Removed the bluetooth daughter card and this solved also my ethernet issue:
infact under Network Manager there was only Ethernet/ "Device not managed".
In fact only wireless network was working. Wired network never worked.
Before removing BT daughter card NetVM dmesg (copy enclosed) reported a
strange relation between bluetooth and ethernet:
[ 6.963166] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
After removing BT daughter card wanted to check if anything changed with
ethernet and YESS, now it is working.
(Attachment dmesg.log.txt is missing)
