USB 3 and Wireless Connection
RE: MBP Retina 13" Mid 2014 - Right side USB 3 port
Got an intermittent problem when plugging in either one of my external drives* to this particular port. Sometimes I lose my wifi connection. As soon as unplug from that port the wifi will immediately come back. This problem does not happen with the USB 3 port on the left side.
Do you think a SMC reset would be in order? Any thoughts would be appreciated.

Possible wireless interference from your USB port / drive.
A nice writeup on why this is happening. Sounds like you already figured out a way to prevent it.
