Hello,
I have sometime ERR_NETWORK_CHANGED, I tried to disable ipv6, seems to work but I need ipv6 for an app I use, so it’s not a solution for me.
If it’s possible to only disable ipv6 for my web browser (sidekick a chromium browser), but I didn’t found a way to do it…
any idea?
No idea. Don´t know what you talk about.
When I use my web browser, sometime I get this:
Only happens on manjaro, no issue on windows
For instance
you might have several valid wifi connections, several AP’s that can provide your internet connection.
They all might be close and of similar strength - and you might be switched from on to the other from time to time, when the signal level changes.
It’s just one possibility …
We don’t know how you connect to the internet. 
manjory Manjaro 
Maybe you have an unstable connection. Too far away from your router, broken cable, broken VPN, outdated or wrong driver.
Please give more information about your system
I’m using ethernet cable, I’ll try to use another one, and no VPN.

This will happen everytime your network changes for whatever reason and Chrome tries to use a cached connection, which of course, is no longer valid as you have changed your network.
Running:
$ sudo journalctl | grep 'state changed'
can show you when it happens.
Anyway, this is harmless and Chrome will normally create a new connection that it will cache again, just a little annoying.
This is the result:

Something is amiss. Possibly a faulty network cable?

Only twice per boot. I’m presuming at start and shutdown.
Onboard NIC Realtek RTL8111/8168/8411 is using r8169 driver
I suggest you install r8168 driver that will probably work better with this hardware
sudo mhwd -i pci network-r8168
( Or Manjaro Settings Manager > Hardware Configuration if you prefer GUI tool)
Manjaro hardware detection should install r8168 driver and blacklist r8169 driver
It might also be beneficial for onboard devices to update motherboard BIOS
X470 GAMING PLUS MAX | Motherboard | MSI Global
I installed r8168 driver, but still same issue.
I just updated my BIOS, I’ll see if it’s fixed.
This message pops up when the browser detects a change in network.
So presumably your system is changing the way you connect.
This triggers the browser to warn you that something is wrong.
There are some virtual network interfaces that might be confusing NetworkManager?
Looking into the messages NetworkManager generates in the log should give some insight into what is happening.
… doing stuff like grepping for such specific terms may not be too helpful
it would likely be more useful to just watch what is going on - in it’s entirety - not filtering for specific terms like that
for instance
have one of these commands running in a terminal at the time the glitch occurs …:
journalctl -f
or:
sudo dmesg -w
and see whether something emerges - why your lease is lost and a new one needed …
Looking in connections and this is what I have:
I don’t know what is “Io” 
Could docker cause the problem?
(I got the error while editing this message)
loopback interface
it’s always there - but not supposed to show up in NetworkManager
… from what I gathered: it was a bug in KDE that has been fixed by now
update your system?
apart from that, your screenshot is not helpful - it contains the same information that is already contained in the output of inxi that you posted (5-th post here)
read through the logs - or watch it happen live
I posted two commands to do that - you have not responded to that.
I disabled docker and it seems to fix the issue. But why docker can cause this?
Here the result of the commands:

You probably misconfigured your containers.
If disabling docker seems to solve the issue there could be a connection, check your network settings and start learning : Network configuration - ArchWiki & Docker - ArchWiki
please use formating when posting logs.
Reading the dmesg log
[71697.076658] device veth935e846 entered promiscuous mode
This mode is useful to capture traffic not intended for the interface in the same network. Are you sure you need a card reading all traffic on a interface in your docker?
I guess they copied instructions without understanding.
Probably the docker container took over the internet connectivity.
