Successfully installed a pair of the 2.5 adapters and they work perfectly with no configuration. The third adapter I have added (which branches from the same 6-port gocoax splitter as one of the working adapters) will not connect. The moca light on the adapter flashes rapidly and the computer it is plugged into has a self-assigned IP. Is it possible that something is wrong with the coax cable for this third adapter? Or do the adapters all need to be on same firmware version, anything like that? edit: is it expected that the full quantity of twelve adapters can be plugged into the same network without configuration or does something need to be changed in the settings? thank you!
