakte or YouTube), and the rest of the Internet works.
• 🔌 Connect via cableIf the internet appears with a wired connection, the router's Wi-Fi module or its settings are to blame.

If the problem persists after these steps, proceed to detailed diagnostics. Please note: if the internet is not working on one device only, and on the rest everything is fine, the reason must be sought in the settings of this gadget (more about this in section 4).

2. Router-side issues: settings and hardware failures

The router is the weakest link in the chain. Even if the Wi-Fi indicator is green, it doesn't guarantee proper internet operation. Let's look at common problems:

2.1 DHCP Failure: Devices are not receiving an IP address

If your device connects to Wi-Fi but an exclamation mark appears next to the network name (on Windows) or the message "No Internet access" is most likely not given by the router IP address. Check this out:

1. On Windows: open Command line and enter

   ipconfig /all

   . Look for the line IPv4 address. If there 169.254.x.x — DHCP is not working.
2. On Android/iOS: Go to Wi-Fi settings, click on your network and look at the IP address. The result is similar (169.254.x.x) will point out the problem.

Solutions:

• ⚡ Manually restart DHCP on the router via the web interface (usually in the section LAN or DHCP).
• 🔧 Set up a static IP on your device (if you know your network settings).
• 🔄 Reset your router to factory settings (button Reset on the back panel).

2.2. Incorrect DNS settings

If the sites do not open, but Skype or Telegram they work - they are to blame DNS serversThe router may be using incorrect addresses or they may be blocked by your ISP. Check:

ipconfig /flushdns

To change DNS on your router:

1. Go to the web interface (usually 192.168.0.1 or 192.168.1.1).
2. Find the section Internet or WAN.
3. In the field DNS enter 8.8.8.8 And 1.1.1.1.
4. Save the settings and reboot the router.

3. Internet service provider problems: how to recognize them and what to do

If the internet doesn't work on all devices, including those connected via cable—the problem is most likely on the provider's side. But how can you check this?

3.1. Ping to the provider's gateway

Open Command line and enter:

ping 8.8.8.8

If the packets don't arrive (The specified node is unavailable), Means:

• 🔌 There is no physical connection with the provider (cable break, problems with the PBX).
• 🔒 The provider is blocking traffic (for example, for non-payment).
• 🛠 Failure on the provider's equipment (can only be resolved by calling support).

3.2. Checking service status

Many providers have service status pages (eg. Rostelecom, Beeline, MTS). Find it by searching for "provider name "Service status." If it says maintenance is ongoing, all you can do is wait.

3.3. Blocking by MAC address

Some providers (especially in office tariffs) tie the Internet to MAC address Devices. If you've changed your router or connected a new device directly, access may be blocked. Solutions:

• 📞 Call support and provide the new MAC address (indicated on the router sticker or in the settings) WAN).
• 🔧 Clone the MAC address of the old device in the settings of the new router (option MAC Clone).

⚠️ Attention: If the provider uses PPPoE, L2TP or PPTP, check the login and password in your router settings. Authorization errors are a common cause of no internet connection when connected to Wi-Fi.

4. Device-specific issues: Windows, Android, iOS

If the internet is not working on only one device (for example, a laptop or smartphone), while the others are connected normally, look for the problem in its settings.

4.1. Windows: Reset network settings

IN Windows 10/11 A common cause is a network stack failure. This is how to fix it:

1. Open Settings → Network & Internet → Status.
2. Click Network reset.
3. Restart your computer.

If this does not help, check:

• 🔧 Wi-Fi adapter driverUpdate it through device Manager.
• 🛡 Firewall or antivirus. Temporarily disable them (for example, Kaspersky or Avast may block traffic).

4.2. Android/iOS: Reset network settings

On mobile devices, the problem is often solved by resetting network settings:

• 📱 Android: Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth.
• 🍎 iPhone: Settings → General → Transfer or reset → Reset network settings.

After resetting, you will have to re-enter your Wi-Fi passwords, but this often solves connection problems.

5. IP address conflicts and double NAT

If you have a second router in your network (for example, from a provider + your personal one), problems may arise IP conflict or double NATThis results in devices connecting to Wi-Fi, but the internet not working.

5.1 How to recognize double NAT

Signs:

• 🔢 In the router settings, the WAN-IP starts with 192.168.x.x or 10.x.x.x (this is a local address, not an external one).
• 🔄 Online games or IP cameras are not working due to port forwarding issues.

5.2. Solutions

Correction options:

1. Disable DHCP on the second router and use it as an access point.
2. Set up a bridge on the main router (if your provider allows it).
3. Change the subnetFor example, if the first router distributes 192.168.1.x, install on the second one 192.168.2.x.

⚠️ Warning: If you use IPTV From your provider, disabling the second router may disrupt your TV service. In this case, configure VLAN for IPTV on the main router.

6. External interference and restrictions: from neighbors to government blocking

Sometimes the problem isn't your hardware at all. Let's consider external factors:

6.1. Wi-Fi channel overload

If you have 2.4 GHz If your router is connected to a network, and there are many networks in the area, the channel may be overloaded. Check:

• 📡 Use the app Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) for channel load analysis.
• 🔄 Change the channel in your router settings (optimally 1, 6, or 11 for 2.4 GHz).
• 🚀 Go to 5 GHz, if your router supports this range.

6.2. Traffic blocking by the provider or Roskomnadzor

If only certain websites do not open (for example, Telegram, Twitter or torrents), the following are possible:

• 🔒 Blocked by RoskomnadzorCheck through register of prohibited websites.
• 📉 Provider throttling (artificial slowdown of certain services).
• 🛡 Parental Control (if enabled on the router).

Solutions:

• 🔗 Use VPN (For example, ProtonVPN or Warp from Cloudflare).
• 🔧 Change DNS to 1.1.1.1 (Cloudflare) or 77.88.8.8 (Yandex).

7. Hardware failures: when it's time to replace your router

If all software methods have been tried and the Internet still doesn't work, it's possible hardware failureSigns:

• 🔥 The router gets very hot or shuts down.
• 📶 The Wi-Fi signal disappears at a distance of more than 2 meters.
• 🔌 The Internet only works via cable, and does not distribute Wi-Fi.

7.1. Troubleshooting

Check:

1. NutritionTry a different power supply (if it is removable).
2. PortsConnect the cable to another LAN port of the router.
3. AntennasIf they are removable, tighten them carefully.

7.2 When repair is not practical

If the router is more than 5 years old and its maximum speed is 150 Mbps, it's easier to buy a new one. Modern models (for example, TP-Link Archer AX21 or Keenetic Speedster) support Wi-Fi 6 and cope with the load better.

⚠️ Attention: If the router displays an error "WAN port is not connected", but the cable is inserted—this is a sign of a faulty port. In most cases, repairing it is not cost-effective.
