No - boosters are a poor solution you can do far better than that. But you do need to first determine whether your issues are wifi only or on the VM network connection.
Easiest way to do that is how I suggested. Connect a laptop/computer directly to the Hub with a Cat5e/6/7 ethernet cable and leave it that way until your wifi devices (phones?) drop out and then see if the wired connection is still working as expected
