XPS 15 - 9550 with TB15 docking station, problem with LAN Driver,s, & USB

Dear Sir,

I use a  XPS 15 9550 machine with a TB15 Docking,  I have installed all your new drivers as stated on the website with regards to  TB15 and xps 9550, but after rebooting the machine i get all the connections but within 2 - 3 minutes, only dispaly remains, rest all connections, LAN, Audio, Camera, wireless dongle usb fails, and i have to restart the machine.

I has become the most troublemost situation wherein we cannot work like this. Wheneever we call yur help desk for the same, they always avoid this situation, by suggesting to transfer the line to somebody else and then the other person also does the same.
