This is not an Ethernet splitter as shown but a simple "power strip". The 8 1,2,3,4,5,6,7,8 son of the A and B of decision, are connected together to 8th son of C. This decision has no chance of working with Ethernet device. Can only be used in analogue telephony! For an Ethernet splitter it is imperative that either A 1,2,3,6 1,2,3,6 1,2,3,6 C and B or a C. What is 4,5,7,8 the only way to duplicate Ethernet. So this is absolutely not usable. I returned to the seller (shipping costs to my charge!) For a refund.
