Hi, I have a rtl 8812ae PCI desktop card and I get really poor connectivity in Linux. In particular, I get ping times that increase a lot if I use the connection a lot. What I noticed by comparing with my Intel-based laptop next to it is that iwconfig always reports a rate of 866.7Mb/s, while the rate on my laptop fluctuates in the 100-250Mb/s range. I tried forcing the rate with iwconfig, and it seems to help a little, but it's still not good enough. So I suspect something is wrong with the rate control? I've played around with the various rtlwifi module options and they don't help. I was suggested disable ASPM, but my motherboard doesn't seem to support ASPM at all. On the same computer, the card works as advertised in Windows, so I'm pretty sure it's a driver/software issue. I'm testing with kernel 5.6.19 and linux-firmware 20200619. And the card is a TP-Link Archer T4E. Please let me know how I can help debug this, -- Olivier Crête olivier.crete@xxxxxxxxx
