Hey, so i recently switched to CachyOS (i’m new to the forum) and i’ve enjoyed it very much, but then this happened: I noticed that my wifi was very slow and unstable, i use a RTL8852BE chipset as i wrote in the topic and i even compared it to linux mint and windows (the problem didn’t show up there), so now idk what to do about it. I can provide you with more info if needed. Here is a screenshot:
oh, and i also use KDE plasma, LTS kernel
Hello,
post output from
grep -H "" /sys/module/rtw89_core/parameters/*
I wanted to clarify that the driver is not in power-safe mode and assumed rtw89_core was in use.
You probably have rtw89_core_git, since you are using the git version.
Can you confirm that it’s not in power-safe mode?
i turned the power saving off on the old driver, but i’ll need to clarify that again. Give me a minute
Check this
run
sudo micro /etc/modprobe.d/rtw89_core_git.conf
paste inside
options disable_ps_mode=Y
strg-s, strg-q
recheck after reboot. maybe it helps
well, that fixed the download/upload speed, but ping is worse (81)
WiFi performance depends on many factors. Although, you’re writing about it being better in mint..
.
you can check lsmod |grep rtw and for each module modinfo <module-name> look for parm
maybe you’ll find something useful.
my modinfo rtw88_core has parm: support_bf:Set Y to enable beamformee support
but it is usb dongle
You know, i tried switching to 2.4ghz since my router is kinda far away from me (i use 5.5ghz now) but my router doesn’t let me change the settings in the web browser. BUT after some nerves and research i wrote this in the terminal: echo “options rtw89_8852be_git disable_ps_mode=y disable_aspm=y” | sudo tee /etc/modprobe.d/rtw89.conf, and it made my ping go from 90 to 23, download from 100 to 340mb/s, upload to 50mb/s. But the wifi bars at the taskbar pmo. While it’s 23ms and 340mb/s there’s 2 bars bruh. Any way of fixing it?
