Ok so here's the deal. Today I tried to connect my DS on wifi (or whatever it's called) so I can play online, but after introducing my correct WEP key it said that it couldn't connect. The configurations on my router had WEP-Open, so I changed them to WEP-Shared and I could play. But then I realized that the wireless connection that my dad was using on his computer stopped (i think on his PDA too). To solve this I returned from WEP-Shared to WEP-Open and he had the connection again, but then I can't play online with my DS. Is there a way to solve this? Or do I have to switch between this two, each time I want to play on my DS-and-when my dad needs the connection? Help
