Intel x540 2t 10 gig Nic win 11 disconnecting

Hi all. Ross here.
I thought I would try my luck here, As I am in a pickle. I recently install the Intel x 540 from 10gigtek into my new matx system. since I am using windows 11 the drivers are windows 10 based. Intel has since dropped support for these Nic’s so drivers are what they are. It is working fine for the most part. However I am experiencing random disconnects. mainly when gaming however also in the desktop. space. I am guessing I may need to replace the NIC with an item that has windows 11 support. does anyone here have any recommendations for what I should do next?

would the problem be any less off if I switched the NIC to SFP?

thanks fort he help in advance.

x550-t2 is a better one.

I have couple of x540-t2. They are fine in general. However, they are picky about the network switch you paired with.

I had a tough time getting x540-t2 working at full speed on my AM4 boards. Tried two cards, both from eBay, one dell and another supermicro. Spent a lot of time on all sorts of intermittent performance issues and never got consistent speeds. Lot of retr in iperf3.

Much better results after switching to gTek x520 SPF+ cards, connectX3 also seem to work well and Trendnet AQC107 based RJ45 also are working. I now have four devices with athese cards and network consistently gets me 9.9 Gb/s

I literally spent hours messing with my configurations. Good learning opportunity, but frustrating nonetheless.

Forgot to mention Mellanox ConnectX3 and AQC107 are running in linux, x520-d1 in windows. In your case I would try x520, they are cheap and can be returned if they do not work and are bought from Amazon or similar.
I would pay attention to the PCIe slot where the NIC is going in, these modern boards have very limited lanes in those bottom slots.

Try disabling power saving on the partner device. Some cards downgrade the Ethernet connection when idle to save power and the x540 only supports 10G, 1G, and 100Mbit modes. Attempts to connect at multi-gig or 10Mbit will fail.

Just checked your board and PCIe4 x4 slot should be fine for NICs I mentioned.
