Unstablet workin wifi on raspberry pi3 whit OS LEAP 15

Hello.
I do not know if I chose a good forum department, but I have a problem. I installed a leap15 image on raspberry pi3 from the images available at opensuse.org. Everything starts nicely. However, when setting the wifi connection using YaST2, then by testing the ping for the local machine, some of my packages are lost. On average, 50% are lost. Also as it normally works this connection fades. I’ve tried a few tips (https://lists.opensuse.org/opensuse-arm/2016-11/msg00019.html). However, this problem still occurs. In addition, I attach a log file from a fresh installation.

Although I’m sure you’ve installed LEAP 15, you should still describe where you downloaded your image from (web page,location, etc)

Did you run a “zypper up” after installation?
You should always do that to pull in any late fixes and improvements.

I noticed you’re running at least postfix, maybe a full mail server.
You might want to stop the service while y’re troubleshooting.

How do you know whether you’re dropping packets?

Hello.
I am sorry that I did not answer for so long but I had a lot of things on my mind and I did not have time.

I open the openSUSE installation from here: http://download.opensuse.org/ports/aarch64/distribution/leap/15.0/appliances/openSUSE-Leap15.0-ARM-XFCE-raspberrypi3.aarch64-2018.07.02-Buildlp150.1.1.raw.xz

That’s how I use postfix. It was turned off and it was still dropping packages. However, I noticed turned on Network Manager. I thought about turning it off and whether it would give something. The service has been stopped. And the problem was solved in this momeent.

I’m not an expert in this, but I’ve muddled through an issue that seems similar. You haven’t provided enough information for me to be sure. But I had the same problem with both DNS service dying after the system started up, and then having the system drop 50% of the network packets as I was trying to do a software update. (A reboot and restart of the update then worked perfectly.)

The key question is whether you have a RPi-3B or RPi-3B+. If it’s a 3B, the install and update should work with no problems. If it’s a 3B+, the XFCE and X11 distributions of Leap 15 aarch64 have flawed network drivers in the distribution that make it difficult to do the needed patches and updates (those were the problems I was seeing). Ethernet doesn’t work at all, and WiFi is unreliable. If you’re using JeOS, Ethernet works fine and (in the distro) WiFi isn’t activated. (But the thread below has some suggestions on how to start with JeOS and then layer on XFCE or X11: that might work best for you if you’re prepared to do a fresh reinstall.)

If you can make a network connection work at all, I suggest you execute the following command in a terminal window:

zypper -vvv -t patch --no-recommends

that will make sure your system is updated to correct problems in the original distribution. That alone may fix your problem.

But also take a look at this thread, which I think may be relevant. At least it will give you some more background information that might help you debug your situation:
