Recently I noticed an update to libmenu or something similar and NetworkManager seemed to work much better. Then I plugged in my Ralink chipset adapter and the problem resurfaced within minutes.
I have both an Alfa and "Chinese" generic adapter with the Ralink chipset.
In summation:
Works fine all day with internal Intel chipset only.
Works for up to couple hours with the Alfa adapter.
Always faults within 2 hours with the generic Ralink.
Even faster when all three are inserted.
