Downloaded and installed WLAN driver
from Samsung site.
Downloaded and installed Easy Settings 18.104.22.168
When I open Easy Settings, I can select Boot Management, General, Power Management, Display and Desktop Background / Screen Saver with no problem.
However, when I select "Wireless Network", I get: "Easy Settings has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
But Windows does not close the program or notify me -- it continues to search for something in an endless loop.
Also, when I select Fn+F12, there is no indication on the screen of any change. Should a Wireless LAN ON message appear?
I will leave my WiFi connection shortly, but may be able to check later for additional advise / suggestions via a dial-up connection (please don't say anything :-), but hope to return to a WiFi connection tomorrow to continue the effort to identify and fix this problem.
