In 2001, mathematicians showed that WEP is not very strong. A WEP connection could be decoded, with software that can be easily found, within minutes. Because of this finding, IEEE created a new 802.11i group to fix the problems. By 2003, the Wi-Fi Alliance announced that Wi-Fi Protected Access (WPA) would replace WEP, which was a subset of then upcoming 802.11i amendment. Finally in 2004, they made it official and said that it would go ahead. It was part of the full 802.11i standard (also known as WPA2), the IEEE declared that both WEP-40 and WEP-104 are not recommended because they are not secure enough.
