I've also tried different and known 10 Gbps capable cables.Īs soon as I enable the Intel NIC and disable the on board, all is well again. I have tried a different SFP module, I have even tried it into another 1 Gbps switch using copper and I don't get much over 90 MB/s writing to the NAS.
The NIC has driver version 10.45.928.2020 downloaded from Realtek which I believe is the latest. If I use the Realtek NIC, I can write to the NAS at around 280 MB/s but reading from it struggles to get above 90 MB/s - not even near 1 Gbps. Using the Intel NIC, I can copy a file from my NAS to my PC at line speed (1GB/s), write is somewhat slower due to it being a RAID 5 array on the NAS, but still it's over 400 MB/s. I also have an Intel X520 10 GbE PCI card plugged in along with 10 Gbps network between my PC, NAS and some other devices.

If nothing is working, then replace the Ethernet cable and get the high-speed supportable cable from the market. Once the installation finishes, restart your PC and check if the problem is solved or not.
After the download finishes, open the installation file and follow the onscreen instructions to install the latest drivers.
Google for “Realtek PCIe GBE family controller latest drivers download” and then download the driver installation package from the site.
Let’s learn how to update the latest “Realtek PCIe GBE Family Controller” software or drivers. If your router and Wi-Fi adapter both support 1 GBPS speed, then the problem could be the software. If there is no 1.0 GBPS option available in the Value section, that means that your router or network adapter aren’t supported with 1 GBPS speed.
Under the “Value” section, choose the “1.0 GBPS Full Duplex.” Under the “Property” section, you will find a list of properties, and there you have to tap on the “Speed and Duplex.” (the adapter will have green signals)Īfter that, select the “Configuration” option and then go to the Advanced tab. Right-click on it and then click on Properties. There you will find the network adapter that is currently in use. It will bring the run dialog box on your screenĮnter “ncpa.cpl” on the Run dialog box and then hit the Enter key. Hit “Windows” + “R” keys together on your keyboard. Let’s fix the issue by tweaking some configurations that might affect the performance of your network controller. So let’s start and fix the issue.įix 1: Configuring the Settings on Your PC Now you know what factors are responsible for preventing the speed of your network. Upgrading to a high-end adapter can enhance the speed. Incompatible Adapter: If your Wi-Fi adapter carries less speed than your router, it will affect the speed of your PC. If your cable is not compatible with the speed of your network, it will prevent your internet from running on high speeds. Unsupported Ethernet Cable: In order to get the full potential of your network speed, your Ethernet cable must be supported with the speed that your network provides. By tweaking some settings of your network controller you can get rid of the slow speed. Maybe a setting is restricting the speed of your network adapter. Incorrect Configuration: If your network adapter settings aren’t configured properly, then your controller can be limited in providing internet speed. Below we have provided some basic factors which can affect the speed of your network adapter: Let’s see what is preventing your Realtek PCIe GBE Family Controller from running quickly. If you are also facing the same issue on your PC, then we are here to help you. What is causing the Realtek PCIe GBE Family Controller to run on Full Potential? So, what is preventing the PC from running at full speed of your connection? Let’s see how to solve this problem. At the same time, other devices can run at full speed. Many users are claiming that they are not getting the speed on their PC, which their network offers. However, some people are not satisfied with the speed it provides. One of the best selling components of Realtek is its network adapter chips which are used in most of the computers these days. Realtek possesses a large business of microchips, and large computer manufacturers mostly use its microchips in their products.
Realtek is known for manufacturing semiconductors and distributing them worldwide.
