            Bug ID: 519832
           Summary: suboptimal connection / connection dropped every few
                    minutes
    Classification: Plasma
           Product: plasmashell
      Version First 6.6.4
       Reported In:
          Platform: CachyOS
                OS: Linux
            Status: REPORTED
          Severity: grave
          Priority: NOR
         Component: Networking in general
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: 1.0

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: CachyOS Kernel 7.0.3 (but same behavior under 7.0.2)
KDE Plasma Version: 6.6.4

Fresh Cachy install with KDE Plasma install with no tinkering with wifi driver
or anything of the sort.

same router & laptop setup, I had no connection issues under Ubuntu 24.04,
Kernel 6.18 (I believe), Gnome

Hardware:
Intel Elitebook, Raptor Lake PCH CNVi WiFi Card

Issue:
download speed fluctuating between peak for very short time to kB/s to 0 until
I restart the network manager or give it some time.

What I've tried:
People on reddit suggested that there might be two supplicants running at the
same time, that of linux/kde and the more modern intel one, which was the case.

systemctl status iwd.serviceerror message wd[3295]: Unexpected connection
related event -- is another supplicant running?

fixed this by disabling legacy backend
sudo systemctl mask wpa_supplicant

and editing 
/etc/NetworkManager/conf.d/iwd.conf
[device]
wifi.backend=iwd[device]
wifi.backend=iwd

that got ride of that error, but it did not solve the issue, unfortunately.

Other things I've tried without success:
-disabling iwl power saving
/etc/modprobe.d/iwlwifi-power.conf
options iwlwifi power_save=0
options iwlmvm power_scheme=1

-reverting to Wi-Fi 5 standard by disabling Wi-Fi 6:
/etc/modprobe.d/iwlwifi-stable.conf:
options iwlwifi disable_11ax=1

-booting the 6.18-26 cachy lts kernel

No change in the undesired behavior, unfortunately.
