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
notebook to the cable.
• Click Start, Control Panel, Network and Internet Connections, Network Connections.
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).
• Use the networking problems troubleshooter in Windows Help and Support.
• Click Start, Control Panel, Performance and Maintenance, System. On the Hardware
tab, open the Device Manager. If the network interface is disabled, try to enable it. If
it has a conflict, try disabling another device.
If you can't browse My Network Places
• Click Start, Search to look for a computer.
• Check with your network administrator to make sure NetBEUI protocol is supported
on the network.
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 notebook 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 file transfers are unusually slow or produce timeout errors
• Connect the AC adapter.
• Use the BIOS configuration utility to set I/O Performance to Max I/O Performance—
see "To run the BIOS configuration utility" on page 102. (This significantly reduces
