Aug 4, 2015 11:09 AM in response to 1Sby lllaass,★HelpfulUsing a 5 GHz network will eliminate the wifi problem. However, BT is still 2.4 GHz and will not change the problem.
Do you have a late 2014 Mac Mini?

Aug 5, 2015 3:52 AM in response to 1Sby woodmeister50,USB 3.0 is notorious for interfering with WiFi and Bluetooth on
all platforms.
Not all drives and devices are built to standards to prevent interference.
They may meet FCC radiation requirements (which through the test set up
can be manipulated to some extent to allow the device to pass) but still
radiate sufficiently to disrupt other communications of which WiFi and
Bluetooth are particularly vulnerable.
You could try a higher quality, longer shielded cable and locate the drive
further from the computers. A last ditch, get a metal USB3.0 drive enclosure
and swap the drive.

Aug 7, 2015 12:31 PM in response to woodmeister50by 1S,Update
I temporarily replaced the Fonera v2 router with an ancient, original Time Capsule and did some more tests.
Apparently the Mini needs a Line-of-Sight (i.e straight line) connection to the Time Capsule whenever the USB3 disk is connected !
With a LoS connection, the WiFi and BT work fine - good enough to max out my 30Mbps internet connection.
Without a LoS connection and a disk attached, WiFi slows down considerably or drops out altogether, and BT becomes sketchy again.
Shutting down the disk, will restore the WiFi connection, and BT performance when using the TC.
But when using the Fonera router, WiFi will still be severely hindered until they can "see" each other directly, while BT recovers when the USB3 disk is shut down.(The Mini and the TC or Fonera are merely 20' / 6m apart !)
