Misc Can't connect to a Ad-Hoc network?

[Koekje]

Hello all,

Since the signal of my wireless router is crappy as hell, and i'm connected with my pc via a cable, i decided to turn the wireless card in my pc into an ad-hoc. Also i turned on internet sharing on it. Literally it would mean i can connect with my DS to the ad-hoc network like it's a normal wireless network. Too bad i'm only getting halfway.

It can find the network, but it can't connect.

It gives me an errorcode and the message it wasn't able to connect to any networks. The PC also doesn't give any sign that someone connected to the ad-hoc network. I setted it up without a WEP or something on it.

Anyone have an idea how i can setup an ad-hoc network with my wireless card so i can connect throught that instead of the wireless network?
