Hacking DS Lite wireless Internet problem

[alicefred]

Everything was working pretty fine until last night and now whenever I try to connect my DS Lite to wireless Internet, I get an error code: 51300. I am using a 64-bit WEP key with 10 digits. I asked for help on another board, but found nothing. I don't know much about DS Lite, because I got it last month from http://www.dealrocker.com/promotions/buy.com/deals/. Can anyone point me in the right direction and help me to fix this problem?

Thanks in advance.

If you are using 64-bit encryption, the WEP Key must be a 10-character key consisting of numbers or letters A through F. Also, check this page on the nintendo website to see if there are any specific settings you need for your router:
