Over on the rpi forum some users have reported USB3 causes problems with the wireless network.

The use of a ferrite clip on clamp on the connection cable has been reported to be useful.

I don't know the manner in which these problems manifest.

Do a google search for "usb 3 and wireless networks", this is one of many results
