ESSID is a unique name to
identify the ZyAIR in a wireless
LAN. Enter a descriptive name.
The range of radio frequencies
used by IEEE 802.11b/g wireless
devices is called a channel.
Select a channel ID that is not
already in use by a neighboring
device.
Select None, Basic (WEP) or Extended (WPA-PSK) from the drop-down list box as the level of wireless security.
Choose None security to have no wireless LAN security configured. If you do not enable any wireless security on your
ZyAIR, your network is accessible to any wireless networking device that is within range.
Choose Basic (WEP) security if you want to configure WEP Encryption parameters.
Choose Extended (WPA-PSK) security to configure a Pre-Shared Key. Choose this option only if your wireless clients
support WPA-PSK.
The third screen varies depending on which security level you select.
The wireless stations and ZyAIR must use the same ESSID, channel ID
and WEP encryption key (if WEP is enabled) or WPA-PSK (if WPA-PSK is
enabled) for wireless communication.
3. Choose Basic (WEP) security in the previous screen to setup WEP Encryption parameters.
WEP (Wired Equivalent Privacy)
encrypts data frames before
transmitting over the wireless
network.
The higher the WEP Encryption, the
higher the security but the slower
the throughput.
Select 64-bit or 128-bit from the
WEP Encryption drop-down list.
Select ASCII or Hex WEP key input
method and then follow the on-
screen instructions to set up the
WEP keys.

Pre-Shared Key
Type a pre-shared key to have a more
secure wireless connection than WEP
encryption.
Type from 8 to 63 case-sensitive ASCII
characters.
You can set up the most secure wireless
connection by configuring WPA in the
advanced wireless screen. You need to
configure a RADIUS server to do this.
5. This wizard screen has three variations depending on what encapsulation type you use. Use the
information in Internet Account Information to fill in fields.
Choose Ethernet when the WAN port is
used as a regular Ethernet. Choose from
Standard or a RoadRunner version.
You’ll need User Name, Password and
Login Server IP Address for some
Roadrunner versions.
PPPoE or Point-to-Point Protocol over
Ethernet (PPP over Ethernet) also
functions as a dial-up connection.
Therefore you’ll also need a username
and password and possibly the PPPoE
service name.
Your ISP will give you all needed
information.
Choose PPTP if your service provider uses a DSL terminator with PPTP login. The ZyAIR must have a static IP address in
this case. You’ll also need a login name, associated password, the DSL terminator IP address and possibly a connection ID.
Click Next to continue.
If you change the ZyAIR’s IP address, you must use the new IP address if
you want to access the web configurator again.

0.0.0.0.
DNS Server Address Assignment
Select From ISP if your ISP dynamically assigns DNS server information (and the ZyAIR’s WAN IP address). The field
to the right displays the (read-only) DNS server IP address that the ISP assigns. If you chose From ISP, but the ZyAIR
has a fixed WAN IP address, From ISP changes to None after you click Next.
If you chose From ISP for the second or third DNS server, but the ISP does not provide a second or third IP address,
From ISP changes to None after you click Next.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP address in the field to the
right. If you chose User-Defined, but leave the IP address set to 0.0.0.0, User-Defined changes to None after you
click Next.
If you set a second choice to User-Defined, and enter the same IP address, the second User-Defined changes to
None after you click Next.
Select None if you do not want to configure DNS servers. If you do not configure a system DNS server, you must use
IP addresses when configuring VPN, DDNS and the timeserver.
WAN MAC Address
The WAN MAC address field allows users to configure the WAN port's MAC address by either using the factory default
or cloning the MAC address from a computer on your LAN.
Select Factory Default to use the factory assigned default MAC address. Alternatively, select Spoof this Computer's
