Problems with WiFi connection

Well, i am trying to connect to my router using WiFi by DS. It says that the connection was succesful but when i click to connect to the wifi menu of the game (where you can duel etc.) the router restarts and then a message in my ds states that the connection was not accomplished

I have tried :
To connnect my phone AND my laptop to my internet connection via WiFi and worked FINE !
To install/unistall drivers for USB Connector (still nothing happened)

Note: There was no problem about.. a month ago o.O

Anyone that has to suggest anything ?

It's been days so... BUMP !

Haven't seen this thread actually. Try reading this then.

I read your topic but i have already done the WEP configurations. I cant understand why my router restarts when I try to connect.

Oh? So it restarts? Try turning on the DMZ hosting or toning down the security to allow the DS to get access.

Yeah but the problem is that i don't know how to apply the changes you mentioned in my router :/ Im using Siemens SL2-141 hope this helps.

Sorry for bumping again. Can you give me a link to the nintendo support forums ?
