    . Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. NWD-270N User's Guide 93

    . By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. . NWD-270N User's Guide 97

    , PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco. LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. 98 NWD-270N User's Guide

    . If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not. Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2. NWD-270N User's Guide 99
