My best diagnostic is to take my laptop to that Sony and unplug the ethernet and try it on my laptop. My bet is the laptop can't use that ethernet connection. Why is not in the clues provided so I'll share my testing method.
Hello, inexperienced person here, but wanting to learn and thankful for this forum!
Ok, what I am trying to do is help a friend. Because I have done a little web design for him he has come to me with a networking problem. However, I know little to nil about networking.
-He owns restaurant.
-Wants to run Pandora on outside dining area for patrons through a Blue-Ray to a TV.
-Wants it wired.
-Have not been there yet to (try to) troubleshoot myself. But I have a feeling I'll end up here anyway.
-The POS (machine they take orders on) (Windows XP OS) connects to 2wire modem/router provided by DSL company.
-Then runs to what he says is a Netgear ethernet switch through drop ceiling.
-Then runs to the Sony Blue-Ray, connected to TV.
-Says it detects the connection but no internet.
-What could be the most common cause that I might try. Says Network diagnostics function on Blue-Ray menu does say make sure DHCP is enabled.
