Q: Hello, does it support iKuai, Feiniao NAS, and Proxmox VE (PVE) systems?  

A:

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:

bash

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

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.

Q: Hello, is it compatible with Windows 7?

A:

It does not support Windows 7. It supports Windows 10 and Windows 11.

Q: Hello, sometimes this network card experiences disconnections and cannot reach 5G speeds.

A:  

1.   For disconnection issues:  

   - Go to Device Manager > Network Card > Open Properties > Advanced, and disable the following power-saving options:

     - Allow the computer to turn off this device to save power  

     - Energy-Efficient Ethernet

     - EEE MAX Support (if available)

   - Adjust other settings in the Advanced options of the network card properties:

     - Disable Recv Segment Coalescing (for both IPv4 and IPv6)

     - Disable Wake from power-off state, Wake on link, and Wake on Ping

2. For speed issues:

   - Check if the Ethernet cable is functioning properly.

   -Ensure that the driver is up to date ([Driver Update Link](http://www.mmui.com.cn/index.php?catid=38)).

   - Verify if the network settings have enabled Jumbo Frames.

   - Check if the switch/gateway device supports 5G speeds.

   - Test if the hard drive uses the NVMe protocol (the hard drive read speed should be higher than the network transfer speed).

   - When testing with iperf3 after enabling Jumbo Frames, use multi-threaded mode.

   - 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.
