Wired Equivalent Privacy (WEP)

WEP was the standard encryption technology that was used in the early days of Wi-Fi networks. More secure methods, such as WPA have since emerged, but WEP remains an extremely popular choice for encrypted networks. There are two variants of WEP:

●   WEP Open: This is by far the most commonly-used version of WEP. Networks that use this variant don't bother to verify that you have the correct encryption key before allowing you to connect. After all, if you don't have the correct encryption key, you won't be able to communicate with the network anyway.
●   WEP Shared: This variant forces you to prove you have the correct encryption key before it allows you to connect. It does this by sending out some sample text for webConnect to encrypt. If the result that the network gets back is what it expected, then it allows you to connect. Ironically, this is somewhat less secure than WEP Open because the verification process used gives potential intruders a large hint about the contents of the encryption key.

Your device uses the WEP Shared variant.
