I dont know if this is the proper place for this problem, but it seems like a good place to find a solution so here goes nothing: I have many computers in my house that wirelessly connect to my WRT54G. The WRT54G is configured to filter MAC addresses and use WPA encryption, because one of the computers was having problems using WEP. The problem I am about to have is the Nintendo DS doesn't support WPA encryption. I had thought that I could just temporarily disable the encryption when I wanted to use my DS online, but I tested that with one of my computers and doing so broke the connection. It was looking for a WPA encrypted router as the "right" one and couldn't find it. I dont want to have to reconfigure most of my computers every time I start and stop using my DS online. Does anyone know a way I can get around this problem? I dont really know how wireless security works, but it seems like there could be something I could do to the router to make it say "oh, that's the DS, I'm not supposed to encrypt things when I talk to the DS". Or maybe there is a way for it to run in encrypted mode AND unencrypted mode, so that the connection to the computers won't be broken? Thanks for your help!
