Wireless-N ADSL2+ Modem Router DGN2000 Reference Manual
5-18 Advanced Configuration
v1.0, July 2008
To set up the multi-point bridge configuration shown in Figure5-11:
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 Figure5-11, 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 Figure5-11 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.
