Samsung TV Error Code 202: How to Fix It
Error 202 means your Samsung TV joined your Wi-Fi but couldn't reach the internet or Samsung's servers — a network or DNS issue often shown as 'ISP blocking service', not a broken TV.
Quick answer
Error 202 is a connection fault between your Samsung TV and the internet/Samsung servers — despite the 'ISP blocking service' wording it's usually DNS. A full power cycle plus a network reset often fixes it.
- 1.Unplug the TV for 60 seconds (hold the power button 30s while unplugged), then plug it back in.
- 2.Go to Settings → General (or Connection) → Network → Reset Network, then reconnect to Wi-Fi.
What it means
Error 202 appears when your Samsung TV managed to join your home network but could not finish the handshake with the internet or Samsung's servers — it often shows the misleading message 'ISP blocking service' or 'unable to connect to network'.
Despite that wording your provider is rarely blocking anything: the fault is almost always DNS or a temporary router/Samsung outage, so the fix is about refreshing the connection, not repairing the panel.
Common causes
- Router or modem lost internet. The most common cause: your router or modem dropped its internet connection or simply needs a restart, so the TV can join Wi-Fi but has no path to the internet.
- ISP DNS can't resolve Samsung's servers. Your provider's DNS fails to look up Samsung's server addresses, so the TV is on Wi-Fi yet still can't connect — this is exactly what triggers the 'ISP blocking service' message.
- Weak or unstable Wi-Fi signal. The TV is too far from the router or the signal keeps dropping, so the connection to the internet never completes.
- Outdated TV firmware. An old Tizen build can mishandle the network handshake and surface the failure as 202.
- Temporary ISP or Samsung-side outage. Your provider's network or a Samsung/app service is briefly down, and the TV reports the failure as error 202.
Before you start
- Test another device (phone, laptop) on the same Wi-Fi — if it also has no internet, the problem is your router or ISP, not the TV.
- Check whether Samsung's servers or the affected app are reporting an outage in your region.
- Note if the error started right after a firmware/app update or after your ISP had a service problem.
Fixes, from safest to last resort
Power cycle the TV
No data loss- 1Unplug the TV from the wall (not just the remote power-off).
- 2With it unplugged, press and hold the TV's power button for 30 seconds to drain residual power.
- 3Wait a full 60 seconds, plug it back in, turn it on and try again.
This clears the TV's temporary memory and re-initialises the network stack — it often resolves 202 on its own.
Restart your router and modem
No data loss- 1Unplug the power cord from both the router and the modem (if separate).
- 2Wait 60 seconds so they fully reset and re-establish the internet link.
- 3Plug the modem in first, wait for its lights to stabilise, then the router, and retry on the TV.
Because 202 usually means the TV has Wi-Fi but no internet, refreshing the modem/router is where the connection is most often restored.
Reset the TV's network settings
Re-setup needed- 1Open Settings → General (or Connection) → Network → Reset Network.
- 2Confirm with Yes.
- 3Reconnect to your Wi-Fi and enter the password again.
This clears saved Wi-Fi and network settings but does NOT remove your installed apps or accounts.
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 (Google DNS), save and retry.
This is the key fix for the 'ISP blocking service' variant of 202: it bypasses your provider's DNS when that DNS can't resolve Samsung's servers. 8.8.4.4 works as a secondary.
8.8.8.8Update the TV firmware
Re-setup needed- 1Go to Settings → Support → Software Update → Update Now.
- 2If Wi-Fi won't connect, download the firmware from Samsung's site to a USB drive and update from USB.
- 3After updating, restart the TV and retry.
Factory reset (last resort)
Removes apps & settings- 1Only if every step above failed and other devices on the same Wi-Fi do have internet.
- 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 everything else — especially the DNS change — first.
If a menu doesn't match your TV
- If you don't see 'Reset Network', look under Settings → General → Network on older Tizen models, or Settings → Connection → Network on newer ones.
- The same fault can appear as 'Error code 202', 'ISP blocking service' or 'unable to connect to network' depending on the model and year — the fixes are identical.
When to contact support
Contact Samsung support if error 202 persists after a firmware update and factory reset, or if other devices have internet but the TV still fails on every network:
- Have your model number ready (Settings → Support → About This TV).
- Mention which steps you already tried, especially the network reset and the DNS change to 8.8.8.8.
- Ask them to check for a known service-side or regional issue affecting your TV.

Frequently asked questions
Does 'ISP blocking service' mean my provider blocked Samsung?+
Almost never. The message is misleading — in practice error 202 is a DNS or network problem. The TV can be on Wi-Fi yet fail to reach Samsung's servers, and switching DNS to 8.8.8.8 usually fixes it.
Will resetting the network delete my apps?+
No. Reset Network only clears saved Wi-Fi and network configuration. Your installed apps and logins stay. A full factory reset is the only step that removes them.
Why does changing DNS to 8.8.8.8 help with error 202?+
If your internet provider's DNS can't resolve Samsung's servers, the TV connects to Wi-Fi but still can't reach the internet. Google's public DNS (8.8.8.8) bypasses your ISP's DNS and completes the lookup.
