The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2
If your ISP dynamically assigns the DNS server IP addresses (along with the Device’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address
2001:0db8:1a2b:0015:0000:0000:1a2f:0000
.
IPv6 addresses can be abbreviated in two ways:
•
Leading zeros in a block can be omitted. So
2001:0db8:1a2b:0015:0000:0000:1a2f:0000
can
be written as
2001:db8:1a2b:15:0:0:1a2f:0
.
•
Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So
2001:0db8:0000:0000:1a2f:0000:0000:0015
can be
written as
2001:0db8::1a2f:0000:0000:0015
,
2001:0db8:0000:0000:1a2f::0015
,
2001:db8::1a2f:0:0:15
or
2001:db8:0:0:1a2f::15
.
IPv6 Prefix and Prefix Length
Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An
IPv6 prefix length specifies how many most significant bits (start from the left) in the address
compose the network address. The prefix length is written as “/x” where x is a number. For
example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (
2001:db8
) is the subnet prefix.

What You Can Do in this Chapter
This section describes the Device’s
Wireless
screens. Use these screens to set up your Device’s
wireless connection.
•
Use the
General
screen to enable the Wireless LAN, enter the SSID and select the wireless
security mode (
Section 6.2 on page 74
).
•
Use the
More AP
screen to set up multiple wireless networks on your Device (
Section 6.3 on
page 82
).
•
Use the
MAC Authentication
screen to allow or deny wireless clients based on their MAC
addresses from connecting to the Device (
Section 6.4 on page 86
).
•
Use the
WPS
screen to enable or disable WPS, view or generate a security PIN (Personal
Identification Number) (
Section 6.5 on page 87
).
•
Use the
WMM
screen
to enable Wi-Fi MultiMedia (WMM) to ensure quality of service in wireless
networks for multimedia applications (
Section 6.6 on page 88
).
•
Use the
WDS
screen to set up a Wireless Distribution System, in which the Device acts as a
bridge with other ZyXEL access points (
Section 6.7 on page 89
).
•
Use the
Others
screen to configure wireless advanced features, such as the RTS/CTS Threshold
(
Section 6.8 on page 91
).
•
Use the
Channel Status
screen to scan wireless LAN channel noises and view the results
(
Section 6.9 on page 93
).

What You Need to Know
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and
receive information over the airwaves, wireless networking devices exchange information with one
another. A wireless networking device is just like a radio that lets your computer exchange
information with radios attached to other computers. Like walkie-talkies, most wireless networking
devices operate at radio frequency bands that are open to the public and do not require a license to
use. However, wireless networking is different from that of most traditional radio communications in
that there a number of wireless networking standards available with different methods of data
encryption.
Finding Out More
See
Section 6.10 on page 93
for advanced technical information on wireless networks.

The General Screen
Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode.
Note: If you are configuring the Device from a computer connected to the wireless LAN
and you change the Device’s SSID, channel or security settings, you will lose your
wireless connection when you press
Apply
to confirm. You must then change the
wireless settings of your computer to match the Device’s new settings.

Band
This shows the wireless band which this radio profile is using.
2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients.
5 GHz networks use higher frequencies with less interferences than 2.4 GHz networks and
can offer higher speeds. However, 5 GHz signals do not penetrate solid objects like walls as
well as 2.4 GHz signals can do. It is easy to get signal attenuation if there are many walls
between the Device and a client. 5 GHz is used by IEEE 802.11a/n/ac wireless clients.
