The WEP key is unique to the installation. There is no master key.
You configure them when setting up your wireless router. The SSID is the 'name' it broadcasts, and the WEP key is the code a device needs to be able to unencrypt data sent by it. Once you've got the router set up, you can enter the SSID and WEP key into the DS, to allow it to connect to your router.
The SSID is the 'name' of your wireless network. Just enter that name in, the same as how you did it for your PC/laptop, along with the WEP/WPA encryption key that you set.
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.
You may enhance the sercurity to wep, wpa2.. etc.
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.
No. Your WEP key is the password placed on the router you are trying to access.
A wep key has nothing to do with Pokémon Pearl, it is your wireless router's password.
No. The WEP key is a separate password.
well, my friend. Everybody has there own different WEP key
No The WEP key is the key used to encrypt the wireless traffic, so people can't sniff the data and see what your doing. No WEP key, no connect to the network. No router password, and you can't log into the router to modify the WEP key.
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.
