Can you describe how your network is setup (Internet provider, Internet router, switch if not using built in switch ports on your router), etc? Also, what is bridging your ethernet into Moca, are you using the pro as the gateway with ethernet connected to the pro? do you have fios or do you have a dedicated Moca device like a actiontec moca adapter acting as the gateway? Might be better to start a new thread rather than to crash this one unless you believe an external ethernet switch issue. In the majority of situations, wired ethernet is usually more stable than Moca.
