Wireless Network Access Point
Authentication Type.
You may choose between
Open System
,
Shared
Key
, and
Both
.
The Authentication Type default is set to
Open System
, in
which the sender and the recipient do NOT share a secret key.
Each party
generates its own key-pair and asks the receiver to accept the randomly-
generated key.
Once accepted, this key is used for a short time only.
Then
a new key is generated and agreed upon.
Shared Key
is when both the
sender and the recipient share a secret key.
Preamble Type.
The preamble defines the length of the CRC block for
communication between the Access Point and the roaming Network Card.
(High network traffic areas should use the shorter preamble type.) Select
the appropriate preamble type and click the
Apply
button to set it.
Basic Rates.
The basic transfer rates should be set depending on the speed
of your wireless network. Verify that you’ve set the correct basic rate for
your wireless network before clicking the
Apply
button.
The
Auto Rate Fall Back
setting should be checked to make your wireless
network flexible for roaming wireless devices. As wireless devices move
away from the Access Point, the transfer rate will automatically fall back to
the most optimum rate allowed.

THE ADVANCED TAB
Before making any changes to the Advanced tab, please check your wireless
settings as these changes will alter the effectiveness of the Wireless Network
Access Point. In most cases, these settings do not need to be changed.
Fragmentation Threshold Value.
The value should remain at its default
setting of
2,346
. If you have decreased this value and experience high pack-
et error rates, you can increase it again, but it will likely decrease overall
network performance. Only minor modifications of this value are recom-
mended.
RTS Threshold Value.
This value should remain at its default setting of
2,346
. Should you encounter inconsistent data flow, only minor modifica-
tions are recommended.

THE MODE TAB
The WAP11 offers three modes of operation: Access Point, Access Point Client,
and Wireless Bridge.
A P
P o i n t
-
T h e
Operational Mode
is
set to
Access Point
by
default. This connects
your wireless PCs to a
wired
network.
In
most cases, no change
is necessary.
38
Wireless Network Access Point
Access Point Client -
A WAP11 set to Access
Point Client mode is
able to talk to one main
WAP11 and wireless
clients within its range.
This mode allows your
WAP11 to act as a client
of a main WAP11. A
LAN attached to your
WAP11 client can then
be wirelessly bridged to
the main WAP11. Enter
the
required
MAC
address of the main
WAP11.
Wireless
Bridge
-
If you are trying to
make a wireless con-
nection between two
wired networks, select
Wireless Bridge
. There
are two options: Point to
Point
and
Point
to
MultiPoint.
39
Note:
In Wireless Bridge mode, the WAP11 can
ONLY
be
accessed by another wireless bridge.
In order for your other
wireless devices to access the WAP11, you must reset it to
Access Point mode.
The two modes are mutually exclusive.

Point to Point
This mode connects two physically separated LAN segments by using two
WAP11 units.
To configure a Point to Point bridged environment:
1.
Click
Point to Point
.
2.
Set the MAC Address of the Access Point in LAN 1 to look for the
MAC Address of the Access Point in LAN 2.
3.
Set the MAC address of the Access Point in LAN 2 to look for the
MAC Address of the Access Point in LAN 1.
4.
On the Operational Mode tab, enter the
Remote MAC Address
of the
remote Access Point. The remote Access Point also needs to be set up
as a Wireless Bridge.
Note:
All devices on each LAN must be connected through a hub or switch.
40
Wireless Network Access Point
41
Point to MultiPoint
This mode allows you to construct a network that has multiple WAP11 units
bridging wirelessly.
To configure a Point to MultiPoint bridged environment:
1.
Click
Point to MultiPoint
for the WAP11 used in LAN 1. No MAC
Address binding is needed.
2.
Set the Access Points in LAN 2 and LAN 3 to Point to Point, and
have them look for the MAC Address of the Access Point in LAN 1.
Only one of the Access Points must be in Point to MultiPoint mode. For all
other bridged Access Points, select the
Point to Point
option, and enter the
Remote MAC Address
of the Access Point set to Point to MultiPoint.
Click the
Apply
button to store the information. A new dialog box will appear.
Click the
Yes
button to accept the changes.

THE SECURITY TAB
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm, as described in the IEEE 802.11 standard. In
order to utilize WEP encryption, all points in your wireless network must have
WEP enabled and be set to the same Key Setting.
WEP (Disable/64-bit/128-bit).
To use WEP encryption, select
Enable
. For
no WEP encryption, select
Disable
. This specific WEP encryption is
unique to Linksys and may conflict with other vendors’ WEP encryption.
Passphrase.
This is the code used when a point on the wireless network wishes
to log on to the network. It is a text string with a maximum of 32 alphanumeric
characters. The WEP Key Settings are based upon the Passphrase determined by
you. Type that here. This passphrase may not work with non-Linksys products
due to possible incompatibility with other vendors’ passphrase generators.
WEP Key Setting.
This setting is the configuration key used in accessing
the wireless network via WEP encryption. To generate an encryption key:
1. Type exactly the same case sensitive Passphrase in the PassPhrase field. For
security purposes, please create your own Passphrase.
2. Click the
Done
button to create the encryption keys. The Passphrase gener-
ates four unique keys.
THE IP SETTING TAB
The IP settings for the Access Point are made from this tab. This is for the
SNMP Configuration Utility use only.
IP Address.
This IP address must be unique to your network. We suggest
you use the default IP address of 192.168.1.250. As this is a private IP
address, there is no need to purchase a separate IP address from your serv-
ice provider. Verify the address and click the
Apply
button to save changes.
IP Mask.
Your Access Point’s Subnet Mask must be the same as your
Ethernet network. Verify this is correct and click the
Apply
button to set it.
DHCP Setting.
Check the box next to
DHCP Enable
to allow it to obtain
a dynamic IP address from a DHCP server. You may also choose how the
WAP11 dynamically obtains an IP address—either
Wireless
or
Ethernet
.
IP Filtering.
For security, click the check box to enable IP filtering, which
allows IP packets only through the Access Point.
Gateway.
This setting only appears when the DHCP client is enabled; it
indicates the status of the gateway and is not user-adjustable.
