That depends on the router being used to connect to the internet. Ask whoever maintains your internet connection.
If you have a Belkin you must change the password(WPA key).
WPA key is a password for your wifi connection it's to help you be secure.
The WEP key is the key for your wireless router, it's the same passkey that your PC or laptop uses to get online.
It means the WPA key for your router, the same key your other devices use to connect to it. It is an encryption key that only lets authorised users use that network.
wep and wpa both are encryption standards to make a more secure wifi network, so your xbox needs to have the same wep/wpa code that your router is set to. if you have to choose between wep or wpa, choose wpa if possible because it is virtualy uncrackable and it will save your bacon
Actually, it's closer to a passŵord (methinks), & it's used to connect to the internet via a given router [the wi-fi & lan device with all the lights (either still or blinking) & the phone cable slots]. Said WPA key can be found on the router's relative documents or even on the thing itself.
WPA or WEP
The internet password for your wifi
You can't, the DS lite cannot use WPA encryption. It can only use WEP.
128 bit key.
WPA and WEP are not compatible with each other. They are completely different kinds of encryption.
WPA-PSK2 AES with a long key.
