Aren't most BD players today wireless? Why don't you want to go wireless? Then you could connect many devices like if you got another BD player or an iPad or tablet or laptop. Or if you got a game system or a Roku box, etc. Or if visitors bring over a laptop, etc.
Wireless is the way to go.
I have Charter internet, which runs through the cable line. I have two wired devices, on opposite sides of my house, that I want to connect to the internet: My computer, and a blu-ray dvd player. I THOUGHT I could just buy a second modem and hook it up to the coax cable on the other end of my house -- if I had cable tv it would work in the whole house but NO, charter insists that their internet service is ONE wired modem per house and that, to connect my second modem, I'd have to pay for internet AGAIN, doubling what I already pay. NO WAY. They offered me a "free wireless upgrade". NOT what I need. Told me I could buy a repeater. As far as I've seen those are WIRELESS ONLY.
What else can I do that doesn't involve stringing a 200 ft ethernet cord from one end of my house to the other?
