1.2.5 Pre-Configured SSID Profiles
The ZyXEL Device has two pre-configured SSID profiles.
1 VoIP_SSID. This profile is intended for use by wireless clients requiring the highest
QoS (Quality of Service) level for VoIP (Voice over IP) telephony and other applications
requiring low latency. The QoS level of this profile is not user-configurable. See Section
5.3.1 on page 69 for more information on QoS.
2 Guest_SSID. This profile is intended for use by visitors and others who require access
to certain resources on the network (an Internet gateway or a network printer, for
example) but must not have access to the rest of the network. Layer 2 isolation is enabled
(see Section 8.1 on page 105), and QoS is set to NONE. Intra-BSS traffic blocking is
also enabled (see Section 5.1.1 on page 67). These fields are all user-configurable.
1.3 Ways to Manage the ZyXEL Device
Use any of the following methods to manage the ZyXEL Device.
• Web Configurator. This is recommended for everyday management of the ZyXEL Device
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• SMT. System Management Terminal is a text-based configuration menu that you can use
to configure your device. Use Telnet to access the SMT.
• FTP for firmware upgrades and configuration backup and restore.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this
User’s Guide.
1.4 Good Habits for Managing the ZyXEL Device
Do the following things regularly to make the ZyXEL Device more secure and to manage it
more effectively.
• Change the password often. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the ZyXEL Device to its
factory default settings. If you backed up an earlier configuration file, you won’t have to
totally re-configure the ZyXEL Device; you can simply restore your last configuration.
