Thanks for posting here! When powered, a USB 3.0 port or device will generate significant broadband interference around the 2.4GHz band, as part of it’s normal operation.
This severely reduces the range of any wireless network adapter in close proximity to the USB 3.0 port through which the USB 3.0 device is connected, resulting in spotty performance and intermittent disconnects. Intel published the below white paper that talks about this issue in detail: http://www.usb.org/developers/whitepa…
Here is a link to another post where this same issue was seen by a user who mentions that connecting the dock to a USB 2.0 port on the system fixed the issue for her : http://support.plugable.com/plugable/…
Another option is to connect the Docking station to the wired network via the Gigabit Ethernet port on the dock. This way the laptop can be connected via the wired network when connected to the dock instead of depending on wireless for Internet connectivity.
Hope the above information helps!
