modem router. This is usually the case. For help with DHCP, see the documentation that came with
your computer, or see the link to the online document that you can access from “Preparing Your
Network” in Appendix B.
Your ISP should have provided you with all the information needed to connect to the Internet. If
you cannot locate this information, you can ask your ISP to provide it.
Logging In to the Wireless Modem Router
You can log in to the modem router to view or change its settings.
Note: Your computer must be configured for DHCP. For help with configuring DHCP, see
the documentation that came with your computer or see the link to the online document that you can access from “Preparing Your Network” in Appendix B.
To log in to the modem router:

only from the MAC address of that computer. This feature
allows your modem router to masquerade as that computer by
“cloning” its MAC address.
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. The modem router will
capture and use the MAC address of the computer that you
are now using. You must be using the one computer that is
allowed by the ISP.
• Use This MAC Address. Enter the MAC address that you
want to use.

ADSL Settings
Note: For information about how to install ADSL filters, see the NETGEAR Router Setup
Manual.
The default ADSL settings of your modem router work fine for most ISPs. However, some ISPs
use a specific multiplexing method and virtual circuit number for the virtual path identifier (VPI)
and virtual channel identifier (VCI).
Note: You must use the Setup Wizard to select the correct country for the default ADSL
settings to work.
If your ISP provided you with a multiplexing method or VPI/VCI number, then enter the setting:
1. From the main menu, select ADSL Settings.
2. In the Multiplexing Method drop-down list, select LLC-based or VC-based.
3. For the VPI, type a number between 0 and 255. The default is 8.
4. For the VCI, type a number between 32 and 65535. The default is 35.
5. Click Apply.
How the Internet Connection Works
Your modem router is now configured to p rovide Internet access for your network. Your modem
router automatically connects to the Internet when one of your computers requires access. It is not
necessary to run a dialer or login application such as dial-up networking or Enternet to connect,
log in, or disconnect. The modem router performs these functions automatically as needed.
To access the Internet from any computer connected to your modem router, launch an Internet
browser such as Microsoft Internet Explorer or Netscape Navigator. You should see the modem
router’s Internet LED blink, indicating communication to the ISP. The browser should begin to
display a Web page.

Chapter 2
Wireless Configuration
This chapter describes how to configure the wireless features of your DG834N RangeMaxTM
NEXT Wireless ADSL2+ Modem Router.This chapter includes:
• “Considerations for a Wireless Network”
• “Understanding Wireless Settings”
• “Understanding Wireless Security”
Considerations for a Wireless Network
In planning your wireless network, you should consider the level of security required. You should
also select the physical placement of your modem router to maximize the network speed. For
further information, see the online documentation that you can access from “TCP/IP Networking
Basics” in Appendix B.
To ensure proper compliance and compatibility between similar products in your area, the
operating channel and region must be set correctly.
Observe Performance, Placement, and Range Guidelines
The operating distance or range of your wireless connection can vary significantly bas ed on the
physical placement of the wireless firewall. The latency, data throughput performance, and
notebook power consumption also vary depending on your configuration choices.
Note: Failure to follow these guidelines can result in significant performance degradation
or inability to wirelessly connect to the router. For complete range and
performance specifications, see Appendix A, “Technical Specifications.
For best results, place your firewall:
• Near the center of the area in which your computers will operate
• In an elevated location such as a high shelf where the wirelessly connected computers have
line-of-sight access (even if through walls)

• Away from sources of interference, such as computers, microwaves, and cordless phones
• Away from large metal surfaces
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. Wired Equivalent Privacy (WEP) connections can take slightly longer to
establish. Also, WEP encryption can consume more battery power on a note book computer.
Implement Appropriate Wireless Security
Note: Indoors, computers can connect over wireless networks at a range of several
hundred feet. Such distances can allow for others outside of your immediate area to
access your network.
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The modem router provides highly effective security features, which are
covered in detail in this chapter. Deploy the security fea tures appropriate to your needs.

v1.0, April 2008
DG834N RangeMax NEXT Wireless ADSL2+ Modem Router Reference Manual
There are several ways you can enhance the security of your wireless network:
• Restrict access based on MAC address. You can allow only trusted PCs to connect so that
unknown PCs cannot wirelessly connect to the modem router. Restricting access by MAC
address adds an obstacle against unwanted access to your network, but the data broadcast over
the wireless link is fully exposed.
• Turn off the broadcast of the wireless network name SSID. If you disable broadcast of the
SSID, only devices that have the correct SSID can connect. This nullifies wireless network
discovery feature of some products, such as Windows XP, but the data is still exposed.
• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK, and is
available as an option only if the wireless mode is restricted to 802.11b and 802.11g wireless
stations.
• WPA-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication
implemented using IEE 802.1x and RADIUS servers. This option is available only if the
wireless mode is restricted to 802.11b and 802.11g wireless stations.
• WPA-PSK (TKIP) + WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise.
