Overview
In addition to the LAN network, you can define a wireless internal network called a
WLAN (wireless LAN) network. You can configure a WLAN network in either of the
following ways:
•
Wireless Configuration Wizard.
Guides you through the WLAN setup step by
step.
See
Using the Wireless Configuration Wizard
on page 116.
•
Manual configuration.
Offers advanced setup options.
See
Manually Configuring a WLAN
on page 122.
Note:
It is recommended to configure the WLAN via Ethernet and not via a wireless
connection, because the wireless connection could be broken after making a
change to the configuration.
For information on default security policy rules controlling traffic to and from the WLAN,
see
Default Security Policy
on page 168.

About the Wireless Hardware in Your ZoneAlarm
Wireless Router
Your ZoneAlarm wireless router features a built-in 802.11b/g access point that is tightly
integrated with the firewall and VPN.
ZoneAlarm wireless routers support the latest 802.11g standard (up to 54 Mbps) and are
backwards compatible with the older 802.11b standard (up to 11 Mbps), so that both new
and old adapters of these standards are interoperable. SZoneAlarm wireless routers also
support a special Super G mode that allows reaching a throughput of up to 108 Mbps with
Super G compatible stations. For more information on the Super G mode refer to:
ZoneAlarm wireless routers transmit in 2.4GHz range, using dual diversity antennas to
increase the range. In addition, ZoneAlarm routers support a special extended range (XR)
mode that allows up to three times the range of a regular 802.11g access point. XR
dramatically stretches the performance of a wireless LAN, by enabling long-range
connections. The architecture delivers receive sensitivities of up to 105 dBm, over 20 dB
more than the 802.11 specification. This allows ranges of up to 300 meters indoors, and up
to 1 km (3200 ft) outdoors, with XR-enabled wireless stations (actual range depends on
environment).
Wireless Security Protocols
The ZoneAlarm wireless security router supports the following security protocols:
Table 21: Wireless Security Protocols
Security
Protocol
Description
None
No security method is used. This option is not recommended, because it
allows unauthorized users to access your WLAN network, although you can
still limit access from the WLAN by creating firewall rules. This method is
suitable for creating public access points.

Security
Protocol
Description
WEP encryption
In the WEP (Wired Equivalent Privacy) encryption security method, wireless
stations must use a pre-shared key to connect to your network. This method
is not recommended, due to known security flaws in the WEP protocol. It is
provided for compatibility with existing wireless deployments.
Note:
The router and the wireless stations must be configured with the same
WEP key.
WPA-Personal:
password
authentication,
encryption
The WPA-Personal (Wi-Fi Protected Access) security method (also called
WPA-PSK) uses MIC (message integrity check) to ensure the integrity of
messages, and TKIP (Temporal Key Integrity Protocol) to enhance data
encryption. WPA-Personal periodically changes and authenticates encryption
keys. This is called
rekeying
.
This option is recommended for small networks, which want to authenticate
and encrypt wireless data.
Note:
The router and the wireless stations must be configured with the same
passphrase.
WPA2 (802.11i)
The WPA2 security method uses the more secure Advanced Encryption
Standard (AES) cipher, instead of the RC4 cipher used by WPA and WEP.
When using the WPA-Personal security methods, the ZoneAlarm enables you
to restrict access to the WLAN network to wireless stations that support the
WPA2 security method. If this setting is not selected, the ZoneAlarm router
allows clients to connect using both WPA and WPA2.
