Was the unit purchased and being used in the United States?
Have you performed firmware update, either using USB thumb drive or by using the network update? Since I don't have much information here to troubleshoot with, I might recommend contacting the Samsung customer service center at 800-SAMSUNG for troubleshooting assistance.
Just purchased a Samsung Blu-Ray Disc Player, BD-C5500. I cannot get past the Internet@TV page which appears to just be a dead link. The Network Status shows everything to be connected and signal strength is reported as excellent. There is a message on the Internet@TV page (superimposed over the middle of the page) which says: "Connect to the Internet and enjoy variety of contecnts through Internet@TV." This, to me, is an indication it isn't connected, and I have no clue how to proceed.
Any suggestions would be greatly appreciated!
