Description jcdepner 2026-02-06 14:06:55 UTC
Whenever I open an instance of Dolphin, my network connection disconnects and reconnects.  I have both hard-wired Ethernet and WiFi on this system and it happens regardless of which I'm using.  This does not happen with Nautilus, Thunar, et. al.  This is repeatable on my system.

dmesg output for WiFi:

Do you have any network folders (smb, ftp, etc.) configured in dolphin?
Comment 2 jcdepner 2026-02-09 17:51:57 UTC
Hi Tobias,

I have some folders that are being exported/shared via NFS and SMB from 
this system but they're not configured in Dolphin.  By "configured" I'm 
assuming you mean NFS and/or SMB folders that are mounted and show up in 
Dolphin.

I've been using Thunar for the last few days (I don't like it near as 
much as Dolphin) and I've done a couple of updates/upgrades and now, 
trying Dolphin again, I can't get it to repeat.  I've switched the 
default file manager back to Dolphin and I can't get it to disconnect.  
I spent 45 years as a professional programmer (FORTRAN/DISSPLA, 
C/Motif/Qt, C++/OpenGL/Qt) so I know that there is nothing more annoying 
than a non-repeatable bug.  Or, as Microsoft used to say, "if it's not 
repeatable, it's not a bug".  So, until I can get it to start doing it 
again (and I hope it doesn't) you might as well let it slide.

Thank you so much for getting back to me so promptly and thanks for a 
really great file manager.

Cheers,
Jan

Hi Tobias,

     It started up again.  I have no idea what's going on.  Is there any 
kind of debugging I can do to get a clue?

Cheers,
Jan

Hi Tobias,

     One more thing, I'm running another Linux box (Kubuntu 24.04 like 
this one) and it doesn't have this problem.  It does mount the NFS 
shares from this system though and they show up in the sidebar of 
Dolphin.  On this system the SMB shared folders show up under 
"Remote->Network->Shared Folders (SMB).  I stopped the SMB servers and 
that didn't make any difference.  If there is anything I can do to try 
to clear this up please let me know.  I doubt that this is a major 
problem since it seems I'm the only one experiencing it ;-)

Cheers,
Jan

Hi, I'm afraid Dolphin 23.08.5 and Plasma 5.27.12 no longer receive updates or maintenance from KDE. Dolphin is a fast-moving project, and bugs in one version are often fixed in the next one. It's possible that the bug only exists in 23.08.5, and I see the problem doesn't happen on another system with Kubuntu 24.04.

Your options at this point are to either update Dolphin, or to contact Kubuntu for support for your existing install. Thanks for your understanding.
