Wi-Fi is working, but there's no internet: Complete instructions for restoring access

Do you see the familiar Wi-Fi connection icon on your device, but browser pages won't open, and instant messaging apps show a connection error? This situation is familiar to every second home network user. According to statistics, NetSpot43% of Wi-Fi problems are related to a lack of internet access while still connected to the network. The causes can lie in both the router settings and the settings of your device—from a smartphone to a smart TV.

In this article we will look at all possible scenarios, when the Wi-Fi network is visible and connectable, but the internet isn't working. You'll learn how to quickly diagnose the problem, which settings to check first, and what to do if standard methods don't help. We'll pay special attention to hidden router settings that 90% of users never check, although they often become the source of problems.

1. Checking basic parameters: where to start diagnostics

Before digging into your router settings or calling your ISP, run some simple tests. They won't take more than 2-3 minutes, but they'll help rule out obvious causes.

First, make sure the problem isn't with your internet provider. To do this:

  • 📞 Call your provider's support team (the number is usually listed on your contract or on the router box). Ask if there's any maintenance work going on in your area.
  • 💻 Check if the internet works on other devices. If so, the problem is with that specific device. If not, look for the router or cable.
  • 🔌 Reboot your router: unplug it for 30 seconds, then plug it back in. This solves the problem in 30% of cases.

If after rebooting the router the indicator WAN (or Internet) is off or flashing red/orange—this indicates problems connecting to your provider. In this case:

  1. Check if the cable is firmly inserted into the port. WAN on the router.
  2. If the cable is damaged (the braid is frayed, the connectors are bent), replace it.
  3. Connect the cable directly to the computer (into the port Ethernet). If the internet works, the router is to blame. If not, the problem lies with the ISP.

2. Router settings: what to check first

If basic diagnostics don't help, go to the router control panel. It's usually accessible at 192.168.0.1 or 192.168.1.1 (The exact address is indicated on the device's sticker). The default login and password are often admin/admin or admin/password.

In the control panel, pay attention to the following sections:

Chapter What to check Signs of a problem
Status / State Internet connection status (WAN Connection) Status Disconnected or Authentification Failed
Network / WAN Connection type (PPPoE, Dynamic IP etc.) Invalid type or missing login/password
DHCP Is the DHCP server enabled? Disabled - devices do not receive IP addresses
Wireless Wireless network settings (channel, operating mode) Channel congestion or incompatible mode (802.11ac on older devices)

The most common mistake is Incorrect WAN settingsIf your provider uses PPPoE, check:

  • 🔑 Login and password (they are case sensitive!).
  • 🔄 Authentication type (usually Auto or PAP/CHAP).
  • 🔗 MTU value (default is 1480, but some providers require 1472).

Login to the control panel (192.168.0.1 or 192.168.1.1)

Check WAN connection status

Make sure your PPPoE login/password is correct

Enable DHCP server (if disabled)

Reboot your router after making changes-->

⚠️ Note: If you changed your router firmware or updated it manually, some settings may have been reset to factory defaults. In this case, you will need to completely reset your connection to your ISP.

3. IP Address Issues: DHCP vs. Static Settings

If the router distributes Wi-Fi, but devices do not get access to the Internet, the culprit may be IP address conflict or incorrect DHCP settings. Check on the affected device (PC, smartphone, TV):

On Windows:

  1. Click Win + R, enter cmd, then ipconfig /all.
  2. Look at the line IPv4 addressIf it starts with 169.254.x.x — DHCP is not working.
  3. Check it out Main gateway - it must match the router's IP (192.168.0.1 or similar).

On Android/iOS:

  • Go to Wi-Fi settings, select your network.
  • Look at the IP address. If it 169.254.x.x or 0.0.0.0 — problem with DHCP.
  • Try to manually specify the IP (for example, 192.168.0.100), gateway (192.168.0.1) and DNS (8.8.8.8).

If DHCP does not issue addresses:

  1. Find the section in the router panel DHCP Settings.
  2. Make sure the server is up (Enable DHCP Server).
  3. Check the range of addresses issued (for example, 192.168.0.100 — 192.168.0.199).
  4. If there are a lot of devices, increase the address pool.

4. DNS issues: why websites don't open when the connection is working

Sometimes the Wi-Fi works, the IP address is obtained, but pages in the browser don't load, and instant messaging apps show "no connection." This is a typical symptom. DNS problems — a system that resolves domain names (for example, google.com) into IP addresses.

To check DNS:

  • 🖥️ On PC: In the command line, enter ping 8.8.8.8If pings work but websites don't open, DNS is to blame.
  • 📱 On your phone: install the app PingTools and check the ping before 8.8.8.8.

Solutions:

  1. Change DNS in your router settings:
    • Go to Network → WAN or Internet → DNS.
    • Enter public DNS: 8.8.8.8 (Google) and 1.1.1.1 (Cloudflare).
    • Save the settings and reboot the router.
  • Configure DNS on your device:
    • On Windows: Control Panel → Network → Change adapter settings → IPv4 Properties.
    • On Android: In Wi-Fi settings, tap and hold your network → "Change network" → "Advanced" → DNS.
      • How to check which DNS is faster?

      Use the utility DNS Benchmark (for PC) or application DNS Changer (for Android/iOS). They test the response speed of different DNS servers and select the optimal one. For example, for Russia, DNS servers from Yandex (77.88.8.8) or SkyDNS (193.58.251.251).

      ⚠️ Note: Some providers block third-party DNS services or redirect traffic through their own servers. If your internet connection is completely lost after changing your DNS, reset your settings and contact support.

      5. Channel conflicts and network congestion: why Wi-Fi is slow

      If the Internet appears and then disappears, and the speed jumps from 0 to normal, the problem may be in congested Wi-Fi channel or interference from neighboring networks. This is especially true in apartment buildings, where dozens of routers may operate on a single channel.

      How to check and fix:

      1. Install the application on your smartphone Wi-Fi Analyzer (Android) or NetSpot (iOS) It will show which channels are busy.
      2. In the router settings (Wireless Settings) change the channel to the least loaded one (for example, with 6 on 11 for 2.4 GHz).
      3. If the router supports 5 GHz, try connecting to this network - it is less busy.
      4. Disable the feature Auto Channel Selection - it often chooses suboptimal channels.

    Additional settings for stability:

    • 📶 Set a fixed channel width (20 MHz for 2.4 GHz, 40 MHz for 5 GHz) instead Auto.
    • 🔄 Turn on WMM (Wi-Fi Multimedia) for traffic prioritization.
    • 🚫 Turn it off 802.11b in the wireless settings - this is an outdated standard that slows down the network.

    6. Firewall, antivirus and parental control: software blocking

    Sometimes the internet doesn't work because software limitations on the device. This could be:

    • 🛡️ Windows or macOS firewall blocking the connection.
    • 🦠 Antivirus (especially Kaspersky, Avast, ESET), which "cuts" traffic.
    • 👨‍👩‍👧‍👦 Parental controls on your router or device.
    • 🔒 VPN services that don't connect or conflict with the network.

      • How to check:

      1. Temporarily disable your firewall and antivirus. If the internet works again, look for exception settings.
      2. Check the section in your router Parental Control or Access ControlYour device may be blacklisted.
      3. If you use a VPN, try turning it off or changing the server.
      4. On Windows run in command line: 
        netsh advfirewall reset

        This will reset your firewall settings to factory defaults.

      Pay special attention QoS settings (Quality of Service) in your router. If it has speed limits or priorities for certain devices, this may block internet access for other devices.

      ⚠️ Please note: Some providers (eg. Rostelecom or Beeline) install their own "cloud" antivirus software at the network level. They can block access to certain websites or services. Check this in your provider's personal account.

      7. Hardware problems: when it's time to take your router in for repair

      If none of the methods helped, the problem might be hardware router or network devices. Signs of malfunction:

      • 🔥 The router gets very hot (especially if it smells like burning).
      • 🔌 The indicators light up unstably or do not light up at all.
      • 📡 Wi-Fi drops out when you put your hand near the router (a sign of poor antenna connection).
      • 🔄 After rebooting, the router freezes and does not distribute the network.

      What to do:

      1. Check your router's power supply. If it's bulging or crackling, replace it.
      2. Open the router case (if it is not under warranty) and check if the antennas or capacitors have fallen off.
      3. Connect the router to a different power source (for example, from USB via an adapter).
      4. If your router is older than 5 years, consider buying a new one. Modern models (TP-Link Archer AX21, Keenetic Hero) cope better with the load.

      If the problem is with the computer's network card or the smartphone's Wi-Fi module:

      • 💻 On PC: Check if the network card is detected in Device ManagerIf there's a yellow triangle next to it, update your driver.
      • 📱 On your phone: turn it on Airplane mode for 30 seconds, then turn it off. If that doesn't help, reset your network settings.

      FAQ: Frequently asked questions about Wi-Fi without internet

      Why does Wi-Fi work on my phone but not on my computer?

      This is a typical situation when the network settings on your PC are corrupted. Check:

      1. Disable VPN or proxy in Windows settings.
      2. Reset the TCP/IP stack: From the command line, run: 
        netsh int ip reset

        netsh winsock reset

      3. Update your network card driver via device Manager.

      If that doesn't help, try connecting your PC to the router via cable. If the internet works, the problem is with your computer's Wi-Fi module.

      What should I do if my router doesn't assign an IP address ('No network access' error)?

      Reasons and solutions:

      • 🔌 DHCP is disabled in the router: go to settings and turn it on DHCP Server.
      • 📵 Connection limit reached: check in the router Maximum DHCP Users and increase the value.
      • 🔄 IP conflict: Manually set the IP address on the device from the router range (for example, 192.168.0.100).
      • 🛠️ Firmware failure: reset the router to factory settings using the button Reset.
      Is it possible to use the Internet via Wi-Fi if the provider has disabled access?

      No, if your provider has blocked your account for non-payment or another reason. In this case, Wi-Fi will still be available, but traffic won't go beyond the router. Check:

      1. Personal account balance in the provider's personal account.
      2. Connection status in the router panel (should be Connected, and not Authentification Failed).
      3. SMS or email from the provider notifying about blocking.

      If the block is confirmed, pay the debt or contact support to find out the reason.

      Why did my Wi-Fi connection disappear after I changed my password?

      Changing your password should not affect your internet access, but sometimes:

      • 🔑 You accidentally changed not only your Wi-Fi password, but also your settings WAN (for example, login/password for PPPoE).
      • 🔄 The router froze when applying new settings. A reboot will help.
      • 📡 "Guest mode" with limited access has been enabled. Check your settings. Guest Network.

      Reset your old password and see if your internet connection is restored. If so, the problem lies with the new security settings.

      How do I know if my ISP is blocking certain websites?

      There are several ways:

      1. Try opening the blocked website through Tor Browser or VPN. If it opens, it's blocked by your provider.
      2. In the command line, run: 
        tracert ya.ru

        If the trace terminates at the provider's IP address, the site is blocked.

      3. Check the list of blocked resources in your provider's personal account (section "Parental Control" or "Security").

      If the blocking is confirmed, please contact support or use alternative DNS (for example, 1.1.1.1 to bypass some restrictions).
