Since I updated from 19.01 to 19.08 my wifi connecting is not working proberly. After every second or third booting it doesn’t connect to the router. The networkmanager is telling “connecting” but it can’t establish.
On board is a Intel Corporation Centrino Advanced-N 6205 card.
“modprobe -r iwlwifi ; modprobe iwlwifi” says that iwlwifi is running.
Does not connect at all or drops out of connection?
Make sure to have the package firmware-iwlwifi installed. You can also try grabbing a newer package version from unstable or experimental of that package as it only contains binary blobs.
Then maybe the driver itself has an issue which is fixed with a newer kernel.
You can try installing the newer linux kernel 5.3 from buster-backports.
Activate buster-backports in synaptic or by adding deb http://deb.debian.org/debian buster-backports main
Then install the packages linux-image-5.3.0-0.bpo.2-amd64 linux-headers-5.3.0-0.bpo.2-all-amd64
After installation reboot the system to use the new kernel.
thx for the reply. As proposed, I installed the newer kernel but I’m not quiet sure if it has been successful. Systemsetting is telling me netrunner 19.08 Indigo and kernelversion 4.19.0-6-amd64 (?).

But there is no improvement with the wlan connection. Almost every second booting it does not connect to wlan at all. Sometimes even the wlan is not shown in the list of possible connections. To click in the kde network manager for connecting fails also. And in the most cases the rebooting helps but this is very annoying procedure.
I have always the feeling, and it’ s only a feeling, that the system doesn’t catch always by booting that there is wifi-card. This may be the reason why there is sometimes no wifi-connection at all in the kde network manager. And there have to be at least more than 10 wifi-routers in the neighbourhood …
I checked the wifi on/off switch and it looks pretty well.
I also checked it with the win7-os on this machine four times and I didn’t had any problems. Always the connection has been established.
The i tried it with a netrunner 19-08 live dvd and … no connection possible. Then I checked it with an other wifi-router. No connection.
The next time i started the notebook with netrunner i had a wifi-connection. Rebooting … no connection …
It’s the same game, every third or fourth time it works.
I can feel your frustration.
It is definitely a bug. But from everything you told me so far I can only assume its a bug in the kernel or some network-manager setup.
Have you tried another linux distribution with the same kernel and level of network setup like KDE Neon for example?
Do you experience the same issue there?
