Im currently using a USB to Ethernet adapter connected from my non-wireless linksys router to my Wii. The connection is fantastic and fast and this adapter works first time without having to install any software or codecs or run a cd or anything, just plug and set up the connetion in the wii settings. Heres the newegg product link, its only around $20.00 usually, or it was when i purchased it, and its usually in stock. KINAMAX USB 2.0 A-Male to A-Male 3ft Extension Cable Model USB-AMAM - Retail This works, there are videos on YouTube of it working, and there is another Wii message board on which dozens of users including myself have confirmed it working. Im posting this because i noticed it wasnt stickied and it should be and i saw an earlier post about people wondering if there was something that worked in the USB port. Well here ya go, if this is already stickied in another board i apologize but i figured whats the harm. If i find that video ill post it.
