Wifi troubles

Hello folks.

:D

I'm having quite a bit of trouble connecting my DS and Wii to the Nintendo WiFi usb connector, it used to work fine but now it connects but at the last moment EVERYTIME it disconnects and comes up with Error code: 51203.

Usually when an error happens i just reinstalled the Wifi thingo and it works fine. i have now but it won't work!!!

I've done everything I can but i can't get it working again!!!

Please help me!

EDIT: Why is this stickied!

You have to delete the setting in the wii then redo it. Also make sure the firewall isn't interfering.

Same for the DS games using the wifi you have to redo the setup from the end of the system. When you reinstall it into the pc and do it right the systems do not recognize the comp they are trying to connect to.

FYI they just released a new update to the usb connector. Goto nintendo.com look around in the logical manner and download the update then after uninstalling the usb wifi software device then rebooting install the new version.
