Don\'t bother with this if you use modern versions of Windows

Intel does not offer drivers for newer versions of Windows (Win7 and Win10 as of this writing). You will end up using an old Microsoft driver with limited features. This makes it no more useful than the most basic NIC that you can buy for a fraction of the price.I\'ve also noticed a problem with the performance. I don\'t expect a full 1000 mbit/s with the PCI interface but it should be close. I was only getting speeds of about 500 mbit/s. I wasn\'t able to test if it was due to the driver since well, there is no other driver to test. Instead I grabbed a Realtek based PCI NIC that I had also purchased (https://www.amazon.com/gp/product/B004F3CO5M). Realtek still publishes drivers for that chipset. The ones I installed were just 3 days old. Realtek performed at about 750mbit/s which is much closer to what I expect with the PCI interface.I really only bought this Intel NIC because Intel has a good reputation for quality and features, something I was willing to pay a little extra for. That\'s a complete waste if you use modern versions of Windows. Just don\'t bother with this Intel NIC. Get something cheap that uses a good Realtek chip. You\'ll get proper driver support and you can use features like VLAN\'s.


Great for a FreeNAS build with a legacy logic board

My Haswell era logic board, which is used for a FreeNAS build, has a flaky on-board Realtek LAN chip. The board\'s two PCI-e slots are filled with SATA controller cards, leaving only two regular PCI slots free. I bought this Intel PCI network adapter to fix the networking problems I\'ve been having. FreeNAS dashboard reports 95MiB/sec, which is great, and the same as the performance of the Intel PCI-e cards on another system I have. I\'ve transferred about a terabyte of data over it so far without any problems.


Dated but still quite usable NIC

Bought this card 10yrs ago, but never used it as I later bought the “CT” version and installed using a spare PCI-e expansion connector in my old Win 7 eMachine desktop. Well, I now need two PCI-e slots for video and eSATA cards, and having a spare PCI slot available, I dropped in the PRO/1000 GT card...after booting up, Windows immediately recognized the device, automatically provided the driver and 30sec later was on-line. Did an Ookla SpeedTest, and got nearly 500Mbts/sec download, identical to the CT version, so all is well. As other customers have noted, this device has only “in-box” support now, so the only drivers available are assigned by Windows -and they are over 10 yrs old - as this is a legacy NIC. Yes, very much an old-school Ethernet adapter, but it delivers the goods, so who’s complaining.


A little more expensive but decently fast

Getting promised speeds and has lasted since I purchased it.


1K speeds. Plug-and-play

1K speeds. Plug-and-play. Windows will find drivers.
