The situation when Android TV or Google TV Sony's TV displays a connected wireless network icon, but apps refuse to download content. This is one of the most common smart TV issues. The user sees a message about connecting to an access point, but no data is actually transferred, making it impossible to watch streaming services or update the system.
This problem often occurs due to a conflict in the router's security settings, incorrect DNS addresses, or a temporary failure in the module. Wi-Fi The TV itself. Unlike a complete loss of signal, when the device simply can't see the network, the problem here lies deeper—in the logical interaction between the router and the client device. Understanding how the Sony TV communicates with the router will help you quickly find the root of the problem.
Next we will look at the specific technical reasons why IP address can be obtained, but the default gateway cannot, and what steps need to be taken to restore full access to the global network.
IP address conflicts and DHCP server failures
The first and most common reason for the lack of internet access when there is a connection is the incorrect operation of the protocol DHCPWhen a Sony TV requests a network address, the router must provide it with unique parameters. If there is already a device with the same address on the local network, IP address or the address pool is exhausted, the TV will receive a physical connection but will not be able to send data packets to the outside world.
Often, the problem is resolved by simply rebooting the router, which clears the address lease table. However, in complex cases where there are many smart devices on the network, static assignments may conflict with dynamic ones. A TV may "remember" an old address that the router has already reassigned to another device, creating a collision.
⚠️ Important: If you manually entered a static IP address in your TV settings, make sure it is in the correct range for your subnet and isn't already in use by another device. A single digit in the gateway will completely block your network connection.
To resolve the address conflict, we recommend forcibly updating the DHCP license. This can be done in the TV interface by resetting the network settings. You can also reserve an address for your MAC address. Sony Bravia in the router settings to prevent this situation from happening again in the future.

Problems with the provider's DNS servers
The second most common reason why a Sony TV may remain stuck in the "Connected" status without actual access is broken DNS servers. The Domain Name System (DNS) is responsible for converting domain names (like youtube.com) into machine-readable URLs. IP-If your ISP provides DNS services that respond slowly or don't respond at all, your browser and TV apps won't be able to find content servers.
A common symptom of this issue is that some apps work (if they use their own DNS or IP addresses), while others don't. Or YouTube launches, but the video doesn't load. In the operating system Android TV, which modern Sony models are based on, the network stack may incorrectly handle DNS timeouts, showing a false "Internet is available" status.
The solution is to manually register alternative DNS addresses, such as those from Google or Cloudflare. This often immediately restores access to online services.
To change the settings, go to the menu Settings → Network & InternetSelect your network, click "Edit" or "Advanced Settings," and switch the IP mode from "Auto" to "Static" (or just find the DNS field). Enter your preferred DNS 1, for example 8.8.8.8, and alternative DNS 2, for example 8.8.4.4.
MAC address filtering and router restrictions
Many users forget that strict security restrictions can be set at the router level. Function MAC filtering Allows you to restrict network access to a specific list of devices. If your Sony TV is connected to Wi-Fi (knows the password), but its physical address isn't whitelisted by the router, the connection will be established, but traffic will be blocked.
It's also worth checking whether the "Guest Network" mode is enabled, which prevents access to local resources or limits session time. Some routers automatically disable older or rarely used devices to conserve resources, which can cause the TV to perceive the network as being disconnected.
| Type of restriction | Symptom on Sony TV | Where to check in the router |
|---|---|---|
| MAC filtering | There is a signal, but no data transmission | Wireless / MAC Filter |
| Parental control | Blocking specific applications | Parental Control / Access Control |
| Client Isolation (AP Isolation) | Invisibility of other devices on the network | Advanced Wireless Settings |
| Time limit | The Internet disappears after a specified period of time | Access Schedule / Time Control |
| Port blocking | Only web surfing works | Firewall / Port Forwarding |
To diagnose the issue, you need to log into the router's web interface (usually at 192.168.0.1 or 192.168.1.1) and check the security sections. Make sure that your TV's MAC address (you can find it in Settings → About TV → Network) is not blacklisted.
How to find the MAC address on a Sony TV?
Press the HOME button on the remote. Go to Settings (gear icon). Select "Network & Internet." Click the name of your Wi-Fi network or select "View network settings." The physical address will be listed as the Wi-Fi MAC address in the format XX:XX:XX:XX:XX:XX.
Dual-band routers and frequency conflicts
Modern routers operate in two bands: 2.4 GHz and 5 GHz. They often share the same network name (SSID), and the router automatically decides which frequency to connect to. Sony TVs, especially older models or budget series, may not switch between bands correctly or become stuck on the congested 2.4 GHz channel, where speeds drop to zero, even though the connection is technically established.
The problem is aggravated if the router uses a standard 802.11ax (Wi-Fi 6), and the TV only supports 802.11ac or nIn an attempt to optimize the connection, the router may assign the TV parameters that its Wi-Fi module cannot reliably support, resulting in a "connected but no internet" state.
It's recommended to separate networks on the router by giving them different names (e.g., Home_2G and Home_5G) and connect the TV to the 5 GHz network if it's within line of sight of the router. This will ensure higher throughput for 4K content.
If separating networks is not possible, try forcing a compatibility mode for the wireless network in the router settings, for example, mixed mode 802.11 b/g/n, disabling experimental features like TWT (Target Wake Time), which may not work correctly with TV.
System time and security certificate failures
One of the most subtle reasons why apps don't work when connected to Wi-Fi is a misaligned date and time on your TV. Security protocols SSL/TLSServices used to encrypt traffic (YouTube, Netflix, and the browser) require the server's time to match precisely. If the TV's date is set to, say, 2015, the security certificates are invalidated, and the connection is blocked.
This often occurs after the TV has been disconnected from the power supply for a long time or after a firmware failure. In this case, the TV may show a connection to the router, but no app will be able to establish a secure connection to the server.
Check the time settings in the menu Settings → Date and TimeMake sure "Use network time" (automatic sync) is selected. If the time isn't updating, try temporarily disabling Wi-Fi, setting the time manually, and then re-enabling the network to sync.
⚠️ Note: Android TV and Google TV operating system interfaces may vary depending on the software version and region. If you can't find the exact menu name, look for sections related to "System," "Device Preferences," or "General Settings."
Wi-Fi module hardware malfunctions
If software solutions don't help, physical degradation of the Wi-Fi module inside the TV cannot be ruled out. With prolonged use and heat, components can fail or become unstable. A symptom is that the TV sees the network, attempts to connect, and obtains an IP address, but the data transfer rate is zero or the connection constantly drops.
In such cases, a full power cycle can help, which is different from a regular remote control shutdown. It's necessary to completely de-energize the device to discharge the capacitors and reset the power controller cache.
Follow these steps: turn on your TV, then press and hold the power button on the remote (or on the TV) for 5-10 seconds until the reboot menu appears. Select "Reboot." If this doesn't help, unplug the power cord for 2-3 minutes.
Frequently Asked Questions (FAQ)
Why do other devices work but Sony TV doesn't?
This indicates a specific configuration issue with this particular device. The TV may have "remembered" incorrect network settings, have an IP address conflict, or its MAC address may be blocked by the router. An outdated version of the TV's firmware that doesn't support the router's new encryption standards may also be the cause.
How do I reset network settings on a Sony TV?
Go to Settings → Network & Internet → Network Reset (or "Forget Network"). After that, remove your Wi-Fi network from the list of saved networks and reconnect, entering the password. As a last resort, a factory reset via the "Storage & Reset" menu may help.
Can an antivirus on a router block a TV?
Yes, if your router has parental controls or traffic filtering features enabled (such as blocking ads or certain categories of websites), they may mistakenly classify smart TV traffic as suspicious and block its access.
What should I do if my TV sees the 5 GHz network but doesn't connect?
Make sure the 5 GHz Wi-Fi channel is selected from the allowed list (in Russia, for example, not all channels are allowed). Try setting the channel width in your router settings to 20 or 40 MHz instead of 80/160 MHz for better compatibility.
