Hello everyone. I recently purchased this (link: https://www.amazon.com/dp/B0BFPWSMV2?ref...tails&th=1 )10g NIC and am facing issues with achieving the 10G link speed. It’s installed in the second PCIe slot (PCIEX4) on my MOBO board, and the PCIEX16 bifurcation is set to AUTO. The BIOS version is F37a, and the network driver is Marvell AQtion 10Gbit. When I enable full speed, it works perfectly; at 5G or 2.5G it functions fine. Since it’s onboard 1G NICs, I’m unsure if there’s something missing. Any advice would be greatly appreciated!

No, my router isn't designed to handle 10Gbps speeds.

What card do you possess—the SFP fiber module or the 10GBASE-T copper interface? If it’s the latter, do you have any in-wall Cat5 cabling? For the fiber side, which specific SFPs or DACs are you employing? (And if it’s fiber, what fiber grade are you using?)

Would this change how you view your PC screen according to the images? The ATT BGW320 model supports 5G, and it uses a 10GBASE-T Ethernet interface. All cables are Cat6, with fiber connecting the wall to the modem (BGW320).

The router only allows connections up to 5 gigabit speeds.

I've never experienced a NIC that matched my speed or modem performance, which made me think it was only the device status reporting its capabilities. Now I feel a bit awkward. Appreciate the fast information!
