4.2.2 LAN
A Local Area Network (LAN) is a shared communication system to which many computers
are attached and is limited to the immediate area, usually the same building or floor of a
building.
Router Local IP
IP Address:
Enter the IP address of ADSL Router in dotted decimal notation, for example,
192.168.1.254 (factory default).
IP Subnet Mask:
The default is 255.0.0.0. User can change it to other such as
255.255.255.0.Type the subnet mask assigned to you by your ISP (if given).
Dynamic Route:
Select the RIP version from RIP-1, RIP-2B and RIP-2M.
RIP Direction:
Select the RIP direction from None, Both, In Only and Out Only.
Multicast:
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data. The BIPAC
5102 Series supports both IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable
it

DHCP
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server.
DHCP:
If set to
Enable
, your BIPAC 5102 Series can assign IP addresses, an IP default gateway
and DNS servers to Windows 95, Windows NT and other systems that support the DHCP
client.
If set to
disabled
, the DHCP server will be disabled.
If set to
Relay
, the BIPAC 5102 Series acts as a surrogate DHCP server and relays DHCP
requests and responses between the remote server and the clients. Enter the IP address of
the actual, remote DHCP server in the Remote DHCP Server field in this case.
When DHCP is used, the following items need to be set.
Starting IP Address:
This field specifies the first of the contiguous addresses in the IP
address pool.
IP Pool Count:
This field specifies the size or count of the IP address pool.
Lease Time:
The current lease time of client.
Primary DNS Server:
Enter the IP addresses of the DNS servers. The DNS servers are
passed to the DHCP clients along with the IP address and the subnet mask.
Secondary DNS Server:
Enter the IP addresses of the DNS servers. The DNS servers
are passed to the DHCP clients along with the IP address and the subnet mask.

4.2.3 Wireless
802.11g is only supported for the BiPAC 5102G
.
This section introduces the wireless LAN and some basic configurations. Wireless LANs can
be as simple as two computers with wireless LAN cards communicating in a peer-to-peer
network or as complex as a number of computers with wireless LAN cards communicating
through access points which bridge network traffic to the wired LAN.

Wireless LAN
Access Point:
Default setting is set to
Activated
.
If you do not have any wireless, both
802.11g and 802.11b, device in your network, select
Deactived.
SSID:
The SSID is the unique name of a wireless access point (AP) to be distinguished
from another.
For security propose, change the default
wlan-ap
to
a unique ID name to the
AP which is already built-in to the router’s wireless interface. It is case sensitive and must
not excess 32 characters. Make sure your wireless clients have exactly the SSID as the
device, in order to get connected to your network.
Broadcast SSID:
Select
Yes
to hide the SSID in so a station cannot obtain the SSID
through passive scanning. Select
No
to make the SSID visible so a station can obtain the
SSID through passive scanning.
Channel ID:
The range of radio frequencies used by IEEE 802.11b/g wireless devices is
called a channel. Select a channel from the drop-down list box.
Authentication Type:
To prevent unauthorized wireless stations from accessing data
transmitted over the network, the router offers highly secure data encryption, known as
WEP.&WPA. If you require high security for transmissions, there are two alternatives to
select from:
64-bit WEP and 128-bit WEP
. WEP 128 will offer increased security over WEP
64.
You can disable or enable with WPA or WEP for protecting wireless network. The default
type of wireless is
disabled
and to allow all wireless computers to communicate with the
access points without any data encryption
Advanced Setting
Beacon interval:
The Beacon Interval value indicates the frequency interval of the
beacon. Enter a value between 20 and 1000. A beacon is a packet broadcast by the Router
to synchronize the wireless network.
RTS/CTS Threshold:
The RTS (Request To Send) threshold (number of bytes) for
enabling RTS/CTS handshake. Data with its frame size larger than this value will perform
the RTS/CTS handshake. Setting this attribute to be larger than the maximum MSDU (MAC
service data unit) size turns off the RTS/CTS handshake. Setting this attribute to zero turns
on the RTS/CTS handshake
Enter a value between 1500 and 2347..
Fragmentation Threshold:
The threshold (number of bytes) for the fragmentation
boundary for directed messages. It is the maximum data fragment size that can be sent.
Enter a value between 256 and 2346.
DMIT:
This value, between 1 and 255, indicates the interval of the Delivery Traffic
Indication Message (DTIM).
802.11b/g:
The default setting is
802.11b+g
(Mixed mode). If you do not know or have
32
Page 35 / 64
both 11g and 11b devices in your network, then keep the default in
mixed mode
.
From the
drop-down manual, you can select
802.11g
if you have only 11g card.
If you have only 11b
card, then select
802.11b
.
Wireless MAC Address Filter
The MAC filter screen allows you to configure the router to give exclusive access to up to 32
devices (Allow Association) or exclude up to 32 devices from accessing the router (Deny
Association). Every Ethernet device has a unique MAC (Media Access Control) address.
The MAC address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:AA:BB:00:00:02. You need to know the MAC address of the
devices to configure this screen.
To change your router’s MAC filter settings, click Wireless LAN, MAC Filter to open the MAC
Filter screen. The screen appears as shown.
.
Active:
Select
Actived
to enable MAC address filtering.
Action:
Define the filter action for the list of MAC addresses in the MAC address filter
table.
Select
Deny Association
to block access to the router, MAC addresses not listed will be
allowed to access the router. Select
Allow Association
to permit access to the router, MAC
addresses not listed will be denied access to the router.
MAC Address:
Enter the MAC addresses (in XX:XX:XX:XX:XX:XX format) of the
wireless station that are allowed or denied access to the router in these address fields.
WEP
Key 1 to Key 4:
Enter the key to encrypt wireless data. To allow encrypted data
transmission, the WEP Encryption Key values on all wireless stations must be the same as
the router. There are four keys for your selection. The input format is in HEX style, 5 and 13
HEX codes are required for 64-bitWEP and 128-bitWEP respectively.
If you chose
WEP 64-bits
, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose
WEP 128-bits
, then enter 13 ASCII characters or 26 hexadecimal characters
