Are all of your 6 players on the same Wifi router?

In my two Radio set-up, each is connected to a different Wifi access point. The PcP is connected to the router via ethernet. This might explain why I have more more frequent drift if one of the routers is busy dealing with some other device.

Does anyone have any suggestion on the Synchronize settings? I see a Network Packet Latency (ms) adjustment. Perhaps that might help?
