W-lan - driver update don´t work

[Kamelkaze]

Hello guys,

i have a digitus dn 7042-1 which don´t work out of the box. Beware, i´m a newbie with Linux.
I followed the instruction in this thread (sorry it is german, but don´t find any other fix):
http://www.forum-raspberrypi.de/Thread-digitus-dn-7042-1-funktioniert-nicht?pid=59904#pid59904
I followed the steps and until i try this with root access:

Quote: sudo cp DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 /root

i get this message:
cp: cannot stat ´ sudo cp DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 /root ' : No such file or directory

No /root folder out there or is it a wrong path? In WinSCP i don´t see a root folder...

What did i wrong?

Best regards
