When to Call a Professional

If your TV fails to connect even after a factory reset, connects successfully via Ethernet but the Wi-Fi adapter never detects any networks, or if the Network Status test consistently fails at the IP address or gateway stage despite a healthy router, the TV's internal Wi-Fi module may be faulty. At that point, contact Samsung Support at 1-800-SAMSUNG or take the TV to an authorized Samsung service center. Also contact your Internet Service Provider if other devices on the same network are also experiencing connectivity issues, as the problem may be with your modem, router, or ISP service rather than the TV itself.

Frequently Asked Questions

What does Samsung TV Error Code 105 mean?
Error Code 105 on a Samsung TV means the TV failed to establish a network connection. This can be caused by a weak or dropped Wi-Fi signal, an incorrect network password, router or modem issues, incorrect DNS settings, outdated TV firmware, or a temporary software glitch inside the TV.
Why does my Samsung TV keep showing Error 105 even though my Wi-Fi is working?
Even if other devices connect to Wi-Fi fine, your Samsung TV can still show Error 105 due to incorrect DNS settings, an outdated firmware version that has a known networking bug, a corrupt network profile stored on the TV, or interference on the 2.4 GHz or 5 GHz wireless band your TV is using. Try manually setting DNS to 8.8.8.8, forgetting and rejoining your Wi-Fi network, or updating the TV firmware via USB.
Will a factory reset fix Samsung Error Code 105?
A factory reset will fix Error 105 if the cause is corrupted network settings, a problematic app interfering with networking, or a software configuration issue. However, it will not fix hardware failures like a broken Wi-Fi adapter, nor will it fix external problems like a faulty router or ISP outage. Try all other steps first before resorting to a factory reset.
How do I fix Samsung TV Error 105 without a remote?
Without a remote, you can use the Samsung SmartThings app on your smartphone to navigate TV settings if the TV is at least partially connected. Alternatively, most Samsung TVs have a physical control button or joystick located on the underside or back of the TV that lets you navigate menus. You can also purchase a replacement Samsung universal remote or use the Samsung TV Plus remote feature in the SmartThings app.
Does Samsung Error Code 105 mean my TV is broken?
Not necessarily. Error Code 105 is a network connectivity error and in the vast majority of cases it is caused by a fixable software or configuration issue rather than hardware damage. Only if the error persists after a factory reset and the TV cannot detect any Wi-Fi networks would a hardware fault (such as a failed Wi-Fi module) be suspected.
