Wireless port settings
Note: This feature is only supported on the Shiva 1100 VPN Gateway.
The Shiva VPN Gateway can create a wireless network for connection of client
computers that have wireless network cards. The Shiva VPN Gateway supports both
the 802.11b and 802.11g standards.
An important note about wireless security
The wireless network created by the Shiva VPN Gateway may extend beyond the
physical boundaries of your location. Therefore, it is important to properly secure
access to the wireless network and to enable protection for all wireless transmissions
using the Shiva VPN Gateway’s wireless security features. This will ensure that
rouge users are uanble to compromise your network or spy on its transmissions.
Wireless network performance
The Shiva VPN Gateway can create a wireless network (called a cell) in a radius of
up to 300 feet. The quality of the wireless signal in this cell is governed by a number
of factors, including:
• Intervening obstructions: Each obstruction between the Shiva VPN Gateway
and a wireless client station will reduce the signal strength. Some materials,
(wood and plaster) have less of an effect than others (concrete, brick). Metal
creates the most trouble for wireless signals (metal doors, reinforced concete
walls, elevator shafts).
• Electircal devices: Any device that generates RF noise (electric motors,
microwaves, monitors, power supplies) can affect wireless performance. For
maximum performance it is best to install the Shiva VPN Gateway at least 5 feet
away from these types of devices.
• 2.4 GHz devices: Other device using the 2.4 GHz frequency band can
dramatically interfere with wireless operation. This includes other wireless
access points, security systems, and wireless phones. If other wireless access
points are operating in the area, you can adjust the operating channel of the
Shiva VPN Gateway to minimize interference.
