TKIP had to use RC4 as its cipher because it needs to make sure that it would run on WEP legacy hardware. Although, TKIP prevents many attacks that WEP was vulnerable for (such as recovery attacks), it is still vulnerable for some other minor attacks such as Beck-Tews attack and Ohigashi-Morii attack.
