Works perfectly as I already have OpenWRT on my router, thanks. 
 
It seems quite a few people must be doing this as I got hits from all over the world.
 
I suspect they will have to update the 3DS firmware to bypass this at some point though as I'm sure if too many people do it then it will mess up the StreetPass relay function at the hotspots we are spoofing.
They're not going to bother with it as it does no harm, if anything it generates sales of the new streetpass games.
Besides, if they really wanted it to be imune to spoofs they'd just need to change the router software.
Been using it for a week or two now, tried on my phone, my laptop, computer, a few routers, and finally got it working on my dd-wrt one what I had to unbrick, despite it being in a box and was working fine before I put it away.
