Realtek PCIe GBE Family Controller performance issues

UPDATE-2014 driver now available! (Driver number will be different than what is in this article!

If you have the Realteck PCIe GBE Family Controller adapter and are experiencing performance issues on your network, download the latest driver.  The driver (Version 7.65) is far superior to other Realteck PCIe GBE Family Controller drivers.   The driver is shown as 7.065 on the website.

Our performance issue involved ApplicationXtender an archive system that uses Microsoft SQL to scan documents.   This type of application is dependent on a reliable network and speed.

You will notice that the 7.065 driver is really the 7.65 driver once it is installed (at the time of this writing).

    Can I ask..what is the reason for disabling everything but Flow Control? Just curious. I’ve had issues with my Realtek controller since 2011, when my current PC was brand new. It disconnected all the time and/or the cable wouldn’t be recognized so i couldn’t connect. I finally gave up using the Ethernet connection and switched to Wireless (I have a wireless adapter in my PC as well). I wanted to get a stronger Internet connection, so I decided to switch back to the Ethernet cable yesterday–but I’m already experiencing the same issues I did from the start. I thought maybe a driver update was in order (even though that didn’t help in the past), but I don’t want to bother with it if it’s not going to work. I found your post with a Google search and after reading it I thought maybe the driver update couldn’t hurt–but I wondered about that Flow Control thing.
    Thanks in advance for any info.

    • Ethernet flow control, or 802.3x, is a way for a network device to tell other devices that it is overloaded with data. With the mix of devices we have today from smartphones, smartTVs, netbooks, tablets, gaming stations and other devices, Flow Control can help your network. It in its basic form it allows a device that is receiving data faster than it can process to pause.

      In other words, an overloaded device will send out a pause frame, that asks the device on the other end to stop sending data temporarily.

      Did you notice any improvement?

    The Realtek GBE Family driver version is now version 7.86.508.2014,in which I have now have installed the latest version on my Win 7,with no conflicts that I can tell,so does the same apply to this version too,to disable all but flow control,because when going through the advanced settings options,not all can be disabled,so do I just disable all the options I can disable still ?
    Thanks in Advance !!!

    I would like to keep the WOL setting Enabled. What problems would cause?

    Hi I did all the instructions, installed new driver, disabled everything but flow \control, but the speed is stuck at 100Mbps (it wouldn’t go to Gigabit full duplex speed). Any idea why? I am using ethernet cat5e cable.
