Extremely inconsistent network speed over WiFi

I have just installed artix on my new lappy from the latest ISO and have noticed that my WiFi speeds were abysmal (I'm talking 1~3mbit on a gigabit fiber network, WHAT). After a bunch of messing around with drivers and kernel modules I managed to get to a state where I get anywhere from 1 to 10% of the expected network speed (so anywhere from 25 to MAYBE 120mbit) and it's really inconsistent. I have tried using a Ubuntu live USB using the exact same driver (rtw89_8852ae) and I get a much more reasonable ~600mbit down and ~110mbit up. My brother runs plain KDE Arch, we both have Realtek NICs (slightly different models), but he can get up to speed no problem. This makes me think Artix is doing some weird sysctl trickery or something, because I really have no idea what else could be causing this.


A bunch of commands I ran:


Code: [Select]
➜  ~ sudo lspci | grep -ie "network"
01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8852AE 802.11ax PCIe Wireless Network Adapter

Code: [Select]
➜  ~ sudo find /sys | grep "drivers.*01:00"
/sys/bus/pci/drivers/rtw89_8852ae/0000:01:00.0   # This is the driver
[...]


Any idea on what to do next to diagnose the problem?


P.S.: This is artix KDE using NetworkManager

you might be right in point of failure, this post suggest such

so just wonder how it was different to the previous OS

it was better, or just slightly, or much better, etc..

I agree that the poster on the other thread should have posted what solved their issue.

But if you do have the same issue one way you might discover what sysctl setting to change is to output all the settings to a text file on both your Ubuntu live USB and artix install eg
Code: [Select]
sysctl -a >ubuntu.txt
and then diff the files.
See if there's any differences that seem relevant and then on the fly changing the values to see if it helps.

Also I would try temporarily disabling NetworkManager and connecting the wifi on the command line.
If the problem persists it's a low level kernel / driver issue. If not it a higher level NetworkManager etc issue.

Usrally WiFi speeds won't come out to be any where close to a hard wired Ethernet cable as your relying on a radio signal  that can degrade depending on several environmental  factors which include  your proximity to your router or the nearest access point.  So in conclusion WiFi speeds will  very rarely even come close to that of a hardwired connection and even a hard wired connection won't always be exactly the precise speed that your ISP promises do to the fact that once the network traffic is modulated down from the speed of light to to electrical impulses you won't only lose a certain amount of speed in the  down  modulation do to amoung other factors  energy loss do to heat.

That hasn't been my experience, wifi and ethernet are about the same for me with only a very small speed loss sometimes, when everything is working correctly with wireless N. I turn off 5GHz and use 2.4GHz only on my router as it doesn't work well with my older hw, it results in an inconsistent unreliable and often slow connection. (Alternatively you can find the 2.4GHz BSSID and use that in place of the SSID to specify the 2.4GHz connection only.) Others have the opposite result and claim 5GHz is faster. The ISP promised line speed is not the speed seen on Ookla speedtest etc. nor is the Ookla speed the actual sustained download speed you see while updating though.
