I strongly recommend that you re-install the drivers needed for the adapters. You can tell which of these devices need drivers by going to “My Computer”, right-click on it, select “Properties”, click the Hardware tab then click on the “Device Manager”. When something says “Unknown Device” or a yellow with black exclamation mark shows up, it means that a driver has to be installed. You can download and install these installers from your laptop’s manufacturer website by looking up your model compatible to the drivers.
