Wireless WEP Not Used
WEP stands for wireless equivalency privacy, which is a key-based encryption/security system for wireless networks. This shows the number of packets sensed where WEP (Wireless Equivalency Privacy) encryption was not used.
If you have not enabled WEP on your Access Points, a high number here would be normal. If you have enabled WEP on your Access Points, these are some possible reasons for this event:
Inadvertently, there is a legitimate station trying to access the wireless network that does not have WEP enabled.
You are seeing cross-traffic from another wireless network within the range of your APs.
A malicious user is trying to gain unauthorized access to your wireless network.
