It’s not a question of security, it’s a question of quality.
It seems that if you are getting your internet access from your cable provider and have to take that wired connection, make a wireless connection and feed it back to your TV wirelessly, there can be issues of quality.
Ah, I thought you were more concerned from a security or intrusion stand point.
There is no doubt that there is a quality issue of wired vs wireless, but when watching Neflix or old YT music vids, it is negligible (of course it depends completely on the content source quality).
I also have a wired connection to the surround amp/receiver so I can play stored (high quality) music through the system and yes, I can detect a difference vs wireless, but playing a DVD on the laptop and putting it through wirelessly, well same thing. But you really have to have a critical ear and eye to detect the difference.
But for being able to put anything that is on the computer through the system, for me this works really great.
TY for your reply!
