This situation is familiar to many owners. Smart TV from Samsung, LG, Sony and other brands. The problem lies not with the TV itself, but with the network settings, router, or even the ISP.

In this article we will look at all possible reasons, which the TV can see Wi-Fi, but does not have access to the Internet, and we will offer step-by-step instructions for each of them. You'll learn how to check your router, change DNS settings, update your TV firmware, and even manually configure your network if automatic connection doesn't work. We'll pay special attention to hidden router settings that block access for "unknown" devices - This reason occurs in 30% of cases.

Don't rush to reset your TV to factory settings or call support—in 90% of cases, the problem can be resolved independently in 10-15 minutes. Let's start with the simplest and gradually move on to more complex methods.

1. Checking basic parameters: router, cables, other devices

Before digging deep into your TV settings, make sure the problem isn't with your home network. Start with some basic checks:

• 🔌 Reboot your routerUnplug it from the power outlet for 30 seconds, then plug it back in. Wait until it fully boots up (the indicators should be steady).
• 📶 Check the internet on other devicesIf you can't access the internet on your smartphone or laptop, the problem lies with your ISP or router settings.
• 🔗 Inspect the cablesIf you have PPPoE-connection, make sure that the cable from the provider is tightly inserted into the port WAN (usually highlighted in blue).
• 🌐 Log into the router's web interfaceEnter in your browser 192.168.1.1 or 192.168.0.1 (logins/passwords usually admin/admin). Check your internet connection status.

If the internet works on other devices but not on the TV, proceed to the next section. If there's no internet connection on all devices:

⚠️ Attention: The problem may be with your provider. Call support and check if they are currently undergoing maintenance. Some providers (for example, Rostelecom or Beeline) block access to certain services for "unauthorized" devices.

2. DNS settings: why the TV doesn't open websites, but is connected to Wi-Fi

One of the most common reasons is Incorrect DNS settingsThe TV connects to the router but cannot resolve domain names (e.g. youtube.com → IP address). As a result, you see the error "No internet access," even though you have a Wi-Fi connection.

The solution is simple: manually enter public DNS from Google or CloudflareInstructions for most models Smart TV:

1. Open Settings → Network → Network settings (on Samsung the path may differ: Menu → Network → Network Status).
2. Select your Wi-Fi network and click "Advanced settings" or "Change".
3. Find the item DNS and enter:

   8.8.8.8
   8.8.4.4

   (this is DNS from Google) or

   1.1.1.1
   1.0.0.1

   (this is DNS from Cloudflare).

4. Save the settings and restart the TV.

If the internet works after changing the DNS, the problem was with your ISP settings. Some operators (for example, MTS or Third Transport Ring) use their own DNS servers, which can block access for "non-standard" devices.

3. IP addressing issues: conflict or missing address

The TV may not receive an IP address from the router due to:

• 🔄 IP conflict (two devices on the network have the same address).
• 🚫 Disabled DHCP on the router (the TV cannot automatically obtain an IP).
• 🔒 MAC address filtering (the router blocks unknown devices).

How to check and fix:

1. View the current IP of the TV:
   • On Samsung: Settings → Support → Network Status.
   • On LG: Settings → Network → Network Status.
   • On Android TV (For example, Sony or Xiaomi): Settings → Network & Internet → Wi-Fi → [your network] → Advanced.

   If the IP starts with 169.254.x.x - this is a sign that the TV has not received an address from the router.

2. Set up a static IP manually:
   • Enter an IP from your network range (e.g. 192.168.1.100, if the router has an address 192.168.1.1).
   • Subnet mask: 255.255.255.0.
   • Gateway: IP of your router (usually 192.168.1.1 or 192.168.0.1).

Check your router's DHCP settings.:

• Go to the router's web interface (192.168.1.1).
• Find the section LAN or DHCP.
• Make sure the DHCP server is enabled and the address range is not exhausted (for example, with 192.168.1.100 to 192.168.1.199).

⚠️ AttentionIf "MAC Address Filtering" is enabled in your router settings, add your TV's MAC address to the list of allowed devices. Find the MAC address in the TV's network status (usually looks like this) 00:1A:2B:3C:4D:5E).
