have the Archer AC 1300 network card and I am constantly experiencing signal loss, latency ranging from 16 to 500 ping, and fluctuations in upload and download speeds from 5Mbps to 250Mbps. It simply doesn't work properly, as if it can't read the signals in the air and does what it wants. Neither the website nor the manual provides any guidance on what to set in the advanced configuration options, which are completely different from any other network card. I never expected the product to be this bad, with no support and no testing before being released to the market.

Meanwhile, I have a 2016 cellphone and a 2014 notebook, both with significantly less powerful specs, sitting on the same desk, running the same programs, and receiving a constant 16-25 ping with 12Mbps download speed without any packet loss.
