<p><br/></p><p>Q: Hello, does it support Linux systems? Is it driver-free? </p><p>A: Yes, it supports Linux, but it is not driver-free. You need to install drivers. The driver download link is: Realtek PCIe FE / GBE / 2.5G / 5G Ethernet Family Controller Software.</p><p>Q: Hello, can this network card be used with Synology NAS? </p><p> A: Yes, it supports Synology NAS, but you need to install drivers. The installation of Synology drivers is done through adding packages. The specific installation method is as follows:</p><p>1. Open Synology's Package Center and click Settings .</p><p>2. In the General tab of the Settings window, click the Trust Level section and select the Synology Inc. and trusted publishers radio button.</p><p>3. In the Package Sources tab of the Settings window, click the Add button and enter the following information:</p><p>4. Name: SynoCommunity</p><p>5. Location: https://packages.synocommunity.comor http://packages.synocommunity.com</p><p>Q: Hello, does it support iKuai, Feiniao NAS, and Proxmox VE (PVE) systems? </p><p>A:</p><p>It does not support iKuai. Feiniao requires driver installation. It supports PVE and can also be used with pass-through. To install the Feiniao NAS driver, enter the following command in the terminal:</p><p>bash</p><p>wget https://cjds.com.cn/download/r8126-10.014.01.tar.bz2 && tar -xjvf r8126-10.014.01.tar.bz2 && r8126-10.014.01/autorun.sh</p><p>Note: If your onboard network card is also from Realtek, it will prompt you to uninstall the original network card driver, which may cause the network to disconnect.</p><p>Q: Hello, is it compatible with Windows 7?</p><p>A:</p><p>It does not support Windows 7. It supports Windows 10 and Windows 11.</p><p>Q: Hello, sometimes this network card experiences disconnections and cannot reach 5G speeds.</p><p>A: </p><p>1. For disconnection issues: </p><p> - Go to Device Manager > Network Card > Open Properties > Advanced, and disable the following power-saving options:</p><p> - Allow the computer to turn off this device to save power </p><p> - Energy-Efficient Ethernet</p><p> - EEE MAX Support (if available)</p><p> - Adjust other settings in the Advanced options of the network card properties:</p><p> - Disable Recv Segment Coalescing (for both IPv4 and IPv6)</p><p> - Disable Wake from power-off state, Wake on link, and Wake on Ping</p><p>2. For speed issues:</p><p> - Check if the Ethernet cable is functioning properly.</p><p> -Ensure that the driver is up to date ([Driver Update Link](http://www.mmui.com.cn/index.php?catid=38)).</p><p> - Verify if the network settings have enabled Jumbo Frames.</p><p> - Check if the switch/gateway device supports 5G speeds.</p><p> - Test if the hard drive uses the NVMe protocol (the hard drive read speed should be higher than the network transfer speed).</p><p> - When testing with iperf3 after enabling Jumbo Frames, use multi-threaded mode.</p><p> - In Windows, check if the network card is set to 5G. To set the network card speed: Right-click This PC> Manage > Device Manager > Network Adapters, find the corresponding device, right-click on Properties > Advanced > Speed and Duplex> Value.</p><p><br/></p>
