Review: does not work in my application - does not work in my application - Dell 7070 and VMware
Review: This network card is exactly what I needed for faster wired connectivity. Installation was simple, and the card was recognized immediately without any driver issues. The Realtek RTL8125 chip delivers consistent and reliable speeds, making it perfect for gaming, streaming, or large file transfers. The build quality feels solid, and the card sits securely in the PCIe slot. I’ve noticed a significant improvement over my previous 1Gb network card, with stable and smooth performance. Overall, this is a high-quality, easy-to-use upgrade for anyone looking to boost their network speed. Definitely a five-star choice for home or office setups.
