Is there any way to connect to the internet with a Sony BDP-BX37 WITHOUT paying $80 for this:

Like a different type of LAN adapter or wireless card that doesn't cost as much? I tried using a WI-FI card I had bought years ago for my Wii that worked on my Wii and my laptop great, but the player says it doesn't recognize it.
