Samsung TV Error Code 102 appears when your TV is unable to connect to the internet, typically caused by a DNS (Domain Name System) configuration problem. This means your TV can reach your router but cannot properly resolve web addresses to load apps or streaming services. The good news is that this is almost always a software or network settings issue that you can fix at home without any special tools.

When to Call a Professional

You should contact Samsung Support or a certified technician if Error Code 102 persists after completing all steps above, especially if wired and wireless connections both fail, if the TV's network diagnostic shows a hardware-level failure, or if the TV's Wi-Fi adapter appears to be physically damaged or non-functional. You can reach Samsung Support at 1-800-726-7864 or via Samsung's online support chat. If your TV is still under warranty, do not attempt any internal hardware repairs, as doing so may void coverage.

Frequently Asked Questions

What does Samsung TV Error Code 102 mean?
Samsung TV Error Code 102 means your TV has a network connectivity problem, specifically a DNS (Domain Name System) failure. Your TV can detect your router but cannot translate website addresses into the IP addresses needed to reach Samsung's servers and streaming services. Setting a manual DNS like Google's (8.8.8.8) typically resolves it.
How do I fix Error Code 102 on my Samsung Smart TV?
The fastest fix for Samsung TV Error Code 102 is to manually set your DNS server. Go to Settings > General > Network > Network Status > IP Settings, switch DNS to 'Enter Manually,' and type 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS). Save and test your connection. If that does not work, restart your router and TV, or reset the TV's network settings.
Why does my Samsung TV keep showing Error Code 102 even after restarting?
If restarting does not clear Error Code 102, your router's DNS settings may be misconfigured, your ISP may be experiencing DNS issues, or there may be a corrupted network profile on your TV. Manually entering a public DNS address like 8.8.8.8 bypasses your ISP's DNS servers and almost always resolves persistent cases of this error.
Is Samsung TV Error Code 102 a hardware problem?
In almost all cases, Error Code 102 is a software or network configuration issue, not a hardware problem. It is caused by DNS settings, router issues, or outdated firmware — not a broken part. Only in very rare situations, such as when the TV's internal Wi-Fi adapter has failed, would hardware be to blame. If a wired Ethernet connection works but Wi-Fi does not, the Wi-Fi hardware may need service.
Will a factory reset fix Samsung TV Error Code 102?
A factory reset can fix Error Code 102 if the cause is deeply corrupted network settings or firmware that cannot be repaired any other way. However, it should be your last resort because it erases all your settings, apps, and preferences. Try manually setting the DNS to 8.8.8.8, resetting your router, and updating the TV firmware before resorting to a factory reset.
