A Blu-ray is an optical disc storage medium that is an improvement upon the DVD format. Blu-ray disks have 25 gigabytes of storage per layer, and are available in single- or dual-layer. Connecting a Sony Blu-ray player to the Internet can be very easy if you use a wired connection, but wireless makes it a little more difficult, depending on the exact player you have--most just require a wireless adaptor.
Turn on the Blu-ray player and go to the "Setup" icon using the arrow keys on the remote.
Navigate to "Network Settings" using the remote and then press "Enter." Select "Internet Settings" and press "Enter" again.
Hit the "Enter" button to select to start configuring your Blu-ray player.
Select "Wireless" and press "Enter" on the remote. Select "Access point scan" and then continue. Now the player will search for networks.
Select the network that matches your network's SSID and press "Enter." The player will automatically detect the correct encryption type, so just hit "Enter" again.
Press "Enter" on the remote to begin entering your passphrase. Use the remote buttons to input your phrase and then hit "Enter" again.
Select "Auto Acquisition" to automatically acquire the IP address and the DNS address. When prompted to use a proxy server, select "Do not use." Select to perform a test and when it is finished, your network will be working.
