How to hook up Blu-Ray to home network

By reg549 @ Nov 01 2008 07:49 pm

I have a Sony 550 blue ray player with an Ethernet port that is to hook up with the internet to download BD material and obtain firmware updates. I have a wireless home network but am not clear what to purchase to have the two communicate via an Ethernet connection (on the back of the Sony)….can anyone tell me what I need to purchase so that I can connect wirelessly to my home network?
