TV is connected to Wi-Fi, but there is no internet access: complete troubleshooting instructions

Has your TV successfully connected to Wi-Fi, but your browser won't open pages, apps won't update, and YouTube displays a "No internet connection" error? This problem affects one in five Smart TV users—and the cause can lie in both the router settings and the TV's firmware. Unlike smartphones or laptops, where network diagnostics are intuitive, TVs often hide critical settings behind complex menus.

We'll figure it out 10 proven methods Restore Internet access to your TV, from basic (rebooting the router) to advanced (manual DNS setup). We'll pay special attention to Samsung QLED models 2020-2023, LG OLED with WebOS And Android TV (Sony, Xiaomi, Philips), where the diagnostic algorithms differ. You will also learn how to distinguish TV problem from router malfunctions - this will save hours on useless manipulations.

1. Diagnosing the problem: is the TV or the router to blame?

Before digging into the settings, determine exactly where the problem is occurring. To do this:

• 📱 Check the internet connection on other devices (smartphone, laptop) connected to the same Wi-Fi network. If the internet works, the problem is with the TV. If not, the router or ISP is to blame.
• 🔄 Reboot your router (unplug it from the power outlet for 30 seconds). This resolves temporary DHCP issues in 40% of cases.
• 📡 Make sure your TV is connected to the correct network. Sometimes devices get stuck on "guest" Wi-Fi with limited access (e.g. TP-Link_Guest).

If other devices work but the TV doesn't, proceed to the next section. If the internet connection is lost on all devices, first call your provider (maybe they're doing maintenance) or check your account balance.

⚠️ Attention: On Keenetic routers And ASUS RT After a firmware update, device priorities may reset. TVs are often blacklisted for restrictions—check the section Local Network → Devices.

2. Checking IP and DNS settings on your TV

Incorrect network settings are the number one reason for no internet connection when connected to Wi-Fi. Your TV may have static IP, which conflicts with the router's address pool, or the DNS settings are incorrect.

Instructions for different platforms:

• 📺 Samsung Tizen: Settings → General → Network → Network Status → IP Settings. Select Receive automatically for IP and DNS.
• 📺 LG WebOS: Settings → Network → Wi-Fi connection → Additional settingsDisable the "Use custom DNS" option.
• 📺 Android TV (Sony/Xiaomi): Settings → Network & Internet → Wi-Fi → Settings (gear) → Advanced → IP Settings.

If the Internet still doesn't work after resetting to automatic mode, try manually entering Google's DNS:

8.8.8.8
8.8.4.4

Or Cloudflare:

1.1.1.1
1.0.0.1

Make sure the IP is obtained automatically

Check if there are any fake DNS addresses registered.

Reconnect to Wi-Fi-->

3. Updating TV firmware without the Internet

Outdated firmware can block internet access due to errors in the Wi-Fi module. But how can you update if there's no network? There are three options:

1. Via USB: Download the latest firmware for your model from the official website (for example, for Samsung QN90B — support section). The file must have the extension .exe (for Samsung) or .epk (for LG) Copy it to a flash drive formatted in FAT32, and insert it into the TV's USB port. Next: Settings → Support → Software Update → Update Now.
2. Via Ethernet: Connect your TV to the router with a cable. Even if Wi-Fi isn't working, a wired connection often works.
3. Via mobile hotspot: Share your internet connection from your smartphone (enable tethering) and connect your TV to this network. Update the firmware, then switch back to your home Wi-Fi.

⚠️ Attention: On Sony Bravia TVs 2019-2021 When updating via USB, a folder may be required SONY_DTV on a flash drive. Without it, the system won't see the firmware file.

What should I do if the firmware freezes during an update?

If the update process is stuck at 0% or 100% for more than 20 minutes:

1. Do not pull out the power cord - this may brick the TV.

2. Press and hold the power button on the remote control for 10-15 seconds (until a forced reboot).

3. If the TV does not turn on, you will need a service center to reflash it via JTAG.

4. Resetting the TV's network settings

If the previous methods don't work, perform a full network reset. This will delete all saved networks and passwords, but it often resolves issues with lagging connections.

Instructions for popular brands:

After the reset, reconnect to Wi-Fi. If the TV asks static IP (occurs on corporate networks), check the parameters with your network administrator or provider.

5. Router Problems: MAC Filtering and Restrictions

Sometimes the router blocks the TV based on MAC address or other criteria. Check:

• 🔒 MAC address filtering: Go to your router's control panel (usually 192.168.0.1 or 192.168.1.1) and find the section Wireless → MAC Filter. Make sure that the MAC address of the TV (you can find it in Settings → About TV → Network Status) not blacklisted.
• 📊 Device limitation: On routers TP-Link And MikroTik check the section Parent Control or Access ControlTVs are sometimes categorized as "Guest Devices" with limited access.
• 🔄 Wi-Fi operating mode: If the router is operating in mode 802.11n only or AX only, old TVs (for example, Samsung Series 6 2016) may connect but not receive internet. Switch to mixed mode. 802.11b/g/n/ac.

Also pay attention to Wi-Fi channelIf the router uses channels 12-14 (not allowed in all countries), some TVs block the connection. Switch channels 1-11.

6. Alternative ways to connect to the Internet

If Wi-Fi stubbornly doesn't work, try these workarounds:

• 🔌 Ethernet adapter: For TVs without a built-in LAN port (e.g. LG OLED C1) buy an adapter USB-to-Ethernet (on-chip models are supported ASIX AX88179). Connect the cable from the router directly.
• 📶 Mobile Internet: Buy a 4G router (for example, Huawei E5577) or use your smartphone as a hotspot. This method is suitable for a summer house or a temporary solution.
• 🖥️ DLNA/Miracast: If you only need the Internet to stream videos, connect your TV to your computer via HDMI or through Wi-Fi Direct (on Samsung — Screen Mirroring).

For Android TV (Sony, Philips) There is another life hack: connect the TV to Wi-Fi, then in the network settings select Advanced → Proxy Server and write down the address noneSometimes this bypasses provider restrictions.

7. When should I contact the service center?

If none of the methods helped, the problem might be hardware TV. Contact service if:

• 🔧 The TV does not connect to any Wi-Fi network (including mobile hotspot), although other devices work.
• 🔥 An error appears on the screen The Wi-Fi module is not responding. or Error 102 (on LG).
• 🔄 After updating the firmware, the TV constantly reboots or freezes on the logo.
• 📡 The Wi-Fi section is missing in the network settings (this may indicate damage to the antenna or module).

Average cost to repair a Wi-Fi module:

Important: On TVs Xiaomi Mi TV 4S And Redmi Smart TV After an unsuccessful update, the eMMC memory may burn out. In this case, repairs will cost 70-100% of the cost of a new TV—it's easier to buy a replacement.
