Research direction
Start by reproducing the RT5370 connection drops on the listed Raspberry Pi 2 Model B systems and kernel 4.19.42-v7+, then collect relevant dmesg output and compare behavior with the RTL8188CUS dongle. Check whether the reported wpa_supplicant downgrade changes the result; done means a stable Wi-Fi connection without drops every 5–10 minutes.

Description
Describe the bug
Got 3 Raspberry Pis running. All having Raltek RT5370 chipsets. Having unstable connection for a few weeks. I recognized because a webapplication is running which goes dark when it loses the network connection. So I recorded a 15s loop ping and sometimes I can't reach them.
After replacing 2 RT5370 with RTL8188CUS usb dongles connection isn't dropping anymore.
To reproduce
Use RT5370 chipset wifi dongle to connect
Expected behaviour
Stable wifi connection
Actual behaviour
Unstable wifi connnection. Dropping and reconnecting every 5-10 minutes.
