New customer here. Is there a method for tweaking performance? I have a simple setup using 2 WF-803M adapters. 1 adapter connected to a gigabit Ethernet port on my router, the other end is connected to a gigabit port on a switch. There is 1 moca rated splitter in line, outside in a box. Total coax length is less than 60 feet. No other equipment is connected. I'm seeing data rates around 200 Mbps. About 1/10th the maximum advertised rate. Is there a way to boost performance or is it auto negotiation only?
