In addition to WPA and 802.1x, there are the options to enable WEP (Pre-Shared Key) or the new
Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) on your wireless LAN. For WEP (Wired
Equivalent Privacy) security, the SMC2536W-AG Utility supports HEX and ASCII key entries.
For the HEX Key Format, the security is enabled by entering 10-digit keys for the 64-bit WEP
configuration, 26-digit keys for a 128-bit WEP configuration, and 32-digit keys for a 152-bit WEP
configuration. Allowed hex keys are 0-9 and A-F. For the ASCII Key Format, the security is
enabled by entering 5 characters for 64-bit WEP, 13 characters for 128-bit WEP and 16
characters for 152-bit WEP.
Click Pre-Shared Key and select the [Configure] button to enter in WEP keys.
