This algorithmis also used in plaintext, Dynamic WEP, IEEE 802.1X,and WPA modes. When the authentication algorithm isset to Open System, any client can associate with theaccess point.NOTE Just because a client station is allowed to associatedoes not ensure it can exchange traffic with an accesspoint. A station must have the correct WEP key to beable to successfully access and decrypt data from anaccess point, and to transmit readable data to theaccess point.• Shared key authentication requires the client station tohave the correct WEP key in order to associate withthe access point. When the authentication algorithm isset to Shared Key, a station with an incorrect WEP keywill not be able to associate with the access point.• Both Open system and Shared key. When you selectboth authentication algorithms:- Client stations configured to use WEP in shared keymode must have a valid WEP key to associate withthe access point.- Client stations configured to use WEP as an opensystem (shared key mode not enabled) are able toassociate with the access point, even if they do nothave the correct WEP key.Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide 66
