Sony - especially when it comes to models X80J, X90K or older series KD-55XF9005Problems connecting to a wireless network can arise due to incorrect router settings or due to a faulty TV software.

In this article we will discuss all possible reasons, by which your TV Sony won't connect to Wi-Fi - from trivial (for example, an incorrectly entered password) to complex (hardware failures of the wireless module). You will receive step-by-step instructions for diagnostics, as well as ways to solve the problem without calling a technician. We'll pay special attention to models with Android TV And Google TV, where the connection algorithm differs from the classic ones Bravia on its own firmware.

Before you start setting things up, check the obvious: is the internet working on other devices (smartphone, laptop)? If so, the problem is definitely with the TV or its interaction with the router. If not, start over. sort out the router.

1. Checking basic Wi-Fi settings on your Sony TV

Let's start with the simplest thing: it's possible that your TV simply isn't seeing your network or can't connect to it due to some minor issue. Here's what to do first:

• 🔍 Make sure Wi-Fi is turned on on your TV.On the remote control Sony press the button HOME, then go to Settings → Network → Network setup → Wireless setupCheck if the Wi-Fi switch is turned on.
• 📶 Check network visibilityYour network should be listed in the list of available networks. If it's not there, the problem may be with your router (see Section 3).
• 🔐 Please enter your password correctly.The "Incorrect Security Key" error means that you have entered the wrong password. Sony Bravia When you enter a password, dots will appear - their number must match the number of characters in your password.
• 🔄 Restart your TVSometimes simply unplugging the device for 30 seconds helps. This will clear temporary Wi-Fi module errors.

If the connection is not established after these steps, proceed to the next step. Please note: on TVs Sony With Android TV 9.0 and later (For example, X950H, A80J) The network settings menu may look different. In this case, the path will be: Settings → Network & Internet → Wi-Fi.

Important! On some models Sony (For example, KD-43XF7005) After an unsuccessful connection, the message "IP address not obtained" may appear. This means the router isn't assigning a network address to the TV. The solution is to manually set a static IP address (more on this below).

2. Connection errors: decoding codes and messages

Televisions Sony Wi-Fi issues generate specific errors. Let's decipher the most common ones:

If appears on the screen error "Error 103" - this means that the TV Sony can't access update servers due to DNS issues. In this case, changing the DNS servers to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

On models with Android TV (For example, X800H) you may see the message "Connection saved, but no internet access." This means the TV is connected to the router, but it's not providing internet access. Check your router's firewall settings or contact your ISP.
