Chapter 4 Basic Wireless Device Configuration

Configuring Wireless Settings

Read Without VLANs, encryption settings (WEP and ciphers) apply to an interface, such as the 2.4-GHz radio, and you cannot use more than one encryption setting on an interface. For example, when you create an SSID with static WEP with VLANs disabled, you cannot create additional SSIDs with WPA authentication because the SSIDs use different encryption settings. If you find that the security setting for an SSID conflicts with the settings for another SSID, you can delete one or more SSIDs to eliminate the conflict.

Security Types

Table 4-1describes the four security types that you can assign to an SSID.
