Common Problems and Solutions

1.I need to set a static IP address on a computer.

You can assign a static IP address to a computer by performing the following steps:

•For Windows 98 and Me:

1.Click Start, Settings, and Control Panel. Double-click Network.

2.In The following network components are installed box, select the TCP/IP-> associated with your Ethernet Adapter. If you only have one Ethernet Adapter installed, you will only see one TCP/IP line with no association to an Ethernet Adapter. Highlight it and click the Properties button.

3.In the TCP/IP properties window, select the IP address tab, and select Specify an IP address. Enter a unique IP address that is not used by any other computer on the network connected to the Gateway. Make sure that each IP address is unique for each computer or network device.

4.Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1, which is the default IP address of the Gateway. Click the Add button to accept the entry.

5.Click the DNS tab, and make sure the DNS Enabled option is selected. Enter the Host and Domain names (e.g., John for Host and home for Domain). Enter the DNS entry provided by your ISP. If your ISP has not provided the DNS IP address, contact your ISP to get that information or go to its website for the information.

6.Click the OK button in the TCP/IP properties window, and click Close or the OK button for the Network window.

7.Restart the computer when asked.
