Error 012

Samsung Smart TV

Severity: Minor

What Does This Error Mean?

Error 012 means your Samsung TV cannot connect because of a wireless network channel conflict. The TV and your router are having trouble agreeing on a Wi-Fi channel to communicate on. Changing your router's Wi-Fi channel or switching to a different frequency band usually fixes this.

Affected Models

  • Samsung QLED Q80B
  • Samsung Crystal UHD AU8000
  • Samsung Frame TV
  • Samsung Neo QLED QN85B
  • Samsung Lifestyle TV The Serif

Common Causes

  • Your router is using a Wi-Fi channel that is congested with interference from neighboring networks
  • The router is set to a specific channel that your TV's wireless adapter does not support
  • The router is using a 5 GHz channel that is too far from the TV for a stable signal
  • Channel auto-selection on the router has chosen an unstable or overlapping channel
  • Cordless phones, microwaves, or baby monitors are causing interference on the current channel

How to Fix It

  1. Log in to your router's admin panel (typically at 192.168.1.1 or 192.168.0.1 in a browser).

    You'll find the username and password printed on a sticker on the back of your router.

  2. Navigate to the Wi-Fi or Wireless settings and change the channel to a less congested option such as channel 1, 6, or 11 on 2.4 GHz.

    Channels 1, 6, and 11 do not overlap with each other, making them the best choices on 2.4 GHz.

  3. If available, switch the TV to connect to the 5 GHz band instead of 2.4 GHz by selecting the 5 GHz network on the TV.

    5 GHz has more available channels and less interference, though it works best when the TV is close to the router.

  4. Set your router's channel selection to 'Auto' so it picks the best channel at startup.

    Auto mode helps when the interference source changes over time — the router re-evaluates on each reboot.

  5. Restart the router after changing channel settings, then reconnect the TV via Settings > General > Network.

    The TV needs to re-establish the connection fresh after any router channel change.

  6. Move cordless phone bases, microwaves, and baby monitors away from the router and TV if possible.

    These devices emit signals on the 2.4 GHz frequency and can interfere with Wi-Fi channels.

When to Call a Professional

Contact your internet service provider if you cannot access your router's admin panel to change channels. Samsung Support can confirm whether your TV model supports specific Wi-Fi channels or bands. A network specialist can perform a Wi-Fi site survey to find the least congested channel in your home.

Frequently Asked Questions

What is a Wi-Fi channel conflict and why does it cause Samsung TV Error 012?

Wi-Fi channels are like lanes on a road — multiple networks using the same channel cause traffic jams. When too many routers in your area use the same channel, signals interfere and connections drop. Changing to a less crowded channel gives your TV a clear path to communicate with the router.

Should I use 2.4 GHz or 5 GHz for my Samsung TV?

5 GHz is faster and less congested, making it ideal for streaming on a Samsung TV. 2.4 GHz travels farther through walls and is better if the TV is far from the router. If your TV is within 20 feet of the router, always prefer 5 GHz for the best performance.

How do I know which Wi-Fi channel my neighbors are using?

Free apps like Wi-Fi Analyzer (Android) show all networks nearby and their channels. Look for the channel with the fewest competing networks and switch your router to that one. On a computer, you can also see nearby networks in Windows Network settings.
