Common Problems and Solutions

In addition to the table below, review the product release notes.

Problem

Solution

Your computer cannot find the adapter

  • Make sure the adapter is seated firmly in the slot.

  • Download the latest drivers from the Intel support web site: http://www.intel.com/network

  • Try a different PCI bus master slot. 

  • Check to see if your motherboard has the latest BIOS.

  • Make sure your PCI slots are v2.2 compatible. 

  • Try rebooting the computer.

  • Try a different Intel adapter.

Diagnostics pass but the connection fails

  • Check the responding link partner.

  • Make sure the cable is securely attached, is the proper type and does not exceed the recommended lengths. 

  • Try another cable.

  • Try running the Sender-Responder diagnostic Test.

  • Make sure the duplex mode and speed setting on the adapter matches the setting on the switch.

Another adapter stops working after you installed the Intel PRO/1000 adapter

  • Make sure the cable connections are correct.

  • Make sure your PCI BIOS is current. See PCI Installation Tips.

  • Check for interrupt conflicts and sharing problems. Make sure the other adapter supports shared interrupts. Also, make sure your operating system supports shared interrupts.

  • Unload all PCI device drivers, then reload all drivers.

  • Try reseating all adapters.

Adapter unable to connect to switch at 1000 Mbps, instead connects at 100 Mbps 

This is applicable only to copper-based connections. 

  • Try another cable.

  • Make sure the link partner is set to auto-negotiate.  

  • Verify that switch is IEEE 802.3ab-compliant (gigabit over copper) and that you are running the latest operating system revision for your switch. 

The adapter stops working without apparent cause

  • The network driver files may be damaged or deleted. Reinstall the drivers.

  • Try reseating the adapter in its slot or different slot, if necessary.

  • Try rebooting the computer.

  • Try another cable.

  • Try a different adapter.

  • Run the adapter and network tests described under "Test the Adapter".

The Link indicator light is off

  • Run the adapter and network tests described under "Test the Adapter".

  • Make sure you loaded the adapter driver.

  • Check all connections at the adapter and the switch.

  • Try another port on the switch.

  • Make sure the cable is securely attached. Also make sure that it is the proper type and does not exceed the recommended lengths. 

  • Make sure that the link partner is configured to auto-negotiate (or forced to match adapter).

  • Verify that the switch is IEEE 802.3ab-compliant.

The link light is on, but communications are not properly established
  • Make sure the proper (and latest) driver is loaded. 

  • Both the adapter and its link partner must be set to either auto-detect or manually set to the same speed and duplex settings.  

The adapter's link indicator light may be on even if communications between the adapter and its link partner have not been properly established. Technically, the link indicator light represents the presence of a carrier signal but not necessarily the ability to properly communicate with a link partner.  This is expected behavior and is consistent with IEEE's specification for physical layer operation.

RX or TX light is off
  • Make sure you've loaded the network drivers.

  • Network may be idle; try creating traffic while monitoring the lights.

  • Try another adapter.

The diagnostic utility reports the adapter is "Not enabled by BIOS"
The computer hangs when the drivers are loaded

Try changing the PCI BIOS interrupt settings. See PCI Installation Tips.

Event viewer message: A device attached to the system is not functioning

If there is a BIOS setting for "Plug and Play OS", it should be set to "NO" for all versions of Windows*. 

Install prompting for Prodd.vxd and Prokddp.vxd files in Windows 2000
If you use the Add/Remove Programs icon in the Windows Control Panel to remove an Intel adapter, and then try to install drivers from a later Intel CD, you may see a prompt asking for the following files:
"Prodd.vxd"
"Prokddp.vxd"

This is because Windows is attempting to install the files associated with the earlier driver, which are not present on the later Intel CD.

To resolve this problem, finish the installation and choose "Skip" when prompted for a missing file. Then, instead of removing the driver, update it with the later Intel CD.

For instructions on updating the adapter driver, see the "Install the Network Drivers" section in this online guide. 

Windows 2000, Windows XP, or Windows Server 2003: Unable to remove PROSet in SAFE mode If you experience computer hangs (blue screens) after configuring network adapters with the Intel® PROSet utility, try the following:
  1. Start Windows in Safe mode

  2. Go to the Intel PROSet utility, and disable the network adapters and teams.

  3. Restart the computer.

  4. Windows should be operating normally if the problem was caused by the disabled adapters. If Windows is not operating normally, discontinue the instructions in this section and troubleshoot Windows using the troubleshooting tools offered by your operating system.

  5. If Windows is operating normally, uninstall Intel PROSet and then reinstall it. To do this, follow the steps below.

  1. Start Windows in Safe mode.

  2. Use Intel PROSet to disable all teaming instances, if any.

  3. Restart the computer in Normal mode.

  4. Using Intel PROSet, remove all teams and VLANs shown.

  5. Go to the Control Panel, select Add/Remove Programs.

  6. Select Intel PROSet and remove it.

  7. Reinstall Intel PROSet by inserting the Intel CD and clicking Install Software.

Windows XP or Windows Server 2003 gives an error "Device cannot start (CODE 10)" when you install or update drivers for your gigabit adapter.  Windows XP and Windows Server 2003 ship with some older plug-and-play drivers for gigabit adapters already present. Because XP has trouble replacing a driver file on-the-fly, updating these drivers with Intel's latest drivers may cause this error message. Rebooting your computer will clear the error and allow you to use the full functionality of your adapter. 
After upgrading operating systems, Intel PROSet is no longer available If you are upgrading Windows operating systems and you have Intel PROSet software installed, it will be deleted in the process. You will need to reinstall Intel PROSet.
In Windows XP or Windows Server 2003, IP addresses are lost or Intel PROSet becomes unstable with bridging enabled With bridging enabled, Intel PROSet does not retain adapter IP address information.

If changes are made to any Intel PROSet advanced feature after enabling bridging, the Intel PROSet software becomes unstable.
Terminal Server support When using Terminal Server, make sure only one session of Intel PROSet is open at any one time. Simultaneous sessions are not supported in Intel PROSet.

The IPv6 protocol does not seem to work after updating adapter drivers on Windows 2000 Advanced Servers.

When using a Windows 2000 Advanced Server SP1 with IPv6 bound to the adapter, you must unbind the IPv6 protocol from the adapter before updating drivers. This is a result of the operating system implementation of the IPv6 protocol. To update an adapter using the IPv6 protocol:

  1. Unbind the IPv6 protocol from the adapter. To find the IPv6 setting, click Start > Settings > Control Panel > Network and Dial-Up connectionsLocal Area Connection <#>, where <#> is the connection number. Right-click the Connection number to open the Adapter Properties dialog box. Clear the IPv6 checkbox then click OK.

  2. Update drivers. 

  3. Bind the IPv6 protocol to the adapter. In the Adapter Properties dialog box, click the IPv6 checkbox. See step one for detailed instructions on finding the IPv6 option.


Other Items to Check

If none of these works, check the Late-breaking News document that came with the adapter or check the Intel support Web site. See Intel Customer Support for information on connecting to Intel's online services.


Multiple Adapters

When configuring a multi-adapter environment, you must upgrade all Intel adapters in the computer to the latest software.

If the computer has trouble detecting all adapters, consider the following:


PCI and PCI-X Configuration Troubleshooting

If the adapter is not recognized by your OS or if it does not work you may need to change some BIOS Setup program settings. Try the following only if you are having problems with the adapter. 

Here are some examples of BIOS Setup program parameters:

PCI slot #: Slot where the adapter is installed (1-3)
Master: ENABLED
Slave: ENABLED
Latency timer: 40 - 80
Interrupt: Choose any one of several that the BIOS Setup provides.
Edge-level: Level

The exact wording of the parameters varies with different computers.


Other Performance Issues

Attaining gigabit speeds requires that many components are operating at peak efficiency. Among them are the following:

NOTE: On NT4.0 computers, some applications may cause incorrect behavior and even blue screen at deserialized drivers. This is an operating system bug admitted by Microsoft that currently won't be fixed in NT 4.0. This bug was fixed for Windows 2000 and later. Intel's base drivers are not affected.
