Disabling the
Autosensing
Capabilities
Your computer automatically senses if the attached network
supports 10Mbs or 100Mbs and configures itself accordingly.
This process of determining the maximum network operating
speed is known as autosensing. The computer begins
autosensing whenever it loses a valid network link, for example,
if the cable is disconnected.
In addition to determining the network operating speed, the
computer determined if full-duplex is supported. Full-duplex
systems can transmit and receive information on the network
simultaneously. Half-duplex systems cannot transmit and
receive simultaneously. The different modes of operation are:
■
100Base-TX, full-duplex
■
100Base-TX, half-duplex
■
10Base-T, full-duplex
■
10Base-T, half-duplex
If necessary, you can disable the autosensing capabilities and
force the system into the correct operating mode. To set the
network operating mode manually, complete the following
steps:
1. Double-click the Network icon, located in the Control
Panel.
2. Double-click the Compaq Netelligent 10/100 TX
Embedded UTP Controller.
3. Select the Advanced Properties tab.
4. Select Media Speed and change the value from AUTO to
10Mbs or 100Mbs, depending on the capabilities of your
network.
5. Select Duplex Settings and change the value from AUTO
to Full or Half, depending on the capabilities of your
network.
6. Exit the Network control application.
You will be prompted to restart your computer in order for
the changes to take affect.
