Whatever computer you're running mHotspot on, you'll have to have one connection coming in and one coming out. I personally could not get mHotspot working, so I used Connectify instead. It is really simple. You choose the internet connection you want to share, and the device you're going to use to send the signal out, and it just works. I have internet coming in via my laptop's internal wireless, and I plugged in another USB wireless device and I use that to share the internet with the Wii.I have the game and everything installed right now, I got Overplay and mhotspot, I'm really not good at this sort of thing though, and am having trouble setting it up. I've read a few guides posted on here, but I'm still not sure how bridging the connection works.
I have VPN connection for Japan setup, but how do I connect to that using the Wii's WiFi? If I'm on that connection, does it mean I'm not on my normal internet connection? I'm a total noob at this, any help would be appreciated.
