I purchase this bluray player about a week ago. The intial set up went smoothly. I was prompted to do a firmware upgrade. Once I did it, the wirless stoped working and I called samsung. They advised me to reset the unit, which I did. That did not help. I am getting ready to send it back to Amazon. I am really dissappointed with Samsung. I cannot believe they roll out these new products without testing them. Their quality control does not exist.
