a wireless router -------------------------------------------- blu ray player (with an ethernet port?)
if this is the case you can buy a wireless access point (kind of looks like a baby wireless router), with this piece of hardware you would configure it to your network (by plugging it into a pc first) then plugging it into your blu ray player.
It will recieve a wireless signal and be plugged into your blu ray player by ethernet, it would be the same as plugging your player into your main router with a long cable!
hope this helps
