DSi cant connect to internet...ARHH!

OK...so i just got a DSi & followed the steps. I have a wireless router(d-link) & a nintendo wi-fi USB connector plugged in to my PC..i get a message saying error code 052003-1

I am stumped.
i went to the support site & it said to try up-dating rouuter firmware...but havent been able to do that yet...(dont ask)

you have seen this? here they give some other solutions than up-dating firmware.

so i followed these steps & am STILL getting the message..

Unable to connect to access point....

OK...so made some progress today..adjusted the settings on my router.it still didnt work..took a time out.

son came home from school..took him 15 minutes to figure it out!

I was happy & mad..happy it works & mad that he let me get so frustrated for a friggin week!~~~
