PTIMIZING 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:
1 From the Apple menu, select Control Panels, and then TCP/IP .
2 In the Connect Via field, select Ethernet (if iMac, select Ethernet built-in).
3 Look 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.
