Many Windows users may be familiar with the Realtek PCIe FE Family Controller, especially if you are using Realtek PCIe FE Family Controller driver Windows 10. At times, you may have noticed that the controller is disconnected, or no network is available. At the same time, when you check Device Manager, you may have already seen a yellow sign (!) with this controller icon. Using the Realtek PCIe FE Family Controller Windows 7 can cause similar problems. However, this is not a very difficult thing to solve; but anyway, you need to fix these common Realtek issues to maintain a smooth flow of work. The Realtek PCIe FE Family Controller is a driver located on the motherboard used to run LAN hardware. It controls your computer’s wire network function. It is a controller chipset that edges your computer’s PCI Express (PCIe) bus with GBE (Giga Band Ethernet). Also, it enables you to connect your computer to a strange Ethernet network, and possibly to the Internet from there.
What Is the Speed of Realtek PCIe Family Controller?
If you use Realtek Network Interface Controller 2.5G Gigabit Ethernet, then the maximum speed will be 2.5GB / sec. If you are using Realtek network interface controller is 10/100 / 1000M Gigabit Ethernet, it can provide Internet speeds of up to 1000MB / sec. If you are using Realtek PCIe FE Family Controller is a 10 / 100M network device that means it has a maximum speed of 100 MB / sec. FE stands for Fast Ethernet which is 10/100 MB / sec.
What are common issues for this Controller?
It is common for some users to experience real, Realtek PCIe FE family controller driver or hardware issues. Or, as we have said in some cases above, there is no network available, or it is disconnected from the controller system. Also, when you check Device Manager, it shows you Network Adapter Code Error 12 or Code Error 31. To put it bluntly, there are two major causes of these problems for Realtek drivers: Either the LAN card is out of date, or there is a software problem with the driver running the LAN. In any case, there are many, many solutions available for them. Here today we will talk about the practical and general reforms of these issues.
How to fix the issue?
You can try these fixes to fix the Ethernet bug problem. It usually does not have network hardware and drivers or Realtek PCIe FE Family Controller working on Windows.
Change network controller settings
When the Realtek controller encounters a driver or hardware problem in such a case, the settings can be configured to see if it attempts to restore the Ethernet network. Realtek PCIe FE may help change some settings in the Family Controller Properties. First of all, go to Device Manager and extend the network adapter. Now right-click on Realtek controller driver to open its features. Now in the Properties window, find Properties. Automatically disable Gigabit and reset it to Link, Battery, or AC. Then find Green Ethernet (under Property) and disable it and press the OK button.
Update the Realtek PCIe FE family controller driver
One of the first things you should do is check if the driver is up to date, as it is common with software related to Realtek driver issues because it is outdated. The most efficient and secure way is to update your Realtek PCIe FE controller driver. To do this, follow these steps: First, press the Windows + R key to open the Run dialog box. Once opened, type “devmgmt.msc” and press enter to unlock Device Manager. Now from the device list, click Network Adapter and then locate the Realtek controller. Now right click on the Realtek controller and then click Update Driver Software. When you update the driver, select manual mode, then select the drivers you want to update. Your operating system will look for the necessary drivers for an update. Finally, install the updates and restart your system. After your computer restarts, all the issues related to the Realtek driver will be fixed in advance.
One person noticed that the Realtek PCIe FE family controller problem is known to be related to butt defender internet security because once it closed the firewall the internet started working again. He suggests that you try to deactivate your malware program for a while to see if it solves the Realtek problem for you.
If issues are not resolved using the above method, then, in this case, it may not be a software issue, but it may be a hardware issue. This indicates that the Realtek LAN card in the motherboard is dead. In this case, you have to restore it with a new one. You can buy a Realtek network adapter, and to replace it, you will need a computer hardware expert.
