Connecting a TV TCL Connecting to a wireless network is a problem that Smart TV owners face when first starting up or after a factory reset. Even if your router is working properly and other devices connect without issue, the TV may stubbornly ignore Wi-Fi or display errors like IP address not received or Authentication failedThe reasons lie in both the TV's settings and the router's parameters.
In this article we will look at all current connection methods — from standard password entry to alternative methods like WPS/QSS (if supported by your model TCL). We'll cover typical errors and how to troubleshoot them: why the TV can't detect the network, why the connection keeps dropping, and what to do if Wi-Fi stops working after a firmware update. You'll also find compatibility table models TCL with different Wi-Fi standards (2.4/5 GHz, 802.11ac/ax).
If you have already tried to connect but were unsuccessful, skip the first section and go straight to problem solvingFor owners of new TVs (2023–2026), updated support information has been added. Wi-Fi 6 and setting up dual-band networks.
Preparation: What to check before connecting
Before you try to connect your TV to Wi-Fi, make sure the problem isn't something basic. 40% connection errors are associated with incorrect router settings or physical interference.
Here's what you must do to start of setup:
- 📶 Check your router signal where the TV is located. Use your smartphone or laptop to measure the signal strength (apps like Wi-Fi Analyzer will show the strength in dBm). If the value is lower
-70 dBm, the signal is too weak. - 🔌 Reboot your router and the TV. Unplug both devices for 30 seconds—this will clear the DHCP cache and any temporary errors.
- 🔒 Make sure the password is entered correctly.On TVs TCL The keyboard may work with a delay - enter characters slowly, checking the case (upper/lower case letters).
- 📡 Disable VPN/proxy on your routerSome models TCL (especially with Android TV) conflict with additional network services.
If your router supports double range (2.4 GHz and 5 GHz), try temporarily disabling 5 GHz in your router settings. Many TVs TCL (especially budget series) work more stably at the frequency 2.4 GHz, despite the lower speed. How to do it:
- Go to your router's control panel (usually at
192.168.0.1or192.168.1.1). - Find the section
Wi-Fi→Wireless network settings. - Disable the option
5 GHzor set a separate network name (SSID) for each band.
Method 1: Standard connection via TV menu
This is the most universal method that works on all models. TCL - from the old ones Roku TV until new ones Google TVThis instruction is valid for firmware versions from 2020 to 2026.
Steps to connect:
- Turn on the TV and press the button
Home(orMenu) on the remote control. - Go to
Settings(gear or wrench icon). - Select a section
Net→Wi-Fi(orWireless network). - In the list of available networks, find the name of your router (SSID). If there is no network, press
Refresh the listorSearch for networks. - Select your network and enter the password. For convenience, use the voice-activated remote (if supported).
- Confirm the connection. The status should appear within 10-30 seconds.
Connected.
If an error appears after entering the password Obtaining IP address..., and then the connection drops, the problem may be with the router's DHCP settings. Try manually setting the IP address on the TV:
- On the menu
Network settingsselectAdditionally→IP settings. - Install
Static IPand enter the data:- IP address:
192.168.0.X(where X is a number from 10 to 254, not occupied by other devices). - Subnet mask:
255.255.255.0. - Gateway:
192.168.0.1(or192.168.1.1, depending on the router). - DNS:
8.8.8.8(Google) or1.1.1.1(Cloudflare).
- IP address:
Make sure the router is turned on and distributing Wi-Fi|
Check that the TV is within range of the network|
Reboot the router and TV|
Disable VPN/proxy on your router (if any)|
Enter your password correctly (case sensitive!)-->
Method 2: Connect via WPS/QSS (if supported)
Many models TCL (especially the series C635, P725 and newer) support the technology WPS (Wi-Fi Protected Setup) or its equivalent QSS (On some routers). This allows you to connect to the network without entering a password—just press a button on the router.
How does this work:
- Make sure your router supports WPS. There's usually a button labeled
WPSor the 🔄 icon. - On your TV, go to
Settings → Network → Wi-Fi. - Select an option
WPS(orQSS,Fast connection). - Click the button
WPSon the router for 2 minutes. The status should appear on the TVConnecting.... - Wait for confirmation. If the process takes more than 1 minute, try again.
Important: WPS may not work if WPA3 security is enabled on your router or WPA2 compatibility mode is disabled. In this case, switch to WPA2-PSK in your router settings.
| TCL model | WPS support | 5 GHz support | Wi-Fi standard |
|---|---|---|---|
| TCL 40C635 | Yes | No | 802.11n (2.4 GHz) |
| TCL 55P725 | Yes | Yes | 802.11ac (dual-band) |
| TCL 65C825 (2023) | Yes (QSS) | Yes | 802.11ax (Wi-Fi 6) |
| TCL Roku TV (S Series) | No | Depends on the model | 802.11n/ac |
If your model does not support WPS, or there is no button on the router, use standard method (section above) or Ethernet adapter (if there is a LAN port).
What to do if WPS doesn't work?
1. Make sure that WPS is enabled on your router (in the wireless network settings).
2. Check if your antivirus or firewall is blocking the WPS function on your router.
3. Try connecting within 1–2 meters of the router—sometimes the WPS signal is weaker than the main Wi-Fi signal.
4. If your router is dual-band, temporarily disable 5 GHz—WPS often only works on 2.4 GHz.
Method 3: Connecting via Ethernet (if Wi-Fi doesn't work)
If the wireless connection fails fundamentally (for example, due to a faulty Wi-Fi module in the TV), you can use wired connectionTo do this you will need:
- 🔌 Ethernet cable (twisted pair, category 5e or higher).
- 📡 Free LAN port on the router.
- 📺 Ethernet port on the TV (not available on all models) TCL).
How to connect:
- Connect the TV and the router with a cable.
- On TV, go to
Settings → Network → Wired Network. - Select
DHCP(automatic IP acquisition) or configure IP manually (similar to Wi-Fi). - Confirm the connection. The status should change to
Connected.
If your TV doesn't have an Ethernet port but it does have a USB port, you can use USB-Wi-Fi adapter (For example, TP-Link TL-WN725N). However TCL Officially supports a limited list of adapters - check compatibility on the manufacturer's website before purchasing.
Solving common connection errors
Even after the TV is set up correctly TCL may produce errors. Let's look at the most common problems and their solutions.
Error 1: The TV does not detect the Wi-Fi network
Possible causes and solutions:
- 🔍 Network is hidden (hidden SSID)Enable network visibility in your router settings or enter the SSID manually on your TV.
- 📶 Incompatible Wi-Fi standardIf the router only works in the mode
802.11r/k/v(Enterprise), switch toWPA2-Personal. - 🔄 Channel conflictIn the router control panel, change the Wi-Fi channel to a fixed one (for example, 6 or 11 for 2.4 GHz).
Error 2: "Authentication failed"
This error means the TV can't connect to the network due to an incorrect password or security settings. What to do:
- 🔑 Check your password. Please re-enter it, making sure the case of the characters matches.
- 🔒 Change the encryption type. Set it in the router settings.
WPA2-PSK (AES)- This is the most compatible mode. - 📱 Check MAC address restrictionsIf MAC filtering is enabled on your router, add the TV's MAC address (you can find it in
Settings → About TV).
Error 3: Constant connection drops
If Wi-Fi connects but disconnects intermittently, the problem may be:
- 📡 Router overloadDisconnect unnecessary devices from the network or reboot the router.
- 🔋 Energy savingsIn the TV settings, disable the option.
Wi-Fi energy saving(if any). - 📶 Interference from other networks. Use the app Wi-Fi Analyzerto find a free channel and change it in the router settings.
