    I just noticed that when I plug in my PNY Turbo Plus USB 3.0 flash drive into the right side USB drive of my late 2013 15' MBP, it disables my internet connection. As soon as pull the flash drive out of the USB port my wifi works again.

    I plugged the USB into the left USB and the wifi works perfectly. Does anyone else have this issue?

    That's an odd issue, I've not seen or heard anything like that before. Sounds like something is up with the USB port on one side of your MBP.

    If you plug any other USB device or cable into that port does WiFi also disconnect?

    Sounds like interference generated by a poor connection, possible the USB port connection itself but possibly an internal fault with that port.

    I plugged in my iPhone with that port and no issues at the moment. I'll be trying another USB once I get back home. I also have a genius bar reservation for tomorrow so we'll see how it goes.

    I'll keep you all updated.
