Thanks for posting! I’d be happy to help with your docking station.
You used the term ‘lately’ when describing the behavior. Did this issue just start happening or has it always been an issue? I ask because it may help determine if some recent environmental or infrastructure change may be causing the issue. Since the issue happens over time it sounds like there may be some outside influence on the reception. Has anything changed recently in terms of the network infrastructure or how things are arranged on your desk?
Pending that information, one quick thing to try is connecting the dock to a different USB port on your system to see if that changes the behavior. According to the specs online for your system there are three USB ports in total. Can you try connecting the dock to a port on the opposite side of the laptop to see if the behavior changes?
Let us know the additional information and the results of trying a different USB port when you have a moment and we’ll go from there.
