Review on High-Speed Network Connectivity: Jeirdus Ethernet Gigabit Desktop PCIe Network Card Controller Adapter with Intel 82573L Chipset 10/100/1000M by Jyothish Pillai

This card is rated for 1000 but its top speed is about 860m. It's fine for my use case. I have 400 Mbps to 480 Mbps from my cable provider. It handles my bust speeds just fine, but when I use the second port as my LAN, the download speed drops to 360Mbps. It can't transmit 400m (WAN) and 400m (LAN) at the same time. I worked on this using my PC's built-in LAN port, which is also 1000, so I'm no longer bottlenecked. fits most use cases, but the standard bracket is about 1/2 inch too big and doesn't fit properly in the PCI slot. All in all, this is a great buy for the money. I can't use the second port for my LAN, but it might be nice to use it later as an OPT interface.
