Hi there,

Is this 2.1 doser going to be kept separate from your P4 system?

If so, then WiFi setup can be done. In which case you should run a continuous ping command for your doser using Windows Command Prompt. For that you will type-in ping -t (Doser IP address here).
Look for any connection drops and see if it is a wifi signal issue. Otherwise, assign a Static IP for the doser and see if the issue persists.
