Sony TV Can't Detect Wi-Fi: Complete Guide to Restoring the Connection

You turned on Sony BraviaAre you trying to connect to a wireless network, but your TV stubbornly refuses to detect any access points—or only detects neighboring networks, not yours? This problem occurs even on new models, and there can be dozens of causes, from a simple router configuration error to hardware issues with the Wi-Fi module. In 80% of cases, the solution takes no more than 10 minutes if you know where to look.

In this article we will look at all possible reasons, according to which Sony KD-55X85J, X90K or another model has stopped detecting Wi-Fi, from simple (like disabled SSID broadcast) to complex (problems with firmware or hardware). You will receive step-by-step instructions With TV menu screenshots, a Wi-Fi compatibility chart, and a router diagnostic checklist. And if the problem goes deeper, you'll learn how to fix it without a service center.

Let's start with the most obvious: checking whether the TV is at fault or whether the problem is with the router. This will save you an hour.

1. Checking the router: why the TV can't see your network

Before you dig into the settings Sony, make sure the problem isn't with your signal sources. Here are three key points that are often overlooked:

• 🔄 The router is not broadcasting the SSID.Many users hide their network name for security reasons (the "Hide SSID" option). TVs Sony They can't connect to hidden networks automatically—you'll have to enter the name manually.
• 📶 Incompatible Wi-Fi standardIf your router only works in wireless mode 802.11ac (5 GHz), and the TV only supports 802.11n (2.4 GHz), they simply "don't see" each other. This is true for older models. Bravia 2015–2017.
• 🔌 DHCP is disabled. Televisions Sony By default, they obtain an IP address automatically. If the DHCP server is disabled in the router, connection will be impossible without manual configuration.

How to quickly check:

1. Take your smartphone or laptop and check if it can see your network. If not, the problem is definitely with the router.
2. If the network is visible but the TV won't connect, try connecting another device (tablet, second phone) to it. This will help rule out authorization issues.
3. Take a look at your router's web interface (usually at 192.168.1.1 or 192.168.0.1) and check:
   • Is SSID broadcasting enabled (Wi-Fi or Wireless tab)?
   • What network standard is selected (must be 802.11b/g/n for 2.4 GHz or 802.11a/n/ac for 5 GHz).
   • Is DHCP enabled (section "LAN" or "Local Network")?

Attention! If your router is dual-band (2.4 + 5 GHz), try disable 5 GHz during the test. Many TVs Sony (especially budget series) do not support this range or operate inconsistently in it. After connecting to 2.4 GHz, you can re-enable 5 GHz for other devices.

2. TV settings: where to look for the error

If the router is ok, but Sony Bravia The Wi-Fi still isn't working. The problem lies in the TV's settings. Let's start with some basic checks:

• 🔍 Airplane mode. Yes, on TVs Sony There's also this feature! It disables all wireless modules, including Wi-Fi. Check the menu. Settings → Network → Airplane Mode.
• 🔄 Reset network settingsSometimes it's enough to reset just the network settings without affecting other settings. Path: Settings → Network → Additional settings → Reset network settings.
• 📡 Firmware updateOutdated software can cause connection issues with modern routers. Update your TV via USB or Ethernet (if available).

More information about firmware updates:

1. Go to Settings → Support → Software Update.
2. If the TV does not find updates via Wi-Fi, download the firmware from official Sony website (Please specify the exact model, for example, KD-43X80J).
3. Copy the file to a flash drive (in the root directory, without folders), insert it into the TV's USB port and follow the on-screen instructions.

Disconnect your TV from the Internet (if connected via cable) | Download the firmware for your model from the official website | Format the flash drive to FAT32 | Do not turn off the TV during the update (the process takes 5-15 minutes) -->

Critical information! If the TV Sony If your router, manufactured in 2018 or later, doesn't recognize networks with WPA3 encryption, try switching it to WPA2-PSK. Many models don't support the new security standard.

3. Diagnosing hardware problems

If neither resetting the settings nor updating the firmware helped, the problem may be in hardwareHere are the signs that indicate this:

• ❌ The TV doesn't see it not a single one Wi-Fi network, even neighboring ones.
• ⚡ The Wi-Fi indicator on the TV (if available) is not lit or is flashing red.
• 🔌 Ethernet connection works, but Wi-Fi connection doesn't.

What you can do yourself:

1. Check your Wi-Fi antennaIn some models Sony Bravia (For example, X950HThe Wi-Fi antenna is connected separately to the motherboard. If the connection is broken, there will be no signal. To access the antenna, you need to remove the back cover (do this only when the power is off!).
2. Test with external adapterIf your TV has a USB port, you can try connecting it. Wi-Fi adapter (For example, TP-Link TL-WN725N). Not all models Sony support this function, but on Android TV (For example, X800H) it will work.
3. Checking the power supplyUnstable voltage can cause problems with the Wi-Fi module. If the TV periodically turns off or malfunctions, the problem may be with the power supply.

Attention! If you're unsure of your disassembly skills, it's best to take your device to a service center. Damage to cables or the board during DIY repairs can lead to complete loss of warranty (if it's still valid).

How to test a Wi-Fi module without disassembling it?

If your TV can't see the internet, but you have a smartphone that supports OTG, you can try connecting your phone as a USB modem (via a USB cable). If the internet works via your phone, the problem is definitely with the TV's Wi-Fi module.

4. Wi-Fi compatibility issues

One of the most common reasons why Sony Bravia doesn't see the network, - incompatibility of standards between the TV and the router. For example:

• 📡 The TV only supports 2.4 GHz, and the router is configured to 5 GHz.
• 🔒 The router uses WPA3, and the TV only works with WPA2.
• 📶 Mode enabled 802.11r (Fast Roaming), which is not supported by many models Sony.
