NOTES:
l Although some adapter property sheets (driver property settings) list 10 Mbps and 100 Mbps
in full or half duplex as options, using those settings is not recommended.
l Only experienced network administrators should force speed and duplex manually.
l You cannot change the speed or duplex of Intel adapters that use fiber cabling.
Intel 10 Gigabit adapters that support 1 gigabit speed allow you to configure the speed setting. If this option is
not present, your adapter only runs at its native speed.
If the adapter cannot establish link with the gigabit link partner using auto-negotiation, set the adapter to 1
Gbps Full duplex.
Intel 10 gigabit fiber-based adapters and SFP direct-attach devices operate only in full duplex, and only at their
native speed. Multi-speed 10 gigabit SFP+ fiber modules support full duplex at 10 Gbps and 1 Gbps.
Auto-negotiation and Auto-Try are not supported on devices based on the Intel® Ethernet Connection X552
controller and Intel® Ethernet Connection X553 controller.
Manually Configuring Duplex and Speed Settings
Configuration is specific to your operating system driver. To set a specific Link Speed and Duplex mode, refer
to the section below that corresponds to your operating system.
CAUTION: The settings at the switch must always match the adapter settings. Adapter per-
formance may suffer, or your adapter might not operate correctly if you configure the adapter
differently from your switch.
The default setting is for auto-negotiation to be enabled. Only change this setting to match your link partner's
speed and duplex setting if you are having trouble connecting.
1. In Windows Device Manager, double-click the adapter you want to configure.
2. On the Link Speed tab, select a speed and duplex option from the Speed and Duplex drop-down
menu.
3. Click OK.
More specific instructions are available in the Intel PROSet help.
Advanced Tab
The settings listed on Intel PROSet for Windows Device Manager's Advanced tab allow you to customize
how the adapter handles QoS packet tagging, Jumbo Packets, Offloading, and other capabilities. Some of the
following features might not be available depending on the operating system you are running, the specific
adapters installed, and the specific platform you are using.
Adaptive Inter-Frame Spacing
Compensates for excessive Ethernet packet collisions on the network.
The default setting works best for most computers and networks. By enabling this feature, the network
adapter dynamically adapts to the network traffic conditions. However, in some rare cases you might obtain
better performance by disabling this feature. This setting forces a static gap between packets.
