**
Ubuntu Version**:
Example: 25.10
Desktop Environment
Example: GNOME
Problem Description:
From time to time, I am getting popup with error message “Connection error. Activation of network failed”. At this moment I can dop nothing as it is a hard freeze, not even REISUB works.
I can get this error within minutes after booting, or hours, or not get it at all. Looks too random to me. This started probably about 2 weeks ago, Ubuntu freshly installed - Dec 21, 2025.
Relevant System Information:
I have tried to upload result of wireless-info but it failed
Pastebin failed, error message is: Failed to contact the server: HTTP Error 400: Bad Request.
I also found similar topic, but unfortunately author did not provide any info, and it was closed. So I decide to create a new one.
My hardware:
HP Z2 Mini Workstation G1a:
AMD Ryzen AI Max 395, 128GB RAM, 4TB SSD (WD Black 850x).
Network : Realtek RTL 8125, kernel driver and module - r8169 (2.5G)
Wifi - Mediatek , kernel driver and module - mt7925e
________________
I can provide any other info if required, I would really appreciate any help. I do not want to install from scratch.
Also, I do not want to switch to LTS version, it is too old. Had quite a few problems with it, tested for 1 day and couldn’t use it so reverted back to 25.10.
