How do I fix Netflix error NW-4-8 on a Samsung TV?
Answer
NW-4-8 usually means the TV cannot reach Netflix over the network. Restart the TV and router, confirm other apps online, then reinstall Netflix if the error remains.

- Do not enter your Netflix password on any site linked from a popup claiming to fix NW-4-8.
Follow these steps
Power-cycle the TV
Turn the Samsung off, unplug it for about one minute, plug it back in, and reopen Netflix.

Restart the modem and router
Unplug the modem/router for one minute, restore power, wait until other devices are online, then retry Netflix on the TV.
You should see: The TV still shows an internet connection and Netflix is retested.
Check TV network and other apps
