Using the WiFi functionality eventually the system get disconnected, and scanning won't work anymore.

This is well known issue, in fact it is stated right on download page for the device:

Quote

Onboard wireless module (XR819) has poor software support so wireless connection issues are expected

 

Here is early work for proper XR819 mainline support. Tests reports are welcome, to see if it is actually any better than vendor driver. I got reasonable speed using it and only problem I can see is that suspend doesn't work. Of course, developer tests rarely last more than a few minutes, so long term stability isn't known.

 

Note, I extracted pretty recent FW binaries from H616 Android box, which should be better than old ones, in theory.
