17.The Power LED keeps flashing.

The Power LED flashes when the device is first powered up. Meantime, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED stays solid to show that the system is working fine. If the LED keeps flashing after this time, the device is not working properly. Try to flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using the following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0.

18.When I enter a URL or IP address, I get a time-out error or am prompted to retry.

•Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address, Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.

•If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)

•If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is working correctly. You can remove the Router to verify a direct connection.

•Manually configure the TCP/IP settings with a DNS address provided by your ISP.

•Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet.

Frequently Asked Questions

What is the maximum number of IP addresses that the Router will support?

The Router will support up to 253 IP addresses.

Is IPSec Pass-Through supported by the Router?

Yes, it is a built-in feature that the Router automatically enables.

Where is the Router installed on the network?

In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into the cable/DSL modem’s Ethernet port.

Does the Router support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but those protocols cannot connect from the Internet to a LAN.

WRT54G specifications

The Cisco Systems WRT54G is a cornerstone of home and small office networking, renowned for its robust features and reliability since its release in 2002. Widely acknowledged as one of the first consumer-grade routers to combine wireless and wired networking capabilities, the WRT54G has earned a legacy as a hallmark of simplicity and performance.

At the heart of its functionality is the 802.11g wireless standard, which allows for wireless connections at speeds of up to 54 Mbps. This technology ensures a reliable connection over significant distances, making it suitable for various home and office environments. The WRT54G operates on the 2.4 GHz frequency band, which provides compatibility with many devices but can be susceptible to interference from other electronic devices.

One of the standout features of the WRT54G is its user-friendly web interface, allowing even non-technical users to easily configure their network settings. This feature promotes security by enabling users to modify their network name, set up encryption protocols like WEP or WPA, and create a guest network for visitors. The router also incorporates a built-in firewall and supports Network Address Translation (NAT), adding an additional layer of security to users’ private networks.

The WRT54G boasts four Ethernet ports for wired connections, accommodating multiple devices simultaneously. This feature is particularly beneficial for users with desktop computers, gaming consoles, or network-attached storage devices requiring stable, high-speed connections. The ability to connect devices through Ethernet ensures that users can enjoy the benefits of a reliable and fast network, especially in environments where wireless connectivity may be limited.

Another distinguishing characteristic of the WRT54G is its open-source firmware capability, which has led to a devoted community of enthusiasts who have developed alternative firmware for greater customization and advanced features. This flexibility not only enhances the router's lifespan but also caters to users who require specific functionalities, such as advanced Quality of Service (QoS) settings or more extensive parental controls.

In conclusion, the Cisco Systems WRT54G remains a significant player in the realm of consumer networking due to its innovative features, ease of use, and adaptability. While newer models have since emerged, the WRT54G's enduring reputation speaks to its reliability and solid performance, making it a preferred choice for many users seeking to establish a dependable network.
