What wireless security modes does my 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.

The telephone port won’t work or the telephone lacks a dial tone.

Check the telephone connections and telephone wire.

I can access the Internet, but cannot make VoIP calls.

The PHONE light should come on. Make sure that your telephone is connected to the PHONE port.

You can also check the VoIP status in the System Info screen. 

If the VoIP settings are correct, use speed dial to make peer-to-peer calls. If you can make a call 
using speed dial, there may be something wrong with the SIP server, contact your VoIP service 
provider.
