I'm hoping that someone else has been down this road... I just got an R4 for my DSL and I want to use Wood Dumper to back up my carts & saves, but of course the DS only supports WEP and my home network is WPA. I was able to use my wife's Mac to set up an open WiFi network using Internet Sharing, but what I really want to do is set up an isolated WiFi network. I could spend $20 and buy a cheap WiFi NAT router, but I was wondering if my Wii (using Linux) could do the same thing. So I'd boot the Wii into Linux and use something like hostapd to put the internal WiFi interface in master mode so it can accept new connections, then use bootpd as a DHCP serever.
