Samsung TV will not connect to Wi-Fi: check the TV’s network status, confirm the network name and password, cold boot the TV, and restart the router. Reset Network—not the whole TV—only if the saved connection remains corrupted. Check the router's connected-devices list to see whether the TV appears, which shows whether it joined at all.

Exact questions
Common questions about “Samsung TV will not connect to Wi-Fi”
Why won't it connect?+
Signal or password.
Is the band right?+
Try 2.4 GHz.
Which band should the Samsung TV use?+
If the TV is far from the router, the 2.4 GHz band often reaches further. If it is close, 5 GHz is faster. Try whichever gives a stronger signal at the TV.
Should I check the TV's software?+
Yes. Updating the TV firmware, sometimes over a wired connection or a USB update, can fix Wi-Fi faults that survive router restarts.
What if other devices connect but the TV does not?+
Check the router's device list for a limit or filter, and try assigning the TV a fixed address. A network settings reset on the TV can also help.
Should I check the router's security mode?+
Some older TVs struggle with newer security modes. If your router uses a mixed WPA2/WPA3 mode, switching to plain WPA2 for the test can show whether the mode is the problem. Change it back if it makes no difference.
Could the router be blocking the TV?+
Yes. Some routers use device filtering, or limit the number of connected devices. Check the router's connected devices list and any access controls. Add the TV if needed, and consider reserving a fixed address so it reconnects reliably after restarts.
