If I make the same specific test with from the driver from marvel intranet, is working (maybe because the firmware is more recent ?) but anyway the general stability with the driver is poor, I get frequent kernel crash, I see at [1] that this driver is based on android and I've personally to admit that mwifiex driver solved the stability side but unfortunately introduce a regression on wpa-none. With mwifiex backport driver of Linux 4.1 is not working, I mean the link seems to be established always even when the password is wrong. I saw on older thread on linux wireless with similar issue but more related to fix ibss-rns, but with my test ibss-rns never worked with mwifiex as with intranet one, so I think will be more important fix the regression with wpa-none.
