WEP has been replaced by WPA.
Where is the WEP key?
Wired Equivalent Privacy (WEP)
Probably 578511 is an error indication but i know that a wep key has to have letters in it so 578511 is not a wep key.
The WEP key is found on the router, not the DS unit or the WII. The WEP is different all routers.
The 64 bit WEP key uses a 40 bit (10 Hex character) Encryption and a128 bit WEP key uses a 104 bit (26 Hex Character) Encryption.So the 128 bit WEP key is a higher level of encryption compared to 64 bit WEP.
A wep key has nothing to do with Pokémon Pearl, it is your wireless router's password.
The WEP key is unique to the installation. There is no master key.
A WEP key is get up off lazy butt and find it out your self
No. The WEP key is a separate password.
Yes you can set up a WEP on any router, but WEP is not very secure.WPA and WPA 2 would be a better way to go.
Check your wireless router's documentation on how to find its WEP key. Assumedly your PC/laptop also connect to your router, so they should have the WEP key already or else they couldn't connect.
