9. As shown in Figure 5-18, the Basic Settings screen for your 5 GHz/802.11a
wireless products will appear. Enter your wireless network’s SSID and
select the channel at which the network broadcasts its wireless signal. Then,
click the Next button to continue.
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 characters, which may be any
keyboard character. The default SSID, linksys-a, should be changed for
greater security. Make sure this setting is the same for all points in your
wireless network.
Channel. Select
the appropriate
channel from
the list provided
to correspond
with your net-
work settings,
between 36 and
64. All points in
your wireless
network must
use the same
channel in order
to function cor-
rectly.
10. At this point, the configura-
tion performed with the
Setup Wizard is complete, as
shown in Figure 5-19. You
can register the Router
online by clicking the
Register Online button. To
configure any other Access
Points in your network, you
can run this Setup Wizard
again. Click the Exit button
to exit the Setup Wizard.

8. As shown in Figure 5-17, the Basic Settings screen for your 2.4GHz/54g
(802.11g-draft) wireless products will appear. Enter the Network Mode,
SSID, and the channel at which the network broadcasts its wireless signal.
Then, click the Next button to continue.
Network Mode. Since Wireless-G products are backwards compatible with
802.11b products, this mode is provided in the event you wish to incorpo-
rate 802.11b products into you Wireless-G wireless network. If you are
using both Wireless-G and 802.11b products in your network, select Mixed
mode. You may experience reduced networking speeds in Mixed mode, as
the speed must compensate for both types. If you are only using Wireless-
G products in your network, select G-Only mode.
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 characters, which may be any
keyboard character. The default SSID, linksys-g, should be changed for
greater security. Make sure this setting is the same for all points in your
wireless network.
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.

3. The web-based utility will appear with the Setup tab selected. Based on the
setup instructions from your ISP, you may need to provide the Host Name
and Domain Name (usually cable ISPs require them). These fields allow
you to provide a host name and domain name for the Router and are usual-
ly left blank.

on the Setup screen. The default values are 192.168.1.1 for the IP Address
and 255.255.255.0 for the Subnet Mask.
4. The Router supports four connection types: Automatic Configuration -
DHCP (obtain an IP automatically), Static IP, PPPoE, and PPTP. These
types are listed in the drop-down menu for the Configuration Type setting.
Each Setup screen and available features will differ depending on what kind
of connection type you select. Proceed to the instructions for the connec-
tion type you are using, and then continue to step 5.
IMPORTANT: If you have previously enabled any Internet-sharing
proxy server software on any of your PCs, you must disable it now.
Some examples of Internet-sharing software are Internet LanBridge,
Wingate, ICS, and Sygate. To disable your Internet-sharing software:
• If you are running Netscape Navigator, click Edit, Preferences,
Advanced, and Proxies. Click Direct Connection to the Internet.
• If you are running Internet Explorer 5.x or higher, click Tools,
Settings, Control Panel, Internet Options, Connections, and
LAN Settings. Remove checkmarks from all three boxes. Click the

Chapter 6: Configuring the
Router’s Basic Settings with the
Web-Based Utility
This chapter will show you how to configure the Router to function in your
network and gain access to the Internet through your Internet Service Provider
(ISP). Detailed description of the Router’s web-based utility can be found in
“Chapter 7: The Router’s Web-based Utility.”
The instructions from your ISP tell you how to set up your PC for Internet
access. Because you are now using the Router to share Internet access among
several computers, you will use the setup information to configure the Router
instead of your PC. You only need to configure the Router once using the first
computer you set up.
1. Open your web browser. Enter http://192.168.1.1 (the Router’s default IP
address) in the web
browser’s Address
field, as shown in
Figure 6-1, and
press the Enter key.
2. An Enter Network Password window, shown in Figure 6-2, will appear.
Windows XP users will see a Connect to 192.168.1.1 window, shown in
Figure 6-3. Leave the User Name field empty, and enter admin in lower-
case letters in the Password field
(admin is the default password).
Then, click the OK button.
