i have alot of problems (Raspberry Pi 3b+ 4.19.37-v7+) with freezing networking connections during a ssh session or when I copy a file from windows to a samba share on the pi. The file transfer and the ssh session freezed completely for a couple of seconds.
My other Rasperrry Pi 3b didn't has this kind of problems. Everything works flawlessly. It has an older kernel version 4.14.98-v7+ installed.
I don't have a clue whats going on with the pi and why the network stucks, network cable, switch an setup is configured right. What can I do ?
