First, yes I'm a newbie - a rank, ignorant newbie with minimal computer technology intelligence - which is why I looked for help on Toms Hardware.
Second, why yes I read the manual before I posted, but because I'm a newbie and stupid I found it very difficult to understand.
Third, I first contacted Samsung chat, who informed me that the manual was wrong or no longer applicable in some cases, and that NO I couldn't connect wirelessly. Not being confident in their answer, I turned to Tom's.
Fourth, I knew I could connect by cable and use a wireless keyboard because a previous very helpful, patient and polite responder on Tom's had described to me how to do it. But I had not told him about my blu-ray, and had not broached the idea of wireless because of my ignorance.
Fifth, thank you joshyboy82 for your helpful and polite response. Have a great day.
