i have wireless internet protected with a password but everytime i search for my internet i have to type the WEP key i assume this is the password for my internet right? so i type in this password and it gives me this message 'these settings are invalid. confirm the information and try again' could it be my password is too short because when i added a (dot) it tried connecting but i got error code 51300 (proberly wrong password because i have no dot in it)
can someone please help me because i realy want this to work

oh and its only in the settings when i try to play pokemon diamond because it works on DSi itself

update:

well i search the whole internet to fix it but it seems i can't connect unless i have WEP security settings, and i currently have WPA so that kinda sucks... it seems that i can make use of local internet if they have open acces so perhaps gonna try that sometime...
