5. Turn on your PC(s). If this router works correctly, you will notice that the PWR and
WLAN LEDs are lit; WAN and LAN LEDs are flashing, till you power down the
AP. The DIAG will be lit several seconds and then turn dark.
Preparing Your Network
In this chapter, you’ll learn what should be done first before configuring your
router.
efore you can configure your router, you need to set up all the computers on your
network for TCP/IP networking. You also need to know certain information from your
ISP.
Configuring Windows for IP Networking
You need to configure each computer in your network for TCP/IP networking. If you plan to
use the DHCP feature (recommended), you should configure each computer to receive an IP
address automatically. See the procedure below for instructions.
If you don’t plan to use DHCP, you’ll need to manually assign an IP address to each computer.
Refer to your Windows documentation for instructions on how to do this.
TO CONFIGURE WINDOWS TO RECEIVE DYNAMIC IP ADRESSES:
1. Click Start, then choose Settings -> Network and Dial-up Connections ->
[name of your ISP connection].
A Status dialog box will appear:

4. Click Obtain an IP address automatically and Obtain DNS server address
automatically.
5. Click OK. You may need to restart your computer.
Note
This procedure applies to Windows 2000 operating systems only. For Windows
95/98/ME, Windows NT, or Windows XP, consult your Windows
documentation.

Collecting ISP Information
You will need to find out some information from your ISP before you can configure your router,
such as:
"Has your ISP assigned you a static IP address, or will they assign one to you dynamically?
If they have given you a static IP, what is it?
"Does your ISP use PPPoE? If so, what is your PPPoE username and password?
Call your ISP if you’re not sure of the answers to these questions.

Basic Functions
Basic administrative functions include Setup.
he WL5041 Router comes with a web-based tool that you can use to set up and
customize the router settings. You can access this tool from any computer on your
network.
Note
For best results, use Microsoft Internet Explorer version 5.0 or later.
TO OPEN THE WEB-BASED ADMIN TOOL:
1. Open a browser on your PC.
2. Type http://192.168.1.1 in the Address field:

A logon dialog box will appear:
Figure 5. Username/Password Dialog Box
3. Leave User Name field blank. Then, type a Password and click OK. The default
password is admin.
The WL5041 Router Admin Tool will appear.
Note
The web-based Admin Tool will log you out after a certain period of idle time. If
this happens, you will need to re-enter your username and password. If users have
changed default LAN IP Address (192.168.1.1) to someone and forget the IP
address later, you can use the IP alias (192.168.168.1) to enter the Web configuration
tool. Of course you should make sure that your network device IP address is the
same subnet with 192.168.168.1. For example, ipaddress:192.168.168.5 subnet
mask:255.255.0.0

10
Basic
The Basic screen allows you to configure the basic operation of the router.
Although most users will be able to accept the default settings, every Internet Service Provider
(ISP) is different. Check with your ISP if you're not sure which settings they require.
The Basic screen is shown in the figure below.
Figure 6. Basic Screen

11
Note
The graphics shown in this manual may differ slightly from your router’s screens.
The images that appear here are provided as examples only.
TO CONFIGURE SETUP PARAMETERS:
1. LAN MAC Address: Shows the MAC Address (also known as the Ethernet address)
of the LAN interface.
2. Review the LAN IP Address information and change if necessary.
These two fields show the Device IP Address and Subnet Mask as seen by others on
your Local Area Network (LAN). Most users will not need to change these values (default
IP is 192.168.1.1, subnet mask is 255.255.255.0).
Note
If you change the LAN IP Address with the DHCP server running, you'll need
to restart your client machines. If you change the LAN IP Address without the
DHCP server running, you'll need to manually reconfigure your clients' IP
addresses.
3. LAN DHCP Server: DHCP is Eabled by factory default. If you have already a
DHCP Server in your network, or you don’t want a DHCP Server, then please select
the Disabled radio button.
Note
If you don’t enable DHCP on your router, you’ll need to manually configure an IP
address for each computer on your network.
4. Setup the LAN DHCP Starting IP Address and Ending IP Address.
I. Make sure there is not already a DHCP server running on your network.
II. Make sure that each computer on your network is configured to receive an IP
address automatically.
III. On the DHCP screen, click Enable.
IV. Type the LAN DHCP Starting IP Address. The address you specify will be the
first IP address that can be assigned to a computer on the network.

12
V. Type the LAN DHCP Ending IP Address. The address you specify will be the
last IP address that can be assigned.
VI. Type the LAN Lease Time. Set the number of seconds DHCP leases should be
valid for. The default value is 86400, which means one day.
Example
If you choose 192.168.1.51 as the starting address and 192.168.1.100 as the
ending address, the DHCP server will assign addresses to network clients that
are between 192.168.1.51 and 192.168.1.100.
5. LAN Spanning Tree Protocol: Enables the use of the Ethernet 802.1d Spanning
Tree Protocol to eliminate bridging loops across the LAN interfaces.
WAN Setting:
The second part of the Basic screen is the configuration of WAN. The figure is as the
following.
1. WAN Host Name: Some ISPs require that a host name be provided when requesting an IP
address through DHCP Server. You may have to check with your ISP to see if your
broadband Internet service has been configured with a host name. In most case, leaving the
field blank will work.
2. WAN Domain Name: Set the domain name to be provided to LAN clients who request an
IP address through DHCP Server. You may have to check with your ISP to see if your
broadband Internet service has been configured with a domain name. In most case, leaving
the field blank will work.
3. WAN MAC Address: Some ISPs need that a specific MAC address be used. This field
allows you to set the MAC address of the WAN interface.
Figure 7. Basic Screen (2)

13
Warning
Please don’t change the default WAN MAC Address unless your ISP request you to
do this action.
4. WAN IP Address: Set the IP address of the WAN interface.
5. WAN Subnet Mask: Set the IP subnet mask of the WAN interface.
6. WAN Default Gateway: Set the IP address of the default gateway on the WAN.
7. WAN DNS Servers: The DNS (Domain Name System) is how the Internet translates
domain or website names into Internet address or URLs. Your ISP will provide you with at
least one DNS Server IP address. If you wish to use another one, type that IP address in one
of these fields. You can type up to three DNS Server IP address here. The Router will use
these for quicker access to functioning DNS servers.
8. WAN WINS Servers: The Windows Internet Naming Service (WINS) manages each PC’s
interaction with the Internet. If you use a WINS Server, enter that server’s IP address here.
Otherwise, leave this blank.
9. WAN Protocol: Set the method to use to obtain an IP address for the WAN interface.
PPPoE and Routing Setting:
PPPoE (Point-to-Point Protocol over Ethernet) is a protocol used by many ADSL Internet
Service Providers. WL5041 has a free client for Linux, NetBSD and Solaris systems to connect to
PPPoE service providers. The setting screen is shown as the figure below.
1. PPPoE Username: Set the username to use when authenticating with a PPPoE server.
2. PPPoE Password: Set the password to use when authenticating with a PPPoE server.
Figure 8. Basic Screen (3)

14
3. PPPoE Keep Alive: If this function is enabled, the PPPoE link should be automatically
restored when the connection is disconnected. This setting has no effect if PPPoE
Connect on Demand is Enable.
4. PPPoE Connect on Demand: If this function is enabled, the PPPoE link should be
automatically disconnected when no traffic has been observed for the period specified by
PPPoE Max Idle Time.
5. PPPoE Max Idle Time: Set the number of seconds to wait before disconnecting the
PPPoE link if PPPoE Connect on Demand is Enable.
6. PPPoE MRU: Set the maximum number of bytes that the PPPoE interface will receive
in a single Ethernet frame.PPPoE MTU: Set the maximum number of bytes that the
PPPoE interface will transmit in a single Ethernet frame. Make sure the value is 1400 or
smaller than 1400. Router Username: Set the username for access to these
configuration pages. Leave this field and Router Password blank to disable access
control.Router Password: Set the password for access to these configuration pages.
Leave this field and Router Username blank to disable access control.Router WAN
Port: Set the WAN port to use the remote access to these configuration pages. Leave
this field blank to disable remote access.Router Mode: Router Mode is default. If you
select Access Point Mode that is disabling LAN DHCP Server, LAN Spanning Tree
Protocol, and WAN Protocol. Firewall: Connections from the WAN are allowed if
the Firewall is disabled.Note
If your ISP has provided the DHCP functionality, you should select the Router
Mode. The capability of Access Point Mode is similar to the single Hub, and
doesn’t support the DHCP function.
The other relevant setting:
1. Time Zone: Set the Time Zone of this locale.
2. NTP Server: Set the IP address of the NTP Server to use for time synchronization.
3. Syslog IP Address: System log message will be sent to this IP address.
4. UPnP: Set whether Universal Plug and Play (UPnP) is enabled.
Figure 9. Basic Screen (4)

Status
The Status screen is a read-only display that gives you information about your router. The data
displayed may change depending on your current configuration.
The Status screen is shown in the figure below.
Figure 10. Status Screen
The displayed data may include:
!Local Time: Showing the local time as kept by the router.
!Connection Log: Showing a log of recent connection attempted.
!Active DHCP Leases: You can view the list of PCs that are given IP address by the router.
For each PC, the list shows the hostname, IP address, MAC address and the amount of
DHCP client lease time left.

17
Filters
Use the Filters screen to create and apply filters that can selectively allow
traffic to pass in and out of your network.
Warning
Overwriting the factory default filters may result in your network clients not being
able to access the Internet. When you define new filters, we recommend that you
choose an empty row.
The Filters screen is shown in the figure below.
Figure 11. Filter Screen (1)
1. LAN MAC Filter Mode: Select whether clients with the specified MAC address are allowed
or denied access to the router.
2. LAN MAC Filters: Filter packets from LAN machines with the specified MAC addresses.
If no filters are
enabled, all traffic
will be blocked.

Routing
Routing is the act of moving information across an Internet from a source to a destination. Along
the way, at least one intermediate node typically is encountered. Routing is often contrasted with
bridging, which might seem to accomplish precisely the same thing to the casual observer. The
primary difference between these two are bridging occurs at Layer 2 (the link layer) of the OSI
reference model, whereas routing occurs at Layer 3 (the network layer). This distinction provides
routing and bridging with different information to use in the process of moving information from
source to destination, so these two functions accomplish their tasks in different ways. The
Routing screen is shown in the figure below.
