I was not able to stop wifi turning itself back on in FW 2.14 even after reinstall the FW, when starting the himedia the wifi starts by itself, the wifi then somehow interferes with the lan connection and the network performance is terrible when both wifi and lan are on.
This is an old problem and I think himedia are ignoring it and it will never be fixed.
By the way the problem eexists with fw 2.14 on q10, q5pro and q30.
Had to go back to FW 2.12 where turning the wifi stays off.
There is a problem in the 2.14 fw
