So in using this thread people have made it possible to use many different devices to create your own at home streetpass relay. This is exciting news but I have been constantly running into issues as I try to do this myself and have come to you guys for help.

I am trying to do the OSX setup on my macbook and I just can't seem to change my Mac Address. I have followed the instructions exactly, numerous times the past 2 hours and can't seem to get it to change. I'm not sure what I'm doing wrong but also when I start to share my wifi, it looses the IP address it had when it was connected to my network and just stops working. Just a huge mess and this stuff is way over my head but wondering if anyone has an idea of what to do to get this working.

@nightriff I've been using my Windows 7 desktop PC and the MAC Cycler found here to great effect for a few days now. I had to try a few times to get it to work initially though. I don't know much about OSX but from your post, are you using two different connections, like a wired and wireless? The wireless connection that connects to the 3ds shouldn't be in use or connected to anything.
