I had some free time this afternoon, so I figured I try and setup a Streetpass Relay (aka Nintendo Zone). Basically, these relays will get you 10 Streetpasses every 8 hours per MAC address. Now, I can finally get a decent amount of Streetpasses to complete some more puzzles!
I set it up with help from this link:
Setting up a StreetPass Relay at home : 3DS
Basically, you need to setup a wifi access point called 'attwifi', and set the wireless MAC to one of the ones on this list:

Unless you want other people using it, make sure you secure the access point. Since I don't care to share my relay with strangers, I've set the wireless security to WPA, and created a password. Then, I just added the connection to my 3DS setup.
