Samsung TV Error Code 102: How to Fix This Network Error
Error 102 is a network connection failure: your Samsung TV could not connect to the wireless network or reach the Smart Hub servers. It's usually fixed on the network side — router, password, Wi-Fi band or DNS — not by repairing the TV.
Quick answer
Error 102 means the TV failed to connect to your wireless network or Smart Hub. Most cases clear after a full power cycle of the TV and router, followed by re-adding the Wi-Fi network on the TV.
- 1.Unplug the TV and the router for 60 seconds, plug the router in first, wait for its lights to stabilize, then plug the TV back in.
- 2.On the TV, go to Settings → General → Network → Open Network Settings and reconnect to your Wi-Fi, typing the password carefully.
What it means
Error 102 appears on Samsung Smart TVs when the TV cannot establish a working connection to the wireless network or cannot reach the Smart Hub service that apps depend on. In short: the TV and the internet are not talking to each other.
Samsung does not publish an official page explaining each numeric code, so the meaning here comes from answers given in Samsung's own support community and from Samsung's official Wi-Fi troubleshooting steps, which are exactly what resolves this code in practice.
Because the failure sits between the TV and your network — or occasionally on Samsung's servers — the fix is about refreshing the connection, not repairing hardware.
Common causes
- Router or DNS hiccup. The most common cause: the router or your provider's DNS temporarily stops handing the TV a working connection and needs a restart.
- Wrong or changed Wi-Fi password. Samsung lists an incorrect password as the most frequent reason a TV fails to join Wi-Fi — especially after a router change.
- Weak signal or wrong Wi-Fi band. The TV is too far from the router, or it's trying a 5 GHz network it can't use. Some 2018 models (NU6xxx, NU71xx, NU72xx, NU73xx) only support 2.4 GHz.
- Outdated TV firmware. An old Tizen build can fail the connection handshake and surface it as error 102.
- Smart Hub service outage. Less common: Samsung's servers have a temporary problem, in which case the error clears on its own.
Before you start
- Test another device (phone, laptop) on the same Wi-Fi. If nothing has internet, the problem is your router or provider, not the TV.
- Run the TV's own diagnosis: Settings → General → Network → Network Status. An X between the TV and the router means a local Wi-Fi problem; an X between the router and the globe means your internet provider.
- Note whether the error started right after a router change, a new Wi-Fi password or a firmware update — that usually points straight at the cause.
Fixes, from safest to last resort
Power cycle the TV
No data loss- 1Unplug the TV from the wall (not just standby with the remote).
- 2With it unplugged, press and hold the TV's power button for 30 seconds to drain residual power.
- 3Wait 60 seconds, plug it back in, turn it on and try connecting again.
This restarts the TV's network stack and clears temporary glitches — it's a good first step.
Restart your network from the wall out
No data loss- 1Unplug the modem, the router and the TV.
- 2Plug the modem back in first and let it fully boot.
- 3Then the router, then the TV — each one only after the previous device has finished starting up.
Samsung recommends powering the chain back on in order, starting from the device closest to where the internet enters your home.
Re-add the Wi-Fi network on the TV
Re-setup needed- 1Go to Settings → General → Network → Open Network Settings.
- 2Select your network, choose to forget/disconnect it if the option appears, then connect again.
- 3Type the password slowly and check every character — a wrong password is the most common reason the connection fails.
Switch to the 2.4 GHz band (or move the router closer)
Re-setup needed- 1If your router broadcasts separate 2.4 GHz and 5 GHz names, connect the TV to the 2.4 GHz one.
- 2If the signal shows only one or two bars, move the router and TV closer together or add a repeater.
- 3Disconnect a few other Wi-Fi devices temporarily if your network is crowded, then retry.
2.4 GHz reaches farther through walls, and some 2018 models (NU6xxx, NU71xx–NU73xx) can't see 5 GHz networks at all.
Set the DNS manually to 8.8.8.8
Re-setup needed- 1Go to Settings → General → Network → Network Status → IP Settings.
- 2Set DNS Setting to Enter manually.
- 3Enter 8.8.8.8, save and retry the connection.
Helps when the TV joins Wi-Fi but still can't reach Smart Hub because your provider's DNS is failing. 8.8.4.4 works as a secondary.
8.8.8.8Reset the TV's network settings
Re-setup needed- 1Open Settings → General (or Connection) → Network → Reset Network.
- 2Confirm with Yes.
- 3Reconnect to your Wi-Fi from scratch and enter the password again.
This clears all saved networks and network configuration but does NOT remove your apps or accounts.
Update the TV firmware
Re-setup needed- 1Go to Settings → Support → Software Update → Update Now.
- 2If the TV has no connection at all, connect it by Ethernet cable temporarily, or download the firmware for your exact model from Samsung's site to a USB drive and update from USB.
- 3Restart the TV after updating and retry Wi-Fi.
A wired test is also a useful diagnosis: if Ethernet works but Wi-Fi never does, the TV's Wi-Fi module may be at fault.
Factory reset (last resort)
Removes apps & settings- 1Only if everything above failed and other devices connect fine to the same network.
- 2Go to Settings → General → Reset and enter your PIN (default 0000).
- 3Set the TV up again and reconnect to Wi-Fi.
⚠ A factory reset erases all apps, logins, picture settings and preferences. Try every other step first — if the cause is on the router or Samsung's side, a reset won't help anyway.
If a menu doesn't match your TV
- Menu names shift slightly by model year: look under Settings → General → Network on most Tizen TVs, or Settings → All Settings → Connection → Network on newer models.
- If you don't see 'Reset Network', your model may only offer 'Open Network Settings' — forgetting and re-adding the network achieves nearly the same refresh.
When to contact support
Contact Samsung support if error 102 survives a firmware update and a factory reset, or if the TV fails on every network (including a phone hotspot) while other devices connect fine:
- Have your model number ready (Settings → Support → About This TV).
- Tell them the Network Status test result and which steps you already tried, especially the network reset and the DNS change.
- If Ethernet works but Wi-Fi never does, mention it — that points to the TV's Wi-Fi module and may need service.

Frequently asked questions
Is error 102 a problem with my TV or with my internet?+
Usually the network. Run Settings → General → Network → Network Status: an X between the TV and router means a local Wi-Fi issue (password, signal, band); an X between the router and the globe means your internet provider. The TV itself is rarely the culprit.
Will resetting the network delete my apps?+
No. Reset Network only clears saved Wi-Fi networks and connection settings. Apps, accounts and picture settings stay. Only a full factory reset removes those.
Why does my phone connect but the TV shows error 102?+
Phones handle weak signals and 5 GHz networks better than many TVs. Try the 2.4 GHz band, move the router closer, and re-enter the password on the TV — some 2018 Samsung models can't connect to 5 GHz at all.
Can error 102 fix itself?+
Yes, when the cause is a temporary Smart Hub or provider outage. If other devices lose internet at the same time, wait a while and retry before changing any settings.
