"Who's the last one to turn on Wi-Fi?": solving the connection problem on A4 TVs

Phrase "Who will be the last to turn on Wi-Fi?" became a meme among TV owners AOC A4, Hisense A4 And TCL A4 — but behind the jokes lies a real problem. Users often encounter the TV freezing and displaying an error during the final network setup process. WIFI_CONNECT_FAILED Or it simply returns to the menu without connecting. What's the reason? It's not the "last step" per se, but rather the firmware and network settings specific to these models.

In this article we will look at Step-by-step Wi-Fi connection algorithm on TV series A4, we will find out why the process is interrupted at the final stage, and give concrete solutions for various scenarios—from resetting settings to manually entering DNS. We'll also explain why some routers (for example, TP-Link Archer C6 or Keenetic Lite) conflict with TV and how to fix it.

⚠️ Attention: If your TV is released 2018–2021, check the firmware version in the menu Settings → About TV. On older versions (below 4.2.2) there may be no support for modern standards Wi-Fi 6 or WPA3 - this is a common cause of failures.

1. Why doesn't the A4 TV make it to the final connection step?

The main complaint from users is: "It gets to the last item, 'Connect to Wi-Fi,' spins the loading screen, and returns to the menu."There are several reasons, and they depend on the TV and router model:

• 🔄 Conflict of safety standards: A4 TVs often don't support WPA3 (only WPA2-PSK). If the router is configured for mixed mode WPA2/WPA3, TV may “freeze” at the authentication stage.
• 📶 Weak signal on channel 13+: Wi-Fi channels up to 13, but some TVs (especially Hisense A4) don't work well on higher channels 11.
• ⏳ DHCP Timeout: If the router takes a long time to assign an IP address (more than 30 seconds), the TV will terminate the connection with an error. IP_CONFIG_FAILED.
• 🔌 Energy saving: On some models (eg, AOC A4 43") in the menu Eco mode background activity of the Wi-Fi module is disabled.

🔍 How to identify your problem? Go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and check:

• 🔒 Security type (must be WPA2-PSK).
• 📊 Wi-Fi channel (try to install 6 or 11).
• ⚡ Signal strength (if less 50%, move the TV closer to the router).

2. Step-by-step instructions: how to connect Wi-Fi to your A4 TV

Follow this algorithm to minimize the risk of failure at the last step:

1. Turn on your TV and go to the settings menu: click Menu on the remote control → Settings → Net → Wi-Fi.
2. Select your network: If it is not in the list, click Refresh or Search for networks.
3. Enter password: use virtual keyboard on the screen. If the password is long, connect a USB keyboard to the TV.
4. Click "Connect": This is where freezing often occurs. If nothing happens after 30 seconds, move on to section with solutions.

⚠️ Attention: On TVs TCL A4 After entering the password, a window may appear asking you to select the connection type: Personal or Enterprise. Choose Personal, even if you have a corporate router - otherwise, the TV will request additional certificates.

Check that the router is turned on and distributing Wi-Fi|Make sure the password is entered correctly (case-sensitive!)|Disable the VPN on the router (if any)|Restart the TV before connecting-->

3. Error codes and their decoding

If the connection is interrupted, the TV may display one of these codes:

A critical feature of the 2020 Hisense A4 TVs: they do not support IPv6 DNS servers. If your router assigns IPv6 addresses, disable this feature in its settings.

4. Manual connection: if the automatic method does not work

If your TV stubbornly refuses to connect automatically, try setting up the network manually:

1. In the Wi-Fi menu, select Add a network manually.
2. Enter:
   • 📡 Network Name (SSID): the exact name of your Wi-Fi (case sensitive!).
   • 🔐 Security type: WPA2-PSK (If you are not sure, check in your router).
   • 🔑 Password: Please type slowly - the TV's virtual keyboard may "swallow" characters.
   • 🌐 IP address: If the router does not issue it automatically, specify it manually (for example, 192.168.0.100).

For DNS, please specify 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

💡 Helpful tip: If the internet works after connecting manually, but YouTube or Netflix don't load, check your settings. MTU in the router. For A4 TVs, the optimal value is 1472.

5. Problems with specific router models

Some routers conflict with A4 TVs due to firmware issues. Here are the most common combinations and solutions:

• 🔴 TP-Link Archer C6/C7: Disable the feature Fast Roaming (802.11r) in the Wi-Fi settings. It prevents older devices from connecting.
• 🟡 Keenetic (any models): In the Wi-Fi menu, set Compatibility mode and turn it off "Client filtering".
• 🟢 ASUS RT-: Check that in Wireless Network Settings included Legacy Mode (support for older devices).
• 🔵 Xiaomi Mi Router: Update your router firmware—older versions have a bug with WPA2 authentication for TV.

⚠️ Attention: If you have dual-band router (2.4GHz + 5GHz), A4 TVs usually only work with the network 2.4 GHz. Try:

1. Disable the 5 GHz network in your router settings.
2. Or give the networks different names (eg. MyWiFi_2.4 And MyWiFi_5).

What should I do if my TV connects but the speed is slow?

If Wi-Fi is connected, but the video is slow or the quality is lower 1080pThe problem may be in your router's QoS settings. Go to its control panel and:

1. Find the "QoS" or "Traffic Prioritization" section.

2. Add the MAC address of the TV (you will find it in TV Settings → About TV → Network Information) to the list of priority devices.

3. Set the minimum guaranteed speed to at least 10 Mbps.

If there is no QoS, try switching the Wi-Fi channel to a less busy one (use the app Wi-Fi Analyzer for analysis).

6. Resetting settings and alternative connection methods

If nothing helps, try hard reset your TV (all data will be deleted!):

1. Disconnect the TV from the network.
2. Press and hold the button Menu on the remote control + button Volume Down on the TV body (usually on the side).
3. Hold for 10-15 seconds until the recovery menu appears.
4. Select Factory Reset (may be called Factory Reset).

🔌 Alternative ways to connect to the Internet:

• 📡 USB Wi-Fi adapter: Some A4 TVs support external adapters (eg. TP-Link TL-WN725N). Connect it to the USB port on the TV.
• 🔌 Cable connection (LAN): If your router is nearby, use an Ethernet cable—it's the most stable option.
• 📱 Mobile hotspot: Create a hotspot on your smartphone and connect your TV to it. This will help you determine whether the problem is with the TV or the router.

⚠️ Attention: After the reset, the TV may request a firmware update. Do not interrupt the update process - this may brick your device (break the software). If the update is stuck, unplug your TV for 1 minute and then try again.

7. Frequently asked questions and myths about Wi-Fi connection on A4

🔍 Myth 1: “You need to click ‘Connect’ exactly 5 times and it will work.”

❌ Reality: The number of attempts doesn't affect the result. If the TV doesn't connect, the problem is in the settings, not in "number magic."

🔍 Myth 2: “A4 TVs do not work with Rostelecom routers.”

❌ Reality: The problem isn't with the provider, but with the router settings. Rostelecom often ships devices with this enabled. WPA3 default - it needs to be converted to WPA2.

🔍 Myth 3: “If you enable Guest mode on the router, the TV will connect.”

⚠️ Reality: Guest mode can help, but only if client isolation is disabled in it (AP Isolation). Otherwise, the TV will not see other devices on the network (for example, a DLNA server).

FAQ: Answers to frequently asked questions

My A4 TV doesn't detect Wi-Fi at all. What should I do?

Check:

1. Is the Wi-Fi module enabled in the TV settings (Settings → Network → Network Mode).
2. Is Wi-Fi turned off by the hardware button on the case (available on some models)? Hisense).
3. Is Wi-Fi working on other devices (phone, laptop?)? If not, the problem is with the router.

If all else fails, your TV's Wi-Fi module may be broken. In this case, only a service center can help.

Wi-Fi stopped working after a firmware update. How do I roll back?

Firmware downgrades on A4 TVs are not officially supported. However, you can try:

1. Download the old firmware version from the manufacturer's website (for example, for AOC A4 — aoc.com).
2. Write it to a flash drive in the following format: FAT32 (the folder should be called upgrade).
3. Insert the flash drive into the TV and go to Settings → Software Update → Local Update.

⚠️ Risk: Incorrect rollback can damage your TV. If you're unsure, contact a service center.

Is it possible to connect the A4 TV to Wi-Fi without a remote control?

Yes, there are several ways:

• 📱 Use remote control app from the manufacturer (for example, Hisense RemoteNow or AOC TV Remote).
• 🖱️ Connect USB keyboard or mouse to TV - some models support control through them.
• 🔌 If your TV has buttons on the body, use them to navigate the menu (usually Volume And Channel work like arrows).

The TV connects, but YouTube doesn't work. What's wrong?

The problem may be:

• 🌍 Geoblocking: If your router uses a VPN or proxy, YouTube may block content. Disable the VPN in your router settings.
• 🔄 Provider restrictions: Some operators (eg. Beeline) limit traffic for video services. Check your plan.
• 📅 Legacy application: Update YouTube via App Store on TV or reinstall it.

How do I find the MAC address of my A4 TV to connect it to a router?

The MAC address can be found:

1. In the TV menu: Settings → About TV → Network Information.
2. On the sticker on the back of the TV (look for the line MAC Address or Wi-Fi MAC).
3. In the router settings: go to the section DHCP clients or Connected devices - there will be a list of MAC addresses.
