Thank you

for making this post and confirming that this router is compatible with Nintendo WFC.
As of this posting, the ver 4001 model is not listed on nintendowifi.com.
I saw this router for about $40 at Wal-Mart this morning,
but wasn't sure if i should buy it. I will now.
I happen to have a d link router that is not compatible with Nintendo WFC.
Also, I have issues getting a computer that is like 3 rooms away and downstairs to work consistently with my dlink router.. hopefully the belkin will have better range.. we'll see!
Btw.. this post is the first listing that comes up when searching:
f5d7230-4 ver 4001 "nintendo ds"
on google.
