Thanks for all the replies. Some of the articles you added were ones that I have viewed also. We've had to put on our thinking hats for this one, but I think this is where we are at.......first of all, we've discovered that the blu-ray player IS NOT wireless. (after LOTS of trying and changing settings) We thought it was and so did the gift-giver. We've talked to a couple techs in our area and also a Geek Squad member. So it comes down to: running a connecting cable from our modem (east side of one room) to the tv area (west side of adjoining room). This would mean drilling/making a hole in the floor to run it down into the basement, across the basement ceiling and back up thru a hole near the tv. This would get the player 'wired' into our wi-fi. Our other choice is to return the gift and get a wireless player. (leaning towards this choice).
I did a lot of reading on-line, tried a number of suggestions, asked some intelligent questions about the blu-ray, our tv, and our wi-fi to people who know about those things. So if nothing else, I feel like I've educated myself a little bit.
Thanks again and Happy New Year wishes to all.
