So unfortunate... I bought them because of the reviews on reliability and stability...but I am running Win 10. If these don't work out I'll return them and look for something that can work with Win 10. Not ideal but this will be the last thing I'll try before going back to a couple TiVOs that can do the heaving recording lifting and I can use KMTTG to pull the recordings off.The ct series nics are older and may be a little hit or miss. I don't use them because there are no drivers for windows 10 for it. I have had good luck with i350 and x540 nics. I think a i210 should be good also. Just don't use an old pci nic. Please note, I have a lot of data going through my nics as I use my server for many things including quite a few security cameras. In any event let me know how it goes.
I think the part that is the most frustrating is that, overall, my network is very performance-based. I use a few enterprise HW components and all my house is wired for CAT-6. My HUBs (and major networking components) are pro-consumer (Ubiquiti) and my inter-household traffic is extremely fast. Swapping the NICs would be (one of) the last networking components I can think to upgrade. Why this is having as many hiccups as it does, puzzles me a bit as I would think more folks would hit this same issue. That said, my household has a very significant number of concurrent connections which make me wonder if my router is underperforming.
