Frequently Asked Questions
Question: What can I do if the Broadband Router can't obtain an IP address from my ISP?Answer:
- Make sure that your cable or DSL modem is connected properly.
- Try unplugging then plugging back in your cable or DSL modem in order to reset it.
- If you are using dynamic IP addressing, make sure that your cable or DSL modem is DHCP-capable.
- Some ISPs require that you use a registered MAC address.
Answer:
- Try unplugging then plugging in your cable or DSL modem in order to reset it.
- Unplug the power supply. Press in and hold the RESET button. While holding the RESET button, plug in the power supply. When the Broadband Router has power again, continue to hold the RESET button until the SYSTEM LED begins flashing. This will reset the Broadband Router to the factory default settings.
Question: What type of Ethernet cable do I need to use to connect my cable modem or DSL modem to the Broadband Router?
Answer:
Some types of cable modems and DSL modems require that you use a cross-over Ethernet cable to connect to the Broadband Router. Use the Ethernet cables that were included with your Broadband Router and with your modem. Contact your ISP if you are still uncertain about which type of Ethernet cable you must use.
Question: How do I access the Configuration Utility?
Answer:
Launch your Internet browser and enter the default IP address, http://192.168.123.254.
Question: Does the Broadband Router support IPSec or PPTP?Answer:
The Broadband Router supports IPSEC and PPTP pass-through.
Question: What type of firewall is the Broadband Router equipped with?Answer:
The Broadband Router uses NAT and TCP/IP port inspections.
Question: What is NAT?
Answer:
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This provides security since the IP address of a computer on the LAN is not transmitted to the Internet. The user can have multiple private addresses behind the single address that was provided by the ISP.
Question: What is DMZ?
Answer:
DMZ stands for Demilitarized Zone. This feature allows one IP Address to be exposed to the Internet. DMZ allows only one computer to be exposed when multiple TCP/IP ports need to be open. If you want to use DMZ, you must set computer with a static IP.
Question: If DMZ is used, does the exposed user share the public IP with the Broadband Router?Answer:
No, all specific requests are forwarded to the DMZ host.
Question: What should I do if I am unable to access my email or the Web page of my ISP?Answer:
You should contact your ISP to get the full URL and then perform the
following steps:
- Connect your cable modem or DSL modem directly to one of your computers.
- Perform the ping command by clicking Windows Start and then Run. In the Run dialog box, Windows 95, 98, and Me users should type command. Windows 2000, NT, and XP users should type cmd. All users should then enter the following command: ping xxx, where xxx is the complete URL for your ISP.
- After you get the IP Address, enter the IP address on the mail server option or the Internet browser.
Question: Why can't I access the Configuration Utility?
Answer:
You may have to remove the proxy settings or the dial-up settings on your Internet browser.
Question: What is the maximum number of users that the Broadband Router will allow?Answer:
If you attach additional hubs to the Broadband Router, up to 253 separate users can connect to the Broadband Router.
Question: Is the Broadband Router compatible across different platforms?
Answer:
Any platform that supports Ethernet & TCP/IP is compatible with the Broadband Router.
Question: Will the Broadband Router allow you to use your own public IPs and Domain or do you have to use the IPs provided by the Broadband Router?Answer:
The Broadband Router mode allows for customization of your public IPs and Domain.
Question: How many ports can be forwarded at the same time?Answer:
You can forward 20 ports at the same time.
Question: Can the Broadband Router be used in place of a modem?Answer:
No, the Broadband Router must be used with a cable modem or DSL modem.
Question: What are the Advanced Settings?
Answer:
The advanced features of the Broadband Router include Firewall, NAT, Special Application, Virtual DMZ Host, Remote Management, and Client Filtering.
Question: Is there a security log feature for the Broadband Router?
Answer:
Yes, there is a security log feature in the Status page of the Configuration Utility.
Question: Does the Broadband Router support Universal Plug and Play (UPnP)?
Answer:
Yes, the USR8003 Broadband Router does supports UPnP.
Question: What is UPnP?
Answer:
Universal Plug and Play (UPnP) is a network feature utilizing the Internet and Web protocols to promote the communicative exchange of information between networking devices. In other words, with UPnP, when a user plugs a device into a network (such as a printer), the device will self-configure by acquiring a TCP/IP address, and use a discovery protocol based on the Internet’s Hypertext Transfer Protocol (HTTP) to relay its presence and availability to all other networking devices connected to the network.
Question: What are the benefits of UPnP?
Answer:
Simplicity, interoperability, and choices. Networking products that include Universal Plug and Play technology will "just plain work" when physically connected to the network. UPnP can work with essentially any networking media technology, wired or wireless.
There is little doubt that the primary objective of UPnP is to provide home networks, proximity networks, and networks in small buildings the ability to enable data communication between any two devices through the command of any control device on the network. This is significant since in essence, the use of UPnP affords the end user the virtual ability to add more networking bandwidth without adding the extra work of setting it up in the first place. Taking advantage of this technology for data communication is only limited by the user's imagination. With UPnP, and a few extra peripherals, a user can regulate a thermostat, synchronize household clocks, even monitor the security activity of a house or business through the use of cameras and a UPnP-enabled TV.
In addition, UPnP is independent of any particular operating system, programming language, or physical medium. This is equally significant since a device can also leave a network smoothly, automatically, and efficiently without leaving any residual or unwanted state behind. Finally, UPnP is a self-sufficient learning tool that benefits its users by learning from the Internet’s success, leveraging all of its more significant components to work together using the same language. What this means is that UPnP, in use with the combined efforts of a multi-vendor collaboration for establishing standard Device Control Protocols (DCPs), has established contracts between all wire protocols such as IP, TCP, UDP, HTTP, and XML. As such, UPnP expresses declarative language in XML and communicates this language via HTTP.
Question: How do I install Universal Plug and Play?
Answer:
Note: UPnP is currently supported in Windows Me and Windows XP only.
Note: To open Add or Remove Programs, click Windows Start, Control Panel, and then click Add or Remove Programs.
- Open Add or Remove Programs in Control Panel.
- Click Add/Remove Windows Components.
- In the Components list, select the Networking Services check box, and click Details.
- Make sure the Universal Plug and Play check box is selected.
Question: What software supports UPnP?
Answer:
UPnP is supported in Windows Me and Windows XP only. Microsoft’s Remote Assistance, Remote Desktop, and MSN Messenger Version 5.0 are examples of supported software titles.
