Frequently Asked Questions

Question: What can I do if the 22 Mbps Wireless Cable/DSL Router can't obtain an IP address from my Internet Service Porvider (ISP)?

Answer:

  1. Make sure that your broadband modem, analogue modem, or ISDN TA is connected properly.
  2. Try unplugging the power supply of your cable or DSL modem then plugging back it back in to reset it.
  3. If you are using dynamic IP addressing, make sure that your cable or DSL modem supports DHCP pass-through.
  4. Some ISPs require that you use a registered MAC address.
Question: What can I do if the specified installation procedure did not work?

Answer:

  1. Try unplugging the power supply of your cable or DSL modem then plugging back it back in to reset it.
  2. Restore the factory default settings of the 22 Mbps Wireless Cable/DSL Router. Press in and hold the RESET button. While holding the RESET button, unplug then plug back in the power supply. When the 22 Mbps Wireless Cable/DSL Router has power again, continue to hold the RESET button for about five seconds to reset the 22 Mbps Wireless Cable/DSL Router to the factory default settings.

Question: What type of cable do I need to use to connect my broadband modem to the 22 Mbps Wireless Cable/DSL Router?

Answer:

Some types of broadband modems require that you use a cross-over cable to connect to the 22 Mbps Wireless Cable/DSL Router. Use the cables that were included with your 22 Mbps Wireless Cable/DSL Router and with your broadband modem. Contact your ISP if you are still uncertain about which type of 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 22 Mbps Wireless Cable/DSL Router support IPSEC?

Answer:

Yes, the 22 Mbps Wireless Cable/DSL Router supports IPSEC pass-through.

Question: What type of firewall is the 22 Mbps Wireless Cable/DSL Router equipped with?

Answer:

The 22 Mbps Wireless Cable/DSL 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 your computer with a static IP.

Question: If DMZ is used, does the exposed user share the public IP with the 22 Mbps Wireless Cable/DSL Router?

Answer:

No, all specific requests are forwarded to the DMZ host.

Question: What should I do if I am unable to access my e-mail or the Web page of my ISP?

Answer:

You should contact your ISP to get the full URL and then perform the following steps:

  1. Connect your broadband modem directly to one of your computers.
  2. 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.
  3. After you get the IP address, enter the IP address in the mail server option or in the address line of your Web 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: Are PPTP packets passed through or actively routed by the 22 Mbps Wireless Cable/DSL Router?

Answer:

The 22 Mbps Wireless Cable/DSL Router does allow pass-through of PPTP packets.

Question: What is the maximum number of users that the 22 Mbps Wireless Cable/DSL Router will allow?

Answer:

If you attach additional hubs to the 22 Mbps Wireless Cable/DSL Router, up to 253 separate users can connect to the 22 Mbps Wireless Cable/DSL Router.

Question: Is the 22 Mbps Wireless Cable/DSL Router compatible across different platforms?

Answer:

Any platform that supports Ethernet, Wi-Fi compatible 802.11b products, and TCP/IP is compatible with the 22 Mbps Wireless Cable/DSL Router.

Question: Will the 22 Mbps Wireless Cable/DSL Router allow me to use my own public IPs and domain, or do I have to use the IPs provided by the 22 Mbps Wireless Cable/DSL Router?

Answer:

Only one valid Internet IP address is necessary. The internal IP address range will still go through the NAT firewall for all outbound Internet requests. All inbound requests will be blocked unless specific settings have been set up, such as port forwarding or DMZ.

Question: How many ports can be forwarded at the same time?

Answer:

You can forward up to 20 ports at the same time.

Question: Can the 22 Mbps Wireless Cable/DSL Router be used in place of a modem?

Answer:

No, the 22 Mbps Wireless Cable/DSL Router must be used with a broadband modem, an analogue modem, or an ISDN TA.

Question: Is there a security log feature for the 22 Mbps Wireless Cable/DSL Router?

Answer:

Yes, there is a security log feature in the Tools page of the Configuration Utility.
