antennas in different directions and check which provides the strongest signal to the wireless
clients.
What wireless security modes does my ZyXEL Device support?
Wireless security is vital to your network. It protects communications between wireless stations,
access points and the wired network.
The available security modes in your ZyXEL device are as follows:
• WPA2-PSK: (recommended) This uses a pre-shared key with the WPA2 standard.
• WPA-PSK: This has the device use either WPA-PSK or WPA2-PSK depending on which security
mode the wireless client uses.
• WPA2: WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption,
authentication and key management than WPA. It requires the use of a RADIUS server and is
mostly used in business networks.
• WPA: Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. It requires the use
of a RADIUS server and is mostly used in business networks.
• WEP: Wired Equivalent Privacy (WEP) encryption scrambles the data transmitted between the
wireless stations and the access points to keep network communications private.
