ASUS XG-C100C 10G Network Adapter PCI-E x4 Card with Single...

"If you're having connection issues using this card, read below for possible fix!I purchased two of these cards to fill a growing 10Gb network in my house. One for my NAS, and one for my media server to save 200 bucks going with Intel T1s. I've had ok luck with Aquantia chipsets on motherboards in the past so I wanted to try my luck here (these cards use Aquantia 107 chips). Upon installing the cards everything seemed ok at first, until I hit speedtest. Upload would error each time, and everything seemed a bit sluggish. Trying new drivers and moving to Cat 7 cables did not work. After reboots a couple days later I noticed both cards showed activity lights but in Windows showed cable disconnected. I spent hours fiddling with settings on my switch, reboots, driver updates and rollbacks, nothing. I set this project to the side for a few months until today. (I should also mention, card in my NAS worked, but still had upload issue to externally WAN side; media server did not work)Messing with it again using drivers off the Aquantia site I raised the transmit buffer from default 4096 to 8184 and now my NAS is speed testing full, and local transfers are much snappier with no sluggishness over RDP. This seems to have done the trick for this card, but the card in my media server still will not work right. In my media server I moved PCI-E slots which triggered a cable connected status and packets flowing, but upon reboot it's showing DC again with the exact above settings. I have not tried a reboot on my NAS to see if the problem is alleviated there 100%, but for the time being this appears to have fixed the issue. I should mention my media server is using an older platform which could be causing other issues.Settings I have set:ARP offEnergy-Efficient Ethernet offFlow control offJumbo Packets offLarge Send Offload (all 3) offMaximum number of RSS Queues - 8 queues (only set to number of threads of your processor or lower as this puts more load on CPU)NS Offload off (only applicable to some Aquantia chipsets)Transmit Buffers 8184Not everybody will have this exact issue, but if you're having this issue or speed problems I would try these settings to see if it fixes your problem.You can find updated drivers off the Aquantia website, the chipset is 107.This product would receive 5 stars if Aquantia/Asus would produce stable drivers applicable to all system situations. It appears some form of this problem exists for a lot of buyers so I rated 3 stars. You can't beat a small compact cheap $100 10Gb NIC if it worked perfect out of the box.Update 6-25-2018:I have since taken both cards out of these machines and went with Intel instead from 10GTek. For my application they were hit and miss whether they would work or not and I refuse to be left wondering if I could leave the house without a NIC going down."
