Fix a Samsung TV that will not connect to Wi-Fi
Separate a TV problem from router, internet, password, signal, and saved-network faults before resetting the television.
Direct answer
The shortest reliable path.
Open the TV network status screen and compare it with another device on the same Wi-Fi. Restart the TV and router, then reconnect after confirming the exact network name and password. If other devices work but the TV still fails, run Samsung Device Care where available, install the current TV software, and use Reset Network before considering a full TV reset.

Scope before steps.
Samsung Smart TVs with built-in wired or wireless networking; menu names vary by model year and region.
ISP account activation, captive-portal networks, enterprise Wi-Fi, damaged Wi-Fi hardware, or model-specific service-menu work.
Procedure
Do this in order.
- 01
Read the network status first
Open Connection or General settings, choose Network, and inspect Network Status before changing anything.
- 02
Compare one nearby device
Use a phone beside the TV on the same Wi-Fi. If it also fails, restore the router or internet service first.
- 03
Restart the path in order
Power off the TV, restart the router according to its instructions, wait for internet service to return, then start the TV and reconnect.
- 04
Run diagnostics and update
Run Samsung Device Care when the model provides it, then check Support → Software Update using Ethernet or USB if Wi-Fi remains unavailable.
- 05
Reset only the saved network
Use Connection → Network → Reset Network, then select the correct Wi-Fi and enter its password again.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| Other devices are also offline | Inspect router status and confirm the ISP connection. | The TV is not the first fault to fix. |
| TV sees the network but rejects the password | Forget or reset the network and re-enter the exact password. | Discovery works; the saved credential or security negotiation is failing. |
| Ethernet works but Wi-Fi does not | Update the TV, compare signal near the router, and test the documented Wi-Fi bands. | Internet and TV apps are proven; the wireless branch remains. |
| TV connects but apps still fail | Check internet status, time, service outages, and the affected app. | Wi-Fi association alone does not prove the app service path. |
Stop conditions
Know when not to keep changing things.
- Do not factory-reset the television while the router or ISP is also offline.
- Do not repeatedly enter passwords until the exact Wi-Fi name and keyboard case are confirmed.
- Contact Samsung when Ethernet works and supported Wi-Fi remains unavailable after software and network reset checks.
