LAN problems

If the built-in network adapter doesn't connect to the LAN
• Check all cables and connections. Try connecting at a different network station, if
available.
• If the green light next to the LAN port does not light, the LAN cable may not be
connected to the network or the network may be down. Try connecting a different
computer to the cable.
• For Windows 98, open Network in Control Panel. Make sure you have the correct
clients and protocols installed.
• Make sure the LAN cable is Category 3, 4, or 5 for 10Base-T operation, or Category
5 for 100Base-TX operation. Maximum cable length is 100 meters (330 feet).
• Click Start, Help (or Help and Support), and use the Networking troubleshooter.
• Open the hardware Device Manager: click Start, Settings, Control Panel, System
(Windows 98 or 2000) or Start, Control Panel, Performance and Maintenance, System
(Windows XP). If the network interface is disabled, try to enable it. If it has a conflict,
try disabling another device.
If you can't browse the Network Neighborhood or My Network Places
• Check with your network administrator to make sure NetBEUI protocol is supported
on the network.
• Click Start, Find, Find Computer (Windows 98 or 2000) or Start, Search, Computers
or People (Windows XP) to look for a computer.
If you can't log in to Netware servers
• If a Netware server is using IPX/SPX protocol, you may need to force your frame
type to match the server's frame type. Check with your network administrator.
If the computer stops responding after booting
• Check whether you have a TCP/IP network with no DHCP server. This can cause a
long delay at startup because DHCP is enabled. Contact your network administrator
to determine the proper TCP/IP configuration.
If you have slow or dropped connections on a 10/100 network switch or hub
• The switch may be forced to 10 Mbps. For Windows 98, use Network in Control
Panel to disable Auto Polarity for the network adapter.
