SUMMARY
***
Hi, I recently use kernel linux-next for testing (2023-02-25)
And I noticed a lot of warnings like these in dmesg
***

[   17.498170] fuse: init (API version 7.38)
[   19.394370] Bluetooth: RFCOMM TTY layer initialized
[   19.394383] Bluetooth: RFCOMM socket layer initialized
[   19.394392] Bluetooth: RFCOMM ver 1.11
[   19.407496] warning: `kded5' uses wireless extensions that are deprecated for modern drivers; use nl80211
[   19.440415] warning: `Qt bearer threa' uses wireless extensions that are deprecated for modern drivers; use nl80211
[   19.440680] warning: `Qt bearer threa' uses wireless extensions that are deprecated for modern drivers; use nl80211
[   20.494578] warning: `plasmashell' uses wireless extensions that are deprecated for modern drivers; use nl80211

However, it does not seem to cause any trouble
So, I just point out (in case it's not already known and if it needs special attention)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Slackware (current)
KDE Plasma Version: 5.27.1
KDE Frameworks Version: 5.103
Qt Version: 5.15.8

Looks like the kernel needs to set some build flags. https://fedoraproject.org/wiki/Changes/RemoveWirelessExtensions
Comment 2 Siddhartha 2023-07-09 15:22:55 UTC 
I'm getting a similar warning on Linux v6.4.2 and kded 5.107:

`kded5' uses wireless extensions which will stop working for Wi-Fi 7 hardware; use nl80211
Comment 3 Tim Murphy 2023-07-17 20:46:32 UTC 
Not to pile on; but I am also seeing message 'warning: `kded5' uses wireless extensions which will stop working for Wi-Fi 7 hardware; use nl80211'. Manjaro latest, kernel 6.4.3-1-MANJARO

Hi, I became aware of the error shown by dmesg on the machine here yesterday and while discussing it on IRC was referred here by a more advanced user.

Comment 6 David Faure 2024-03-09 08:20:43 UTC 
The issue is in Qt and/or the Linux Kernel, nothing we can do at the KDE level. See:

The upstream Qt bug seems to be https://bugreports.qt.io/browse/QTBUG-114336
