However, some time cost
1. complete disassembly of the laptop (module can be reached, but 2 fixing screw located under the casing)
2. uninstalled any old drivers for this.
2 new drivers (Intel) for Bluetooh & Wireless installed
Restart ---> only set up the Wi-Fi's and sign the Mouse.
Speed is much better compared to the old module (had only one frequency)
