Wired Equivalent Privacy (WEP)
Yes, it is. WEP is one form of security for a wireless network, the key is required to decrypt it.

'WEP' is a form of wireless encryption. Your PS3 is asking for the same passcode that you use on your PC or laptop, to connect to your wireless network.
That doesn't technically make sense - a WEP key is the password used to access an encrypted (one form of encryption at least) router. If you don't have a router, it makes no sense to ask for a WEP key - a WEP key to access what? It's like a key with no lock, the WEP key is for a router.So if there's no router, there's no point wanting a WEP key. If there is a router and you don't know the WEP key, then clearly it's someone else's router, and the encryption is precisely to stop unauthorised people using it.
WEP stands for Wired Equivalent Privacy - it is a form of wireless encryption which stops unauthorised people accessing a router or encrypted data. On the PSP, the WEP key is the decryption key for a specific router - so you'd use the same WEP key your PC or laptop uses to connect to your wireless router, then the PSP can use it too.
WEP has been replaced by WPA.
Where is the WEP key?
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.
WEP, or Wired Equivalent Privacy, is a kind of wireless encryption. So if your wireless router is using WEP encryption, it will have a passcode to allow your devices to connect and use it. That is what the DS is asking for.
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.
