I am on Leap 16.0 and and the PC is 0,5 meters from the wifi router. For some strange reason wifi (managed by Network Manager) disconnects and connects randomly.
Other devices in the network do not have the same problem - it is located only to my desktop PC.
It has dualboot with Windows 11 (for some certain software) and Windows does not experience the problem, so I do not think it is related to the wifi hardware.
How do I dig deeper into this issue?
Can I find logs that gives a hint on what there is going on, since it is quite annoying, because I have a NAS attached to the network, and thus have to remount the shared drives every time the network reconnects.
Thank You for looking into this issue!
The systemd Journal should be logging why the WLAN connection is dropping.
You may have a problem with your WLAN device driver – please post the output of:
> lspci | grep 'controller'
And then for the WiFi controller dealing with your WLAN –
> lspci -v -k -s xx:yy.zz
where xxx, yy and zz are the numbers at the left-hand side of the previous “lspci” output related to your WiFi controller.
lspci | grep 'controller':

Running īnxi -Nnaz is better for providing such information.
You could watch the journal while the Wi-Fi ocnnection is active:
sudo journalctl -u NetworkManager -f
I ran a continuous logging of the network Manager activities as deano_ferrari suggested. To me it looks like the problem is related to the router? Or am I wrong?

The systemd Journal is indicating that, you connected to the WLAN at 5 minutes before midnight and then, beginning at 30 seconds after 04:25 hours (early morning) the Network Manager state dropped from “CONNECTED_GLOBAL” to “CONNECTED_SITE” –
- Meaning that, your Router dropped the connection to your ISP –
Or, your ISP forced your Router to disconnect – for reasons I’ll explain in a minute.
At 24 seconds after 04:26 hours the Network Manager reconnected to the WLAN and, 51 seconds after 04:26 hours the Network Manager state changed back to “CONNECTED_GLOBAL”
Some ISPs drop the broadband connection to their customers’ Routers at some point in time in the small hours of the morning –
- To force the Router to take a new IP address – usually a new IPv6 address.
They do this to force any ongoing data transactions to cease and, recover if and only if the data transfer is robust enough – in other words, as a “normal” household, there shouldn’t be any ongoing data transfers happening at that time-of-day – except for system updates and, they’ll normally recover if the Internet connection temporarily drops during the update execution.
If you look closely at the Broadband connection between your Router and your ISP, you may notice that, the IPv4 is carried via a DS-Lite-Tunnel or, something similar.
This means that, your Router no longer has an IPv4 address – only an IPv6 address.
Your IPv4 traffic uses an “IPv4 shared address space” – the details are here: <IPv4 shared address space>
It’s yet another method to deal with the rapidly depleting pool of available unique IPV4 addresses.
And, I suspect that, that’s also a reason for why your ISP is forcing your Router to drop all active connections in the small hours of the morning.

Thank You for looking into this. Seems like it is not an OpenSuse issue, but merely located to my wifi-network.
The wifi was disconnected and connected again at 19.15 tonight. So the late night scenario is probably not the explanation. Also I there could be running - and in my case there will be - late night remote cloud backup-jobs over the network.
Could the unstable connection eventually occur because the main router skips connection to the router next to my desktop computer in a mesh system.
If I can find ASUS logs there might be hints.
I will post the results here.
On this Desktop machine connected to my DSL Router via an Ethernet cable, I also see the Network Manager state changes when the machine enters the Suspend state and then is resumed.
Turned out the the issue was caused by a faulty router.
I noticed some errors in the router log, contacted ASUS support and they said that the router was old and added that I could only expect some 5-7 years lifetime for a router…
Interesting (and worrying) information from a router manufacturer.
I then connected another router and since then there has be no disconnects.
So the lesson learned in this case is to check router logs for errors before thinking that something is wrong with the local software.
Thank You to @deano_ferrari and @dcurtisfra for looking into the subject 
Thanks for the update. Not surprised by this finding. Occasionally a router may require a restart as well.
