since my new installation of netrunner 20.01 i have the problem of very instable wlan and bluetooth connections.
The wlan-connection is asking me every 5 minutes or so for the password. And the the bluetooth-connection is very instable as well. For example: when I have an audio-connection all seems to be fine for some minutes and then the connection is going to be choppy or so …
This is a problematic chip that is known to have issues with the linux driver.
What you could try to do is activating backports and installing the newer kernel in backports.
Also try to add this option to the driver and reboot to see if it helps:
echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
Sorry if i’m asking again, but i’m not familiar with this kernel-stuff. Which packages do you recommend for me? In the momennt it is working the kernel 4.19.0-12amd
After activating the debian buster backports repo please update your package list with sudo apt update
You can install the packages. linux-image-5.8.0-0.bpo.2-amd64
& linux-headers-5.8.0-0.bpo.2-amd64
For Kernel 5.8.10
The terminal command sudo apt install linux-image-5.8.0-0.bpo.2-amd64 linux-headers-5.8.0-0.bpo.2-amd64
should suffice.
After that please reboot.
Note: If you have virtualbox installed make sure to update it from backports otherwise the dkms virtualbox package might display an error and virtualbox will not be usable with the newer kernel.
You can use sudo apt install virtualbox-dkms with backports activated to update it.
Can you try with activated backports to upgrade the firmware-linux-nonfree firmware-linux-free
packages. I hope that makes it work more stable after a reboot.

Make sure to have the complete backports buster line activated:
So the source file in /etc/apt/sources.list.d/debian-backports.list should look like this
deb https://deb.debian.org/debian/ buster-backports main contrib non-free
We don’t ship with contrib and non-free by default so that needs to be added manually for now (I merged it in master so the next ISOs should come with it added by default)
After checking this please refresh your packages list with sudo apt update
and try installing again sudo apt install firmware-linux-nonfree/buster-backports firmware-linux-free/buster-backports
Hope that works now and you can test if it fixes the issue for you.

Leave the firmware-linux-free package then. I thought it also was updated in backports but that is not the case. So only update the nonfree firmware package.
Ok, thank you. I can get no improvement, so I think I have to live with the bad performance. Or do you think there is another way to solve this problem?
Over a distance of 2 meters there is no continous audio-signal possible. At a distance of 50cm the audio connection is stable. I checked the connection to the bluetooth-reciever with another notebook over the distance - no problem.
That is weird indeed. Sadly the bluetooth chip and driver is proprietary. So as long as it does not work on any other distro better I don’t know what to do to improve this situation.
