Sony TV Won't Connect to Wi-Fi: Causes and How to Fix It

You are trying to connect a TV. Sony Bravia to your home network, but it stubbornly doesn't detect Wi-Fi, displays an authentication error, or simply freezes during the connection process? This problem occurs on newer models (X90K, A95L), and on the old ones (KD-55X8500C 2017). In 80% of cases, problems with the router or incorrect TV settings are to blame—and only 20% are due to hardware issues.

In this article we will look at all possible reasons, from the banal (incorrect password) to the rare (5 GHz channel conflict), and we will also give step-by-step instructions with illustrations from real menus SonyWe will pay special attention to models with Android TV And Google TV - their connection algorithm differs from the classic ones Bravia On Linux. If your TV doesn't work with Wi-Fi after a firmware update or a reset, you'll find a solution here too.

Before proceeding to diagnostics, answer one question:

1. Basic checks: router, password, and network mode

Start with the obvious - often the problem lies not in the TV, but in the environment. Here 4 key pointsthat need to be checked to how to dig into the settings Sony:

• 🔌 The router is turned on and distributing Wi-Fi.Make sure the wireless network indicator is lit (usually green or blue). If it's blinking orange, reboot the router using the button. Reset on the back panel.
• 📶 TV in coverage area. Sony Bravia TVs with weak Wi-Fi (especially pre-2019 models) may not have a network connection through two or three walls. Move the TV closer to the router or check the signal on your phone in the same location.
• 🔑 Correct passwordEnter it manually (not using autofill!), taking into account case and special characters. On some routers, the password is displayed in the web interface at 192.168.1.1 (logins admin/admin or see the sticker on the router).
• 📡 Network operating mode. Televisions Sony older than 2018 may not be supported Wi-Fi 6 (802.11ax)Switch the router to the mode 802.11n/ac (settings → Wireless → Mode).

If all of the above is ok, but Sony Still not connecting, please proceed to the next section. Problems arise especially often when using dual-band routers (2.4 + 5 GHz), where the TV gets stuck on the frequency selection.

2. Wi-Fi settings on your TV: step-by-step instructions

Even if you've connected your TV to the network a thousand times, it's worth going through the settings again—sometimes the settings get reset after an update or a power surge. This guide is relevant for Android TV/Google TV (models 2015–2026) and classic Bravia on Linux.

Open the settings menu:

HOME button on the remote → ⚙️ Settings → Network → Network setup → Wi-Fi setup

Next, select your network from the list. If it's not there:

• 🔍 Click Refresh the list (button F5 or Sync on the remote controls Sony).
• 📡 Try adding the network manually via Add a network manually (please provide your name) SSID and type of security WPA2-PSK).
• 🔄 If the TV freezes at the IP acquisition stage, switch the router to the mode DHCP (not a static IP).

After entering the password, an error may appear. Failed to connect to the networkIn this case:

1. Restart your TV (press and hold the power button for 10 seconds).
2. Disable it in the router menu MAC address filtering (if enabled).
3. Try connecting to a 2.4 GHz network instead of 5 GHz (or vice versa).

3. Channel and frequency conflicts: why Sony can't see the network

One of the most insidious reasons is Wi-Fi channel incompatibility. Televisions Sony (especially US/European models) may not support channels 12–14 in the 2.4 GHz range or channels DF 5 GHz. If the router is set to this channel, the TV simply won't see the network.

How to check and fix:

1. Go to the router's web interface (192.168.1.1 or 192.168.0.1).
2. Find the section Wireless Settings → Channel.
3. For 2.4 GHz, select the channel 1–11 (optimal 6 or 9).
4. For 5 GHz, select a channel 36–48 or 149–165 (avoid DF).
5. Save the settings and reboot the router.

If after changing the channel the TV still does not connect, try narrow the channel width to 20 MHz (for 2.4 GHz). This will reduce speed but improve stability. The setting is in the same section. Channel Width.

Why are there different channels in Europe and the USA?

Different countries have different regulatory restrictions on the use of Wi-Fi channels. For example, channels 12–14 are prohibited in the US, while in Europe they are permitted but may interfere with radar (DFS). Sony For the American market, European channels are often “not seen”, and vice versa.

4. Firmware issues and resetting settings

Software glitches are the second most common cause of Wi-Fi problems. If your TV Sony It used to connect to the network, but after the update it stopped. The firmware is to blame. Here's what to do:

• 🔄 Reset network settingsGo to . Settings → Network → Reset network settingsThis will delete all saved passwords, but often solves the problem.
• 📥 Update firmware manuallyDownload the latest version from the website. Sony (support section for your model), save it to a flash drive in the format FAT32 and update via Settings → Support → Software Update.
• ⚠️ Roll back the firmwareIf the problem appeared after an update, try reverting to the older version (instructions below).

For manual update:

1. Download the firmware for your model (for example, KD55X85J_PKG7.5620.0001NAA.zip).
2. Unzip the archive and copy the file .pkg to a flash drive.
3. Insert the flash drive into the USB port of the TV (usually USB1).
4. Run the update via Settings → Support → Software Update → Update from USB.

⚠️ Warning: Interrupting the firmware update process may result in complete inoperability of the TVIf the screen goes blank or freezes during the installation process, do not turn off the power — Wait 30–40 minutes. If the TV doesn't turn on after the update, contact a service center.

If the problem occurred after an automatic update, try rolling back to the previous version. To do this:

1. Download the old firmware from the forums (for example, AVS Forum or 4PDA).
2. Rename the file to sonydtv.upg.
3. Download it through the same section Software update.

5. Features of Android TV and Google TV

Televisions Sony on Android TV (2015–2020 models) and Google TV (2021–2026) have additional Wi-Fi issues due to Google services integration. If your TV freezes during the connection check or displays an error IP configuration not received, try:

• 📱 Disable Google syncGo to . Settings → Accounts and sign-in → Google → Remove account.
• 🔧 Reset Android network settings. In the developer menu (Settings → About TV → Build number - press 7 times) select Reset Wi-Fi, mobile network, and Bluetooth.
• 🛡️ Disable VPN or proxySome applications (eg. NordVPN) conflict with the system network settings.

If the TV connects to Wi-Fi, but the internet is not working (pages don't load, applications give errors), check:

• Settings DNS (try specifying it manually 8.8.8.8 And 8.8.4.4).
• Firewall or parental controls on the router (may block access) Sony to Google servers).
• The date and time on the TV (if they are out of order, SSL certificates will not work).

On Google TV (models X90J, A80J and newer) additionally check:

Settings → Network & Internet → Wi-Fi → Advanced → Private DNS

If it's there automatic or a custom address, send it to off.

6. Hardware faults: how to diagnose

If all software methods have been tried, but Sony still not connecting to Wi-Fi, possible hardware failureHere are the typical symptoms:

• 📵 The TV doesn't see it not a single one network, although other devices (phone, laptop) connect normally.
• 🔌 The Wi-Fi indicator on the TV is not lit or is flashing red.
• 🔥 After a thunderstorm or power surge, both Wi-Fi and Ethernet stopped working.
• 🛠️ In the service menu (call via i+ → 5 → 10 → 20) an error is displayed WLAN: NG.

The most common hardware reasons:

1. Wi-Fi module failure (often after overheating or moisture). On models Sony this is a separate fee Wi-Fi/Bluetooth, which can be replaced.
2. Antenna problems (cable break or contact oxidation). This applies to TVs with an external antenna (e.g., KD-65X9000F).
