Ok, here's a product I've found which's not of Nintendo.
http://www.dlink.com/products/?sec=0&pid=133
Is this basically what's needed? Should it work?
(and by the way, what the hell is "10/100mbit"? What is this 10? Because 10 mega-bits sounds pretty crappy [my internet is slower than 10mb, but in general for USB connections)
There's no way to tell if that will work with the Wii without testing it. It seems like you're trying to save money wherever possible but it's often easier and will cause the least amount of problems if you go with the official products. Most of these answers you're looking for can be found on Google, by the way (like what is 10/100mbit, etc).
