Wireless Equivalent Privacy
(
WEP
) Security is a method by which WLANs protect wireless data
streams. A data stream encrypted with WEP can still be intercepted or eavesdropped upon, but the
encryption makes the data unintelligible to the interloper. The strength of WEP is measured by the
length of the key used to encrypt the data. The longer the key, the harder it is to crack.
802.11b implementations provided 40-bit and 104-bit WEP keys. This is known respectively as 64-
bit and 128-bit WEP encryption. 64-bit is generally not regarded as adequate security protection.
Both key lengths are supported by the Modero product line. Whichever level of WEP you use, it's
crucial to use identical settings (CASE SENSITIVE)--the key length, and the key itself-- on all
devices. Only devices with common WEP settings will be able to communicate. Similarly, if one
device has WEP enabled and another doesn't, they won't be able to talk to each other.
Although the calculations required to encrypt data with WEP can impact the performance of your
wireless network, it's generally seen only when running benchmarks, and not large enough to be
noticeable in the course of normal network usage.
Configuring a Wireless Access Connection
When working with a wireless card, the first step is to configure wireless communication parameters within
the Secondary Connection page. This page only configures the card to communicate to a target WAP (such as
the NXA-WAP200G),
it is still necessary to tell the panel which Master it should be communicating with
.
This "pointing to a Master" is done via the System Connection page where you configure the IP Address,
System Number and Username/Password information assigned to the target Master.
Step 1: Configuring the Panel’s IP Settings
The first step to successfully setting up your wireless card is to configure the IP Settings section of the
Secondary Connection page. The section configures the communication parameters from the Modero panel to
the web.
Wireless communication using a DHCP Address
1.
Select
Protected Setup
>
Secondary Connection
(located on the lower-left) to open the Secondary
Connection page. Wireless communication is set within the IP Settings section of this page (FIG. 53).
2.
Toggle the
DHCP/Static
field (
from the IP Settings section
) until the choice cycles to
DHCP
.
This action
causes
all fields in the IP Settings section (other than Host Name) to be greyed-out.
3.
Press the optional
Host Name
field to open a Keyboard and enter the Host Name information.
4.
Press
Done
after you are finished assigning the alpha-numeric string of the host name.
5.
Do not alter any of these remaining greyed-out fields in the IP Settings section. Once the panel is
rebooted, these values are obtained by the unit and displayed in the
DNS
fields after
power-up.
DHCP will register the unique MAC Address (factory assigned) on the panel and
once the communication setup process is complete, assign IP Address, Subnet
Mask, and Gateway values being communicated to the panel.
