After some search on net i found this post:
http://avm.de/service/fritzbox/fritzbox-7490/wissensdatenbank/publication/show/1636_WLAN-Stoerungen-bei-angeschlossenem-USB-3-0-Geraet/

Background:
The high magnetic frequency’s of USB 3.0 data transfer inside the cable or stick hangup the WIFI chips! It works like a WIFI JAMMER!!

DONT USE A ROUTER AS NAS! If it fails or overheat all devices are offline!! It’s a really big joke that most Manufacter sell devices without TESTING!! I call it Banana Hardware..

Ubuntu: Create USB Live System Stick for Live Mode or Emergency Help

For all Users, especially Newbies its VERY helpful to have a Rescue System on a USB Stick if a Major Update/Release Change fails or break the System.
