I already have an existing wireless network. How can I connect an additional access point wirelessly to that network so that the new access point can provide a wired connection to other devices on the network?
Background:
My wife's family gave us a Samsung Blu-ray player as a gift. It has Netflix, Pandora, and other services built-in, provided you can establish an internet connection.
It can only accept a standard Cat5 ethernet connection (the BD-P1600 model allows for an optional propietary wireless adapter, but ours is the BD-P1590, so this option is not available).
In lieu of running Cat5 cable all over our home, I'd like to be able to set up a wireless access point to connect to our existing wireless network and then serve as a hub for wired connections. Can a standard consumer router (such as the Linksys WRT54G) be set up for this purpose or do I need a different device?
