If you have network problems, perform the following steps:
1. Check the two status indicators on the computer’s back panel for activity.
‡
The green indicator lights when the system is connected to a 100–megabit-
per-second (Mbps) network.
‡
The yellow indicator flashes brightly when activity occurs on either a 100- or
10-Mbps network connection. The green indicator turns off when the system
is connected to a 10-Mbps network.
NOTE: If you can connect to the network but are having problems accessing
network resources, contact your network administrator.
2. Check the network connections.
a. Check the network connector for physical damage.
b. Ensure that both ends of the network cable are inserted properly.
Press one end of the unshielded twisted pair (UTP) Ethernet cable into the
network connector until the cable snaps securely into place. Connect the
other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a UTP
concentrator or hub, depending on your network configuration.
c. Replace the patch cable or network cable from the wall jack to the computer.
d. If replacing the patch cable or network cable does not solve the problem, try
moving the computer to a known working location on the network.
3. Reinstall the network drivers that came with your system (see “Network Drivers”
in Chapter 5).
