Getting Started: Is It a Connection Problem or a TV Problem?

Before you rush into changing options, the most sensible thing to do is, if the Smart TV does not connect to WiFi, Check if the fault is in the Internet itself or is exclusive to the televisionTo avoid wasting time, follow these tips beforehand:

  • Check your internet connection with other devicesConnect your phone, laptop, or any other device to the Wi-Fi network to see if it's running smoothly. If you still can't connect or the speed is ridiculously slow, the problem is with your router or your network provider, not the TV.
  • Take a quick test with your mobile data: Share the connection from your mobile phone by creating a Wi-Fi hotspot (Mobile Hotspot or Personal Hotspot). If the TV connects to this new network, it's your router or your home's Wi-Fi coverage.
  • Try restarting your router and TV.: Sometimes a simple restart of both devices is enough to get back online.

Password and Wi-Fi connection errors on Smart TVs

One of the most common reasons why a Smart TV does not connect to WiFi is something as simple as a Incorrect WiFi passwordAfter changing the password or resetting the router, if the TV tries to pair with the old password, it won't be able to access it. Additionally, some models are incompatible with passwords that include special symbols or uncommon characters.

  • Re-enter the password on the TV: Access your TV's network settings and delete the saved network. Then, select your Wi-Fi again and enter the updated password.
  • Avoid passwords with rare characters as much as possibleIf you suspect your TV is having trouble with certain symbols, try changing your Wi-Fi password to one with only letters and numbers.

Useful tip: Change the frequency band if your router offers two (2.4 GHz and 5 GHz). Both usually have the same password, but each has its advantages and disadvantages in terms of speed and range.

Check the signal: distance, obstacles and interference

El physical distancing The gap between the TV and the router is another major cause of interruptions and disconnections, resulting in the situation where the Smart TV won't connect to Wi-Fi. The further the TV is from the router, the more physical obstacles there are (walls, furniture, doors), and the poorer the Wi-Fi signal will reach. Even other appliances such as microwaves or cordless phones can cause strong interference. interferences, especially in the 2,4 GHz band.

  • Move the router closer to the Smart TV: At least for a trial period, place the router nearby to rule out coverage problems.
  • Consider using repeaters, PLCs or Mesh routersIf your home is large, use WiFi repeaters, mesh systems, or PLC devices to improve coverage. PLCs are only recommended if the electrical installation is modern and stable.
  • Change WiFi channels: Go into your router settings and manually select a less congested channel (useful if you live in an apartment with lots of networks nearby).

Don't forget that some modern routers include features like "band steering," which unifies 2,4 and 5 GHz networks under the same name. If you're having trouble, try disabling this option and using each network separately.

Network overload? Home solution

Another common cause that explains why the Smart TV does not connect to WiFi is the router saturation, especially if you use a modest fiber or ADSL rate and have dozens of devices at home (mobile phones, tablets, computers, consoles, home automation, etc.). When several devices consume a lot of bandwidth (downloads, online games, torrents), the TV can run out of "site» on the net.

  • Disconnect other devices that you are not using and try the TV connection again.
  • Configure traffic priority (QoS) on the router to give preference to the Smart TV over other devices.
  • Check if there are any foreign devices connectedUse apps like Fing to scan all the devices using your Wi-Fi. If you detect anything suspicious, change your router's password.

If problems persist, consult your provider to increase your speed or upgrade your router if it's older.

Checking the hardware and wiring

If you have decided on an Ethernet cable connection and the Smart TV still not connecting, the cable may be damaged or the port may have a problem.

  • Test the cable on another device like a laptop or console. If that doesn't work either, the cable is broken and needs to be replaced.
  • Use a cable tester to detect which thread is bad, if you have one at home.
  • Check the network sockets and if you use a switch to split your wired connection, unplug it to see if the problem goes away.
  • Check the router ports, as some may be damaged. Test each one with the TV cable.

If all else fails, the Smart TV network card has broken down and requires technical service.
