There's Wi-Fi, but no internet: Why this happens and how to restore network access

The situation is familiar to many: the Wi-Fi icon with signal bars proudly appears in the notification bar, but the browser stubbornly displays the "No Internet Connection" error, and instant messaging apps stop updating. There is a network connection, but there is no internet — one of the most common problems for both beginners and experienced users. Causes can lie in router settings, provider issues, IP address conflicts, or even a simple failure to pay a bill.

In this article we will look at all possible scenarios, why Wi-Fi is connected but the internet isn't working - from trivial to rare. You'll get step-by-step instructions for Windows, Android, iOS, Smart TV and routers of popular brands (TP-Link, ASUS, Keenetic, MikroTik). And you will also learn how diagnose the problem in 2 minutes and not waste time on useless actions.

⚠️ Important: If the internet connection is lost on all devices (phone, laptop, TV), the problem is almost certainly with the router or ISP. If it's only on one device, the settings on that device are to blame.

1. Checking the obvious: payment, cables, indicators

Before digging into the settings, rule out trivial causes. Start with the simplest:

  • 💳 Check your personal account balance From your provider. Even if autopayment is set up, sometimes the debit doesn't go through. Log in to your account or call support—it only takes a minute.
  • 🔌 Inspect the cablesIf the router is connected to the Internet via WAN-port (usually highlighted in blue), make sure the cable is firmly inserted at both ends. The indicator on the router box should be lit. Internet or WAN (green/blue - normal, red/orange - problem).
  • Reboot your routerUnplug the power cord for 30 seconds and then plug it back in. This solves the problem in 40% of cases, especially if the router has been running without rebooting for more than a week.

If after reboot the indicator Internet If the light on the router doesn't light up or is blinking orange, the problem is on the provider's side. In this case, call support - you won't be able to fix anything on your own.

2. Diagnostics on the device: Windows, Android, iOS, Smart TV

If Wi-Fi is connected but the internet is not working on just one device, the problem lies in its settings. Let's look at each platform.

🖥️ Windows 10/11

Open Start → Settings → Network & Internet → StatusPlease pay attention to the point Network Adapter:

  • If there is a note next to Wi-Fi No internet access, try it disconnect and reconnect the network (click on the Wi-Fi icon in the tray → “Forget this network” → connect again).
  • If the status Connected, protected, but the internet doesn't work, run the commands in Command line (run as administrator):
netsh winsock reset

netsh int ip reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

After each command, press EnterThen restart your PC.

📱 Android and iOS

On mobile devices, the following usually helps:

  • 🔄 Reconnecting to the network: Go to Wi-Fi settings, tap on your network → “Forget” → connect again.
  • 📶 Reset network settings (Android: Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth). On iPhone: Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
  • 🛠️ DNS check: install the application DNS Changer (Android) or 1.1.1.1: Faster Internet (iOS) and select a public DNS (eg. 8.8.8.8 from Google).

📺 Smart TV (Samsung, LG, Sony, Xiaomi)

On TVs the problem is often related to incorrect IP settings. Log in to:

  • 📺 Samsung: Settings → General → Network → Open network settings → Wi-Fi → select your network and click “Connect”.
  • 📺 LG: Settings → All settings → Network → Wi-Fi connection → "Advanced settings" → install Obtain an IP automatically.
  • 📺 Xiaomi: Settings → Network & Internet → Wi-Fi → long click on the network → “Change network” → “Show advanced settings” → set DHCP.

3. Router problems: settings, firmware, conflicts

If the internet doesn't work on all devices, the router is to blame. Let's look at the main causes and solutions.

🔧 Incorrect WAN settings

Go to your router's control panel (usually at 192.168.0.1 or 192.168.1.1>, login/password — admin/admin). Go to the section Internet or WAN and check:

  • 📡 Connection type: must match what the provider specified (Dynamic IP, PPPoE, Static IP etc.).
  • 🔐 Login/Password (For PPPoE): enter the data from the contract with the provider.
  • 🌐 DNS servers: try specifying public (8.8.8.8 And 8.8.4.4 from Google or 1.1.1.1 from Cloudflare).

🔄 IP address conflict

If the router distributes IP addresses in the range 192.168.1.1–192.168.1.100, and your device is configured to a static IP outside this range (for example, 192.168.1.150), conflict is inevitable. Solution:

  1. Go to your router settings → DHCP → expand the address pool (for example, to 192.168.1.200).
  2. Or set the device to obtain an IP automatically (DHCP).

🖥️ Outdated firmware

Your router firmware may contain bugs that can cause internet instability. Update it:

  1. Download the latest firmware version from the manufacturer's website (TP-Link, ASUS and others).
  2. Go to your router's control panel → System tools or AdministrationFirmware update.
  3. Download the file and wait until it is completed (do not turn off the router!).
What should I do if my router won't turn on after updating the firmware?

If your router stops responding to the power button or won't boot after updating the firmware, try resetting it to factory settings. To do this, press and hold the power button. Reset (usually hidden in a hole on the rear panel) for 10-15 seconds. If this doesn't help, you may need to take the router to a service center for a JTAG reflash.

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

Sometimes it's not your router or device that's at fault, but your ISP. Here's how to determine that:

  • 📞 Call support and ask if there is accidents on the line or planned workCheck if your IP has been blocked for suspicious activity (this can happen when using torrents).
  • 🔌 Connect the cable directly to the PC (bypassing the router). If the internet works, the problem is with the router. If not, the ISP is to blame.
  • 📡 Check the MAC addressSome providers bind the internet connection to the device's MAC address. If you've changed your router, the new MAC address may not be registered. Solution: clone the old router's MAC address in the new router's settings (section MAC Clone or MAC cloning).

⚠️ Attention: If the provider uses technology PPPoE or L2TP, make sure your login and password are entered correctly. Sometimes, after changing your plan, your data changes, but the provider doesn't notify you.

Symptom Probable cause Solution
There is Internet on the PC (via cable), but not on Wi-Fi. Incorrect router settings or IP conflict Reset your router to factory settings or check DHCP
Wi-Fi is connected, but the pages don't load, and Skype/Telegram work. DNS issues or blocked ports Change DNS to 8.8.8.8 or use a VPN
The Internet disappears at a certain time (in the evening, at night) Provider network congestion or tariff limits Call support or check your traffic limits.
Wi-Fi works, but the speed is extremely slow (0.1–1 Mbps) Throttling by the provider or interference on the channel Try changing the Wi-Fi channel in your router settings.

5. Access blocking: antivirus, firewall, parental control

Sometimes the internet is blocked programmatically. Check:

  • 🛡️ Antivirus or firewall: temporarily disable protection (eg. Kaspersky, Avast, Windows Defender) and check your connection. If the internet works, add your browser to the exceptions list.
  • 👨‍👩‍👧‍👦 Parental control: in routers ASUS, TP-Link And Keenetic There's a feature for restricting access by time or device. Go to the control panel → Parental control and check the rules.
  • 📱 VPN or proxy: if you use a VPN (NordVPN, ProtonVPN), disable it. Sometimes VPN servers are overloaded or blocked.

⚠️ Attention: On some routers (MikroTik, Zyxel Keenetic) the function can be enabled MAC address filteringIf your device isn't whitelisted, the router will block it from accessing the internet, even if it's connected to Wi-Fi.

6. Wi-Fi signal interference and problems

If Wi-Fi is connected, but the Internet sometimes appears and then disappears, it is the fault of interference or weak signalHere's what to do:

  • 📶 Change Wi-Fi channel: go to your router settings → Wireless modeChannel settings. Instead of Auto select a channel manually (eg 6 or 11 for 2.4 GHz). Use the app Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to find the least congested channel.
  • 🔄 Switch to 5 GHz: If your router supports dual-band Wi-Fi, connect to the network with the suffix 5GThere is less interference in this range, but the signal penetrates walls worse.
  • 📡 Reduce the transmit power: If the router is located near a microwave or other sources of interference, reduce the Wi-Fi power in the settings (section Wireless Mode → Transmission Power).
  • 🔌 Use a repeater or mesh system: If the signal is weak in some rooms, install a repeater (TP-Link RE605, Xiaomi Mi Wi-Fi Repeater) or switch to the Mesh system (Google Nest Wi-Fi, ASUS ZenWiFi).

⚠️ Attention: If you live in an apartment building, there's a good chance your neighbors are using the same Wi-Fi channel as you. This leads to ether overload and a drop in speed. The solution is to switch to a less congested channel or use 5 GHz.

7. Rare causes: from IPv6 to viruses

If none of the above helps, check:

  • 🌐 IPv6: Some providers don't support IPv6, but it may be enabled in your router or device settings. Disable it in the router control panel (section LAN or IPv6).
  • 🐛 Viruses or malware: scan your device Malwarebytes or Dr.Web CureIt!Some viruses change network settings.
  • 🔌 Power supply problemsIf your router is connected through a power strip or surge protector, try plugging it directly into a wall outlet. Unstable power can cause problems.
  • 📡 Incompatibility of Wi-Fi standards: If you have an old router (for example, TP-Link TL-WR740N), it may not support modern Wi-Fi 6 devices. The solution is to update the firmware or buy a new router.

⚠️ Attention: If you use double NAT (for example, connecting one router to another) can cause internet problems. Disable DHCP on the second router or set it to DHCP mode. bridge.

8. If all else fails: radical measures

If you've tried everything but the internet still isn't working, there are some radical options left:

  • 🔧 Resetting the router to factory settings: click Reset for 10-15 seconds. After this, the router will return to its default settings, and you can configure it again.
  • 📞 Replacing the router: If the router is older than 5 years, it may simply fail. Modern models (TP-Link Archer AX6000, ASUS RT-AX88U) support new Wi-Fi standards and are less likely to glitch.
  • 🔄 Changing providersIf internet problems occur regularly, it might be worth considering an alternative provider. Check reviews of connection quality in your area.

⚠️ Attention: Before resetting the router, save the settings (if this option is available in the control panel) or take a photo of the key parameters (login/password for connecting to the provider, Wi-Fi settings).

FAQ: Frequently Asked Questions

🔍 Why is Wi-Fi connected, but the internet only works in some apps (for example, in Telegram, but not in the browser)?

This is a sure sign of a problem with DNS serversBrowsers and some apps use DNS to resolve website names to IP addresses. If the DNS isn't responding, pages won't load, but instant messaging apps (which often use direct IP connections) will work. Solution: Change your DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in the router or device settings.
