STEP 2. OPTIMIZING YOUR COMPUTER

Before you can configure the LAN Modem for Internet access, each computer must be properly set up with TCP/IP and optimized for use with the LAN Modem. Follow the instructions below for your operating system.

If you already know that you will be connecting to a static IP network, the EZ-LAN Wizard can attempt to optimize your network settings to allow you to access the initial LAN Modem configuration screens. If you have difficulty, or if you prefer to follow a more detailed manual procedure, refer to the instructions in

Chapter 3 of the User Guide instead of running the EZ-LAN Wizard.

Windows 95, 98, 2000 and NT: Run the EZ-LAN Wizard from the OfficeConnect Dual 56K Companion Programs CD-ROM. EZ-LAN checks the settings on your computer and, if you choose, optimizes them for use with the LAN Modem. Be sure to run the EZ-LAN Wizard on all PCs that you plan to network.

Macintosh: Perform this simple check to verify that the settings on your computer or computers are optimized for use with the LAN Modem:

1From the Apple menu, select Control Panels, and then TCP/IP.

2In the Connect Via field, select Ethernet (if iMac, select Ethernet built-in).

3Look at the Configure field entry.

If it is set to Using DHCP Server and all other fields are blank or set to <will be supplied by server>, then you are ready to continue directly with Step 2, “Installing the LAN Modem.”

If Configure is set to anything other than Using DHCP Server (there are specific values in any of the other fields), your com- puter may have a static IP address. Refer to Chapter 3 of the User Guide to perform additional steps not covered in this Getting Started Guide.

3C888 specifications

The 3Com 3C888 is a versatile networking device that was part of the company's innovative range of network interface cards (NICs) aimed at enhancing computer connectivity. These devices were integral to the evolution of networking in both consumer and enterprise environments during the late 1990s and early 2000s.

One of the standout features of the 3C888 is its dual functionality. It combines both Ethernet and Token Ring capabilities, allowing users to connect to different network types without needing separate cards. This integration made it a particularly attractive option for businesses transitioning from Token Ring to Ethernet networks, as it provided a seamless upgrade path.

The 3C888 utilizes a PCI interface, which offers a wide bandwidth that significantly reduces latency compared to its predecessors. This technological advancement ensures fast and reliable data transfer rates, making it suitable for data-intensive applications. The card also supports a 10/100 Mbps auto-sensing feature, enabling it to adapt to varying network speeds without the need for manual configuration.

Additionally, the card included built-in memory and processing capabilities, allowing it to offload network processing tasks from the main CPU. This feature reduced the overall system load and improved the performance of other applications running on the host machine.

In terms of compatibility, the 3C888 was designed to work with multiple operating systems, including Windows, Linux, and various network protocols. This level of compatibility made it an easy choice for IT departments that managed heterogeneous computing environments.

Another defining characteristic of the 3C888 is its robust diagnostic capabilities. The card comes equipped with advanced tools that facilitate troubleshooting and network monitoring. These tools help network administrators quickly identify and resolve connectivity issues, minimizing downtime and enhancing overall productivity.

Security features were also a key consideration in the design of the 3C888. It supported various encryption protocols, providing secure data transmission over networks, which was crucial during an era when data breaches were beginning to attract significant attention.

In summary, the 3Com 3C888 stands out as a pioneering device that combines multiple networking standards, advanced processing capabilities, and robust security features. Its design not only facilitated the transition between network technologies but also played a crucial role in the growth of enterprise networking solutions during its time. With its blend of features and reliability, the 3C888 has left a lasting mark in the history of networking devices.
