If you still can't connect because it can't acquire youre dhcp do the following. Found the solution In a wifi game you need to go to the settings and enter the settings manually for your connection. so you need to enter the wifi settings for your connection and select no for auto-obtain ip address. Now to find this info if using XP click start > run and type in cmd /k ipconfig /all and press enter. You will need to enter the IP Address of the DS - this will be the same as the IP address shown by doing the above but change the last number to anything between 0 and 99, i used 5 so my ip entered is - xxx.xxx.x.5 the subnet mask is under the ip address in the command window Gateway is under the subnet mask Then the Primary and Secondary DNS should be just below. Now to run Beup or any other wifi app you need to start a wifi game. For example mario kart, connect to the ds wifi and then reset your DS. RESET, do not turn it of or it wil not work. I have a supercard so i press the button combination. Now run BEUP or any other wifi program. It should connect. I only have one so I entered the same for both and it worked fine. I've noticed that resetting Mario Kart DS with the supercard software can corrupt the upper screen. (No it's not broken.) I mean that it could not show the upper screen correctly with beup or win2ds or some apps. You need to connect with tetris ds and then softreset, then the screen would stay normal. Try this!! It works for me.
