Hi!
I’ve tried searchigf the forums and the general web, but to no avail. I got myslef a USB Wi-Fi adapter, TP-Link AX1800, and installed this AUR package AUR (en) - rtl8852au-dkms-git
The adapter works, but is much slower than expected. Its download speed on my 1Gb optical fibre net is about 100-120 Mb/s (the upload speed is much higher, 300-400 Mb/s), whereas on my mobile at the same spot the download speed is easily 300+ Mb/s and another PC in the room with a different card has about 500 Mb/s.
I tried kernels 6.6.65 and 6.12.4, but it doesn’t seem to make a difference.
My inxi -Fazy output (network section) is below. I’m surprised the adapter’s speed is listed as 480, because it’s connected via a USB 3.0 and supposedly supports that, but I don’t think this has anything to do with my problem, because I’m not nearing that speed anyway.
Yes, sorry if I wasn’t clear, but I connected the wi-fi adapter via a USB 3.0 cable to a USB 3.2 slot. I don’t understand why inxi thinks it’s 2.0. I tried another USB 3.2 slot and it was the same.
Indeed, it looks like it’s reported as 2.0, too. Confusing.

But when I connected an external USB disk to the same slot, it does report it as 3.0, so it must be something with the adapter or the cable that was packaged with it, I think? Or could it be that the drivers are the cause somehow?
