In this case, Wi-Fi ready means that you can purchase Samsung's WIS09ABGN usb wireless adapter (sold separately). It must be plugged in to the BD player. You would normally access the network settings on the player, select wireless, select your network SSID, then enter your wireless network password. You cannot use a different brand of usb wireless adapter.
You can, however, purchase a wifi adapter that will plug in to the ethernet port of your BD player. I use the TRENDnet Wireless N Adapter, which is less than half the price of the Samsung adapter. It is also much more versatile; you can use it on just about any other device with an ethernet port to give it wireless capabilities.
Last year I purchased a Samsun Blu-Ray player HT-D4500. It is wi-fi ready, and I was just wondering what I must do to hook it up to access Netflix, Pandora, etc. Also, does the adapter hook up to the bluray player or the TV?
Thanks in advance.
