Misc Problem with dl-624

[Otagamo]

All of a sudden my DS stopped to connect via my router (dl-624), i get the 52100 error, i've tried a bunch of different configurations, and nothing worked... The funny thing is that my Wii can connect to the internet, and my pc can too, and i don't use WPA security, i've tried with Shared WEP, Open WEP, no security at all... Changed the TX to 2, tried different channels, i couldn't turn off the routers firewall, but i didn't add any new rules to it, and my DS worked with it before

...

Well, please someone help me before i throw my DS against the wall

Thanks
