A fundamental critique of WEP is its short initialization vector length.

Explanation:
WEP’s vulnerability comes from its initialization vector: it is only 24 bits long and is sent in the clear with every frame. Because the IV space is so small, IV values repeat quickly on real networks. If the same keystream is used for different packets, the resulting ciphertexts leak relationships between the plaintexts and allow attackers to perform statistical or known-plaintext attacks to recover information about the key or plaintext. This IV reuse weakness is a fundamental flaw in WEP’s design, making the statement true.
