Today i was touched by a Bug of my fritzbox 7490, after installing a USB 3.0 Stick as NAS the Wifi connect was broken to all devices!
After some search on net i found this post:
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..
