First of all, thanks to the community for the support. My problem is this. I need to change the mac address of my wifi device but I can't. The model of the wifi device is TL-WN7200ND. I have only been able to change the mac address using ubuntu 14.04 by modifing the interfaces file: sudo gedit /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
pre-up ifconfig wlan0 hw ether AA:BB:CCD:EE:FF
-------------------------------------------------------------------
However, I did the same in Linux Deepin and wireless crashes after rebooting.
I have already tried with this also....
sudo ifconfig down
sudo ifconfig wlan0 hw ether AA:BB:CCD:EE:FF
sudo ifconfig wlan0 up...
The mac address changed, but when it tries to connect to the wifi hotspot it immediately turns back to the default mac address

I want to know why modifing the interfaces file in Ubuntu works and in Linux Deepin doesn't?. I want to modify the system to change the mac address in the booting proccess. Thanks I hope you can help me.
