It seems like it is happening if i try to download docker images, or apt upgrade

[MightyMirko]

Ubuntu was installed to usbc ssd and was sharing usb host with avm 860. Now i copied ubuntu to internal hdd and it seems to work fine :-)

Can you install wavemon for testing?

$ sudp apt install wavemon
$ wavemon

What are the link quality and signal level numbers?

Is the adapter in a usb2 or usb3 port?

That makes sense. Running a system from a drive plugged into usb3 is not always reliable. USB3 is not mankind's great invention.

I see wavemon now. You have a solid, strong signal and should be getting good throughput numbers. Hopefully it is stable for you with Ubuntu installed on an internal driver.
