Re: [SOLVED] Very slow wifi speeds after coming to Arch

does that and the next boot reflect the altered kernel commandline?

yup

Module = "rtw88_pci"

    coresize            = "40960"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "1"
    srcversion          = "F235F522B575430E717BD70"
    taint               = ""
    uevent              = <store method only>

Re: [SOLVED] Very slow wifi speeds after coming to Arch

I decided to just try installing https://aur.archlinux.org/packages/rtl8821ce-dkms-git and it seemed to have made my internet better (to a point where I'm happy with it), but it's not even using the kernel so I assume one or more of the dependencies did something; assuming they auto install along side the package when using "pacman -S ". I'll mess around with this more later, but I'm going to mark this thread as solved.

Note: for future reference (mostly for myself cuz brain dumb ), as I was still using the old kernel, removing "rtw88_pci.disable_aspm=Y rtw88_core.disable_lps_deep=Y" from etc/default/grub made it worse.

Edit: I'm not used to packages so for other noobs like me, the rtl88-blablabla install sh is in the folder titled pkg and through all the single folders. So run that with bash or sh cuz I saw both and blacklist whatever kernel isn't working so it uses the new one and reboot (also the readme in the same folder has links to some dependencies and instructions for ubuntu and debian). And you can prob remove "rtw88_pci.disable_aspm=Y rtw88_core.disable_lps_deep=Y" from etc/default/grub if it worked.
