A computer on either LAN segment should be able to connect to the Internet or share files and
printers of any other PCs or servers connected to LAN Segment 1 or LAN Segment 2.
How to Configure a Multi-Point Bridge
Multi-point bridge mode allows a modem router to bridge to multiple peer access points
simultaneously. As a bridge, wireless client associations are disabled—only wired clients can be
connected. Multi-point bridge mode configuration includes the following steps:
Entering the MAC addresses of the other access points in the fields provided.
Setting the other bridge-mode access points to Point-to-Point Bridge mode, using the MAC
address of this DGN2000 as the Remote MAC Address.
Using wireless security to protect this traffic.
The following figure shows an example of a multi-point bridge mode configuration.

To set up the multi-point bridge configuration shown in
Figure 5-11
:
1.
Configure the operating mode of the modem routers.
Because it is in a central location, configure the DGN2000 modem router (AP 1) on LAN
Segment 1 in point-to-multi-point bridge mode, and enter the MAC addresses of
AP-2 and AP-3 in the
Remote MAC Address 1
and
Remote MAC Address 2
fields.
Configure the access point (AP2) on LAN Segment 2 in point-to-point bridge mode with
the remote MAC address of the DGN2000 modem router.
Configure the access point (AP3) on LAN Segment 3 in point-to-point bridge mode with
the remote MAC address of the DGN2000 modem router.
2.
Disable the DHCP server on AP2 and AP3. AP1 will then be the DHCP server.
3.
Verify the following for all access points:
The LAN network configuration of the modem router and other access points are
configured to operate in the same LAN network address range as the LAN devices.
Only one AP, the DGN2000 modem router in
Figure 5-11
, is configured in point-to-multi-
point bridge mode; all the others are in point-to-point bridge mode.
All APs, including the DGN2000 modem router, must be on the same LAN. That is, all the
AP LAN IP addresses must be in the same network.
If you are using DHCP, all access points should be set to
Obtain an IP address
automatically (DHCP Client)
in the IP Address Source section of the Basic IP Settings
screen.
All APs, including the DGN2000 modem router, must use the same SSID, channel,
authentication mode, if any, and WEP security settings if security is in use.
All point-to-point APs must have the MAC address of AP 1 (the DGN2000 modem router
in the previous figure) in the
Remote AP MAC address
field.
4.
Verify connectivity across the LANs.
A computer on any LAN segment should be able to connect to the Internet or share files
and printers with any other PCs or servers connected to any of the three LAN segments.
Note:
Wireless stations configured as they are in
Figure 5-11
will not be able to connect
to the modem router or access points. If you require wireless stations to access any
LAN segment, you can use additional access points configured in wireless access
point mode in any LAN segment.

How to Configure a Repeater with Wireless Client Association
In the repeater mode with wireless client association, the DGN2000 modem router sends all traffic
to a remote AP. For the repeater mode, you must enter the MAC address of the remote “parent”
access point. Alternatively, you can configure the DGN2000 modem router as the parent by
entering the address of a “child” access point. Note that the following restrictions apply:
You
do not
have the option of disabling client associations with this DGN2000 modem router.
You cannot configure a sequence of parent/child APs. You are limited to only one parent AP,
although if the DGN2000 modem router is the parent AP, it can connect with up to four child
APs.
The following figure shows an example of a Repeater mode configuration.
To set up a repeater with wireless client association:
1.
Configure the operating mode of the devices.
Configure AP 1 (the DGN2000 modem router in
Figure 5-12
) on with the MAC address of
AP 2 and AP 3 in the first two
Remote MAC Address
fields.
Configure AP 2 with the MAC address of AP 1 in the
Remote MAC Address
field.
Configure AP 3 with the MAC address of AP 1 in the
Remote MAC Address
field.

2.
Verify the following for both access points:
The LAN network configuration of each AP is configured to operate in the same LAN
network address range as the LAN devices.
The APs must be on the same LAN. That is, the LAN IP addresses for the APs must be in
the same network.
If you are using DHCP, AP devices should be set to
Obtain an IP address automatically
(DHCP Client)
in the IP Address Source section of the Basic IP Settings screen.
AP devices must use the same SSID, channel, authentication mode, and encryption.
3.
Verify connectivity across the LANs. A computer on any LAN segment should be able to
connect to the Internet or share files and printers with any other PCs or servers connected to
any of the three WLAN segments.
Displaying and Configuring Advanced WPS Settings
To display and specify advanced WPS settings:
1.
Log in to the modem router at its default LAN address of
with its default
user name of
admin
and default password of
password
, or using whatever user name,
password, and LAN address you have chosen for the modem router.
Note:
The advanced WPS settings cannot be displayed if you have selected WEP as the
security option.
