I finally got 10gb fiber a couple of weeks ago. Very happy with the install and the speed. However, I would like to get closer to the 10gb. I realize that my router and motherboard chip only goes up to 1gb. So I am currently getting less than I would like to have. I am looking at TP-Link BE800 router and TX-401 NIC. I purchased the NIC first so that I could be sure the NIC would work in my older computer (Asus Z170). The MB doesn't have a PCIe x4 slot which is required for the NIC. It does have an open PCIe x16 slot of which I installed the NIC. It installed without issues. But, when I run any speed test it disconnects from the internet and I have to boot the computer. Sometimes the speed test will complete and sometimes stop before finishing If I don't run a speed test the NIC seems to work fine on the internet. I spent couple of hours with TP-Link chat and no change in the issue. Any ideas would be appreciated.
