Connection speed issues MA2500D

I have a direct Coax run from our office to the living room. After installing MA2500D adapters on each end, the highest throughput I can get is 200Mbps from living room to office with frequent drops to nearly 0, and 300Mbps from office to living room using iperf. I updated both to the latest firmware, but no change. Do I need to reduce their TX power since there are no splitters? Also the switches being used on each end have EEE enabled, i have replacement switches that allow me to disable 802.3az on the way, could this be the issue? Pictures below, IPERF screen shots below are Living room IPERF set to server and Office Set to client. Screen shots of both MA2500D configuration and status pages as well..

Could you check the MoCA Link rate page. We want to make sure it is good.

From the screen shot. The MoCA link rate is very good. And there is no errors on the ethernet port.

Could you share the iperf command you are using? Have you tried -w and -P options?

I'll provide the full command as soon as I'm back in the office I appreciate your support with this. I'll also use the -d option to check bi-directional speeds. Currently the downstream/RX speed from the living room is significantly slower than the upload/TX speed which is very strange considering the adapters show a synchronous link rate. The download rate frequently drops to 5/10mbps with packet loss shown on the Ethernet interfaces, but not on the actual MA2500D coax link. So I'm lead to believe this is a compatibility issue between the Ethernet Nics in the MA2500D and my switches. Does GoCoax have a list of tested/approved switches?

After replacing the network switches on each end with SG105E models that can disable EEE / 802.3AZ the issues are resolved!
