Changing Adapter Settings with PROSet™
There are two ways to run PROSet which allows changing the
adapter settings.
l From the Control Panel, double-click on the [PROSet] icon.
l From the Control Panel, double-click on the [Network] icon,
select the Adapters tab, and double-click on the "Intel(R)
PRO/100+ PCI Adapter".
From the main PROSet menu, you can click the Advanced tab to
view and modify adapter settings. The defaults work correctly for
most configurations. The following table lists the PROSet
parameters that can be configured in the Advanced menu.
PROSet
Parameter
Description
Speed
Recommended
Setting
[Auto Detect]
(default)
This parameter lets the PRO/100+ adapter know what speed to use on the Ethernet
connection. The choices are 10 Mbps, 100 Mbps, and Auto Detect.
In Auto Detect mode, the adapter detects if its networking environment can support 100
Mbps speed. It then sets the speed to 100Mbps if so, or otherwise to 10Mbps.
Note: If you want to choose a Duplex Mode other than Auto Detect, you must set the
speed to either 10 Mbps or 100 Mbps.
Duplex
Recommended
Setting
[Auto Detect]
Auto Detect
Auto Detect: The adapter negotiates with the hub or switch how to send/ receive
packets, either full or half duplex.
Full-Duplex: The adapter sends and receives packets at the same time. This improves
the performance of your adapter. Set duplex mode to full duplex only if you have a switch
that also supports full duplex.
Half-Duplex: The adapter performs one operation at a time. It either sends or receives.
Note: In order to allow changing the Duplex mode, you must set the Speed to either 10
Mbps or 100 Mbps.
The PRO/100+ adapter has the ability to send and receive packets at the same time
(full-duplexing) at both 10 and 100 Mbps. In order to reap the benefits of full duplexing,
you MUST have a full duplex hub or switch.
The PRO/100+ adapter has the added ability to "talk" to the hub or switch and determine
at which mode to communicate (either full or half duplex). This is called auto-
negotiation. You must have an auto-negotiating hub or switch to get full duplex support
with the Duplex Mode set to Auto. If you don't have an auto-negotiating hub or switch
and want to run at full duplex, set Duplex Mode to Full and then set the SPEED
parameter to either 100 Mbps or 10 Mbps.
The PRO/100B T4 adapter can not operate in full duplex mode at 100 Mbps.
The PRO/10+ PCI adapter can only operate in full duplex mode at 10 Mbps and only on
the TPE connector. The PRO/10+ PCI adapter does not support auto-negotiation; it will
run at half duplex unless forced.
