And i was talking to another guy on reddit he told me the only way to get -27 power deduction is to have a dedicated coax that runs directly from adapter to adapter and adding any splitter will cause a it to go higher
So i fixed the problem. I bought a wcb6200q extender and did a factory reset on my moca adapter that feeds the modem. I now am getting -18 power reduction and 250 down
My laptop doesnt have a gigabit port dam.... I saw one guy on another fourm with my same problem but he had -27 tx power dbm but hes still only getting 600 mbps
That is my setup i think the problem is one out of two things the coax cable connecting the moca adapter to my modem has a short copper conductor and/or the coax from outside that connects to my room as a semi rusted copper conductor
