My Samsung usb wireless LAN adapter is not being detected by the tv. Does anybody know how to resolve this issue? Thanks

The adapter did work for sometime - correct?

Any power outages or other electrical disruptions?

Have you checked the TV's settings to verify that the adapter is still the "input" source?

Are the wireless settings for the adapter correct?

Does the adapter work on any other televisions? Does the TV work with other "inputs"?

Do you get any screen messages on the TV?

Is the adapter showing up as a network device on the network?
