No, MCD products do not support Dynamic WEP.   At present, there are no road map plans to support Dynamic WEP.  Dynamic WEP is vendor proprietary feature and can be compromised due to the weakness of WEP and is not part of the IEEE 802.11 standard.  Any use of WEP even with Dynamic WEP mechanisms is not recommended.  MCD products do support TKIP and "fixed-key WEP" as specified in the 802.11 standard.  AES encryption is recommended.  Fusion 3.00 based products have U.S. Government FIPS 140-2 Level 1 certification on AES.
