Wired Ethernet

Intel has a long history of delivering quality Ethernet products. Back in 1980, Intel teamed up with DEC* and Xerox* to publish the first Ethernet specification called DIX. The specs were later adopted by IEEE in 1982. So, Intel has been in the Ethernet business for 30 years!


Intel’s expertise in Ethernet includes a long line of Ethernet silicon and adapters. Early on, we branded our adapters with “PRO” as part of the name. The earliest use I could find of the “PRO” brand name dates back to the EtherExpress™ PRO/10 ISA adapters. The “PRO” name carried forward to many popular Intel® PRO/100 fast Ethernet and PRO/1000 gigabit Ethernet devices.


The Intel® PRO/1000 PT Quad Port Low Profile Server Adapter, which debuted in 2006, was the industry’s first low-profile quad-port NIC and the last to use “PRO” in the name. But the Intel® PRO/1000 PT Quad Port Low Profile Server Adapter was not the end of the line.


Building on our experience with both Ethernet and silicon, we continued to improve our designs. Even though the brand names no longer include “PRO” as part of the name, the newest adapters still have the same “PRO” quality and dependability, only better. The innovation has continued and includes the industry’s first integrated quad port controller with new features like virtualization.


So, if you are looking for the very latest, full-featured Intel® PRO/1000 adapters, you should be looking at the Intel® Ethernet I350 Server Adapter Family.

And for 10-Gigabit Ethernet you will want to check out our latest Converged Network adapters for the best solutions supporting unified networking. For familiar twisted-pair copper cable support that includes backwards compatibility with gigabit Ethernet, check out the Intel® Ethernet X540 Converged Network Adapter. For SFP+ solutions including direct-attach copper, short-range, and long-range support, check out the Intel® Ethernet X520 Converged Network Adapter Family.

Several drivers and software updates were combined in version 16.4 of Intel® Network Connections software. Many of you posted information in the discussion threads that helped us identify the bugs. Thank you for the information and your patience.


Searching the Intel Download Center  for “16.4 Network” will find most of the files. Add your OS, (e.g. Windows 7) to the search to narrow the results.

The long awaited e1q driver fixes are available in version 16.4. Some of the issues that were discussed in the communities include:

  • Blue screen of death in Windows* 7 on Intel® 82583V Gigabit Network Connection 
  • Dropped video packets during multicast on Intel® 82574L Gigabit Network Connection
  • Blue screen of death during Hyper-V cluster failover when VMQ is enabled on Intel® Gigabit ET, ET2, and EF Multi-Port Server Adapters
  • Communications lost when VMQ is enabled on teams of Intel® Gigabit ET, ET2, and EF Multi-Port Server Adapters


Besides the e1q drivers mentioned above, the e1c, ixn and e1e Windows* drivers and Linux* drivers, e1000e, ixgbe and igb were updated along with improvements to Intel® PROSet for Windows Device Manager and the ANS software used for VLANs and teaming.


I should also mention that the authors of the User Guides work hard to improve the guides and keep them up to date. Almost every software release has User Guide updates, and the version 16.4 release is no exception.


Thank you for using Intel® Ethernet.



In 2009, Intel started adding code verification labels to some Intel® Ethernet adapters. Today, nearly every Intel Ethernet adapter sold comes with the label. The blue holographic background to the number codes makes the label hard to miss.


Here is an example of a code verification label.

But what does this label mean to you?

You can use the code to verify that your Intel® Ethernet adapter is genuine. The code on each adapter is unique and can be matched to other information about the adapter. Verification is quick and easy.


  1. Browse to verify.
  2. Enter the verification code and click Trace.
  3. Check that the results match your adapter.

If everything matches, then you have a genuine Intel Ethernet adapter. Finished!

If you are wondering where to find the Mac Address and PBA number, they can be found in the serial number on the component side of the Intel Ethernet adapter. The first set of numbers is the Mac address and the last set of numbers is the PBA number.

What’s in the box?

Posted by mark_h_@intel Mar 8, 2011

If you haven’t bought a plug-in Intel® Ethernet adapter recently, you might wonder just what you can expect to find when you open the box.  Now you can watch while my co-worker Rich opens the box of an Intel® Ethernet Server Adapter X520-DA2.



As you can see, along with an Ethernet adapter you can count on, you get the brackets needed to install the adapter in either a full-height or half-height slot and a CD with the software, drivers, and manuals you need.


Just as important are the things you get with an Intel® Ethernet adapter that you cannot hold in your hand. With Intel® Ethernet adapters you get performance and reliability backed by more than 25 years of network connectivity experience and Intel worldwide customer support.


What you get is what you expect. Once you finish with the installation and plug in the Ethernet cable, it just works!

You may have noticed community postings about some desktops and laptops with slow connections after waking up, no connection after a driver upgrade, and similar connection issues. Well, we heard you and we now have a new driver release to fix those problems.


Download version 15.2 for driver updates that I expect will work for most of you. The version 15.2 release focuses on the problems you reported in the community.


If the driver update does not work for you, we look forward to hearing from you. If you need help with a connection issue include lots of details when you post. And do not forget to check with the manufacturer of your computer for BIOS or other updates that might affect your Ethernet connection.


Thank you for using Intel® Ethernet and for participating in the Intel communities.

An update to the PXE software that is integrated into the BIOS of some new computers with built-in Intel® Gigabit Network Connections is causing PXE boot to fail with an error: 


PXE-E74 bad or missing pxe menu and or prompt information.


The issue appears when the boot menu sent from the PXE server is long enough to cause the information to be split into two option fields. In this case the client does not accept the information from both options, and you see the error.


Intel has made a fix available to manufacturers to integrate into a future BIOS update. While you are waiting for the next BIOS update, here is a workaround that will allow you to use PXE boot.



As a workaround you can configure your PXE server to shorten the length of the boot menu.


If you have an add-on Ethernet Adapter

If you upgraded the Intel® Boot Agent on a plug-in adapter, then an updated flash update utility (IBAUtil) with the fix is available.

Do not attempt to use IBAUtil on a built-in network connection. IBAUtil can only update PXE on a plug-in adapter. If you have a built-in network connection, you will have to use the workaround until a fix is provided by your computer manufacturer.


Download  IBAUtil for Intel® Network Adapters.

If you updated your wired Ethernet driver In Windows XP* recently, you might have encountered a bug that kept your Intel® PRO/1000 PL Network Connection from connecting to your network.  You might also know this connection as the Intel® 82573L Gigabit Ethernet Controller.

Here is what you can do to fix your Intel® PRO/1000 PL Network Connection that stopped working after upgrading your driver.


1. Download the updated software CD,


2. Uninstall Intel® Network Connections from “Add or Remove Programs” in the Windows control panel


3. Right click on the folder and then click Extract All.


4.  In the Extraction Wizard, use the Browse button to choose the location where you want to extract the CD files. The Desktop is a convenient place for finding the files after extraction.


5. After extraction is finished, you can find the E1EUpdtCD_211237 folder in the location you chose in the previous step.


6. Double-click the E1EUpdtCD_211237 folder.


7. Double-click Autorun.exe. The CD splash screen opens.


8. Click Install drivers and software


9. Follow the installation wizard prompts.


10.  Installation is complete. You may delete the E1EUpdtCD_211237 folder.


This fix will be included as part of the upcoming version 15.2 software release planned for May.


The zip file is huge, about 162 MB. If you want to download a smaller file, you can try an older version of the driver that did not have this issue. You can download version 14.6 of PROXP.exe. The E1EUpdtCD contains later bug fixes that were not in version 14.6, but version 14.6 will probably work OK for most people.


We are confident that the update will fix the loss of connectivity with the Intel® PRO/1000 PL Network Connection. Nevertheless, if the update does not work for you, feel free to post details about what you did and about the issue you see.


NOTE: This E1E Update CD is only recommended for use with the Intel® PRO/1000 PL Network Connection in Windows XP*.
