DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the modem router, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router forwards your request to the ISP.

Figure 5-7 How to Configure Universal Plug and Play Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network. 1.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual • Advertisement Period. The advertisement period is how often the modem router advertises (broadcasts) its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations might compromise the freshness of the device status but can significantly reduce network traffic.

Configure the DG834N modem router (AP 1) on LAN Segment 1 in point-to-point bridge mode. 2. Configure the other access point (AP 2) on LAN Segment 2 in point-to-point bridge mode.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual 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.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual 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 DG834N 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.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual How to Configure a Repeater with Wireless Client Association In the repeater mode with wireless client association, the DG834N 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 DG834N modem router as the parent by entering the address of a “child” access point.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual 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.

Chapter 6 Troubleshooting This chapter provides information about troubleshooting your DG834N RangeMaxTM NEXT Wireless ADSL2+ Modem Router. After each problem description, instructions are provided to help you diagnose and solve the problem. For the common problems listed, go to the section indicated. • Is the router on? Go to “Basic Functioning” on page 6-1. • Have I connected the router correctly? Go to “Basic Functioning” on page 6-1. • I cannot access the router’s configuration with my browser.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual c. The WAN port LED is lit. d. The Wireless LED is lit. If a port’s LED is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the LED is amber. If any of these conditions does not occur, refer to the appropriate following section.
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual LAN or Internet Port LED Is Not On If either the LAN LEDs or Internet LED does not light when the Ethernet connection is made, check the following: • Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation. • Make sure that power is turned on to the connected hub or workstation. • Make sure that you are using the correct cable when connecting the router’s Internet ADSL port.
