Configuration Type.
Select
Static IP Address
if your ISP provided you
with the IP Address, Subnet Mask, and default Gateway address or Select
Automatic Configuration - DHCP
if your ISP assigns IP addresses via
DHCP.
IP Address.
The IP address must be unique to your network. We suggest
you use the default IP address of 192.168.1.245. This is a private IP
address, so there is no need to purchase a separate IP address from your
service provider. Verify the address and click the
Apply
button to save
changes.
Subnet Mask.
The Access Point’s Subnet Mask (or IP Mask) must be the
same as your Ethernet network. Verify this is correct and click the
Apply
button to set it.
Gateway.
If you have assigned a static IP address to the Access Point, then
enter the IP address of your network’s Gateway, such as a router, in the
Gateway
field. If your network does not have a Gateway, then leave this
field blank.

Chapter 6: Configuring the
Wireless-G Access Point
The Access Point has been designed to be functional right out of the box, with
the default settings in the Setup Wizard. However, if you’d like to change these
settings, the Access Point can be configured through your web browser with the
Web-Based Utility. This chapter explains how to configure the Access Point in
this manner.
Open your web browser and type
the IP Address you entered in the
Setup Wizard (the default IP
address is
192.168.1.245
). Press
the
Enter
key and the following
screen, shown in Figure 6-1, will
appear. Leave the
User Name
field blank. The first time you
open the Web-based Utility, use
the default password
admin
. You
can set a new password on the
Password
screen shown in Figure
6-5.
The first screen that appears, shown in Figure 6-2, is the
Setup
tab. This allows
you to change the Access Point’s general settings. Change these settings as
described here, and click the
Apply
button to apply your changes or
Cancel
to
cancel your changes. If you require online help, click the
Help
button.
Firmware Version.
This displays the current version of the Access Point’s
firmware. Firmware should only be upgraded if you experience problems
with the Access Point and can be upgraded from the
Help
tab.
AP Name.
You may assign any name to the Access Point. Unique, memo-
rable names are helpful, especially if you are employing multiple access
points on the same network. Verify this is the name you wish to use and
click the
Apply
button to set it.

Note:
The Access Point is designed to function properly after
using the Setup Wizard. This chapter is provided solely for those
who wish to perform more advanced configuration or monitoring.

Mode.
Select
Mixed
and both Wireless-G and Wireless-B computers will be
allowed on the network, but the speed will be reduced. Select
G-Only
for
maximum speed, but no Wireless-B users will be allowed on the network.
SSID.
The SSID is the unique name shared among all points in a wireless
network. The SSID must be identical for all points in the wireless network.
It is case-sensitive and must not exceed 32 alphanumeric characters, which
may be any keyboard character. Make sure this setting is the same for all
points in your wireless network. For added security, Linksys recommends
that you change the SSID from the default
linksys
to a unique name.
SSID Broadcast.
Allows the SSID to be broadcast on your network. You may
want to enable this function while configuring your network, but make sure
that you disable it when you are finished. With this enabled, someone could
easily obtain the SSID information with site survey software and gain unau-
thorized access to your network. Click
Enable
to broadcast. Click
Disable
to
increase network security and prevent the SSID from being seen on networked
PCs
.
Channel.
Select the appropriate channel from the list provided to corre-
spond with your network settings, between 1 and 11 (in North America). All
points in your wireless network must use the same channel in order to func-
tion correctly.
WEP.
The WEP (Wired Equivalent Privacy) Encryption method is set to
Disable
by default. To enable WEP, click the
Enable
radio button, and then
click the
Edit WEP Settings
button to configure the WEP settings.
SETTING WEP ENCRYPTION:
If the
Disable
radio button is
selected and you click the Edit
WEP Settings
button, then the
screen shown in Figure 6-3 will
appear.
Click the
OK
button to
enable WEP encryption or
Cancel
to return to the
Setup
screen.
Set WEP Encryption through the
Web-based Utility by clicking the
Edit WEP Settings
button on the
Setup
screen as shown in Figure 6-2.
Figure 6-3
This will open the
WEP Keys
screen, Figure 6-4. From this screen, you can select
the type of WEP encryption to use and set the Passphrase for that encryption.
Default Transmit Key
.
Select the number of the key you want to use for
the Access Point to send data. Use the same key for the receiver of data.
WEP encryption
. From the pull-down menu, select
64-bit 10 hex digits
or
128-bit 26 hex digits
for WEP encryption. Higher encryption levels offer
higher levels of security, but may decrease the network speed.
Passphrase.
This will allow you to set a passphrase used to generate a WEP
key. The passphrase is case sensitive and must be 16 or less alphanumeric
characters.
Click the
Generate
button to create the WEP key(s).
Keys 1-4.
WEP key fields allow you to manually enter the WEP encryp-
tion keys. Use hexadecimal characters, which are the letters “A” through
“F” and the numbers “0” through “9”. Do not leave a key field blank and
do not enter all zeroes. For 64-bit WEP encryption, each key must consist
of exactly 10 hexadeciamal characters. For 128-bit WEP encryption, each
key must consist of exactly 26 hexadecimal characters.

Important:
Always remember that each point in your wireless net-
work MUST use the same WEP encryption method and encryption
key, or else your wireless network will not function properly.

Wireless-G Access Point
SETTING THE AP MODE:
The Access Point offers two modes of operation for the 2.4 GHz, draft 802.11g:
Access Point and Wireless Bridge. For all bridging modes, make sure the chan-
nel, SSID, and WEP key settings are the same.
Access Point -
The 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.
Wireless Bridge -
If you are trying to make a wireless connection between
two or more wired networks, as shown in Figure 6-7, select
Wireless
Bridge
. This mode connects two physically separated wired networks with
two access points.
To configure a Wireless Bridge environment, click
Wireless Bridge
and
enter the LAN MAC address of the remote access point in the
Remote
Wireless Bridge’s LAN MAC Addresses
field. The remote access point also
needs to be set up as a Wireless Bridge.
Note:
All devices on each wired network must be connected through a hub
or switch.
