More specific?
The BM/S5 doesn't have wifi. It is possible just to install any USB-Wifi adapter at the back of the BM5.
Enter the service mode and you'll get the windows desktop. Install then any adapter you like.
Make sure you copy the driverpack from the wifiadapter to a USB stick and copy them to a new folder on the data partition.
But a warning before you start with the wifi instead of the standard cable connection. It takes a lot more time to copy albums to the harddrive.
