And it has been. A year in, it's been working away without complaint and I've been plenty happy with it. There's not really much to add - you know what it is and what it's rated at. All I can say is that it's been able to work well and I've had no driver or other issues with it on Linux or Windows. I'll be happy to just use Gtek for any future NICs I need and if they have a 10Gb when I need that, will probably buy from them. With a network card, the main thing you want is for it to work and keep working. This does. Review: Works well with true multi-OS driver support including Windows Server. - Was looking for a 2.5gbe NIC that would work fine with Windows Server 2019 due to the 2 NICs built onto the motherboard not being compatible with Windows Server family (thanks Intel for purposely doing this so users are pushed towards proper server platforms instead of using a consumer one). The Realtek chipset used on this NIC installed without any hassle once got the drivers from Realtek’s global website. granted you will lose available PCIe lanes so may not be for someone that wants to keep 16 lanes for their GPU & multiple NVMe drives on a gaming rig, but general usage overheads are low and no worse than an onboard NIC (a lot of the cheaper NICs rely on software & the CPU to control traffic etc but this seems like a true hardware controlled NIC). Doesn’t seem to slow down under load either which a lot of cheaper cards can do as the controller gets hot, but this shouldn’t be a problem if got sufficient cooling in the case. Very happy with the performance of this NIC and will be buying more of them when required to either upgrade from Gigabit to 2.5gbe connectivity or replace a failed onboard NIC. ## Features - Controller：Realtek RTL8125B - Spec.: Data rate: 2.5Gb, backward compatible with 100Mbps/ 1000Mbps; Single RJ-45 port, PCIe2.1, X1 Lane, work with PCI-E X1/ X4/ X8/ X16 slots; Both Full-Height and Low-Profile Brackets are included - Supported operating systems: Windows 7/8/10, Windows Server 2008/2012/2016/2019, Centos/RHEL 6/7/8, Ubuntu 18/19/20/21, Debian 9/10/11, FreeBSD 10/11/12, Vmware Esxi 5/6.

Yes, this Intel I340-T4/E1G44HT compatible gigabit network card can support link aggregation. Hope our answer helps you. Thanks and best regards. **Q: This will work with ESXi 7 ?** A: Dear customer, Thanks for your question. No, this 10Gtek for Intel E1G42ET gigabit network card doen't work with ESXi 7, because ESXi 7 no longer supports Intel 82576 chip network cards. Hope our answer is helpful to you. Thanks and best regards, Shirley **Q: Does this card support wake-on-lan?** A: Dear customer, Thanks for your question. No, this 10Gtek® for Intel EXPI9301CT gigabit network card (ASIN: B01H6O7X0W ) doesn't support wake-on-lan, but 10Gtek® for Intel I210-T1 gigabit network card (ASIN: B01H6O7TMO) can support wake-on-lan. Here is the link for 10Gtek® for Intel I210-T1: https://www.amazon.co.uk/dp/B01H6O7TMO?ref=myi_title_dp. Hope our answer can help you. Thanks and best regards, Belinda **Q: Do the 2 physical ports appear as 2 separate interfaces in the os - i.e. can i have 2 separate ip addresses and route between them (unix)?** A: Dear customer, Thanks for your question. Yes, you can have 2 seperate ip addresses. What do you mean " route between them “ ？ Usually, this has nothing to do with the hardware network card, you should check this with the system. Hope our answer helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Been solidly doing the job for a year now. *by J***. on 11 April 2026* I always feel NICS are overpriced but this was the cheapest that I could find that actually looked reliable.
