Got the unit from a friend, has the latest FW013. Problem is cannot achieve internet speeds much over 100Mbps, this on ethernet as well as 2.4 and 5Ghz. 1Gbps service to home, other devices on network see speeds of over 500Mbps on 5 Ghz and over 900Mbps over ethernet. Streaming services are unbearable to watch. Is this unit limited to just 100Mbps over Wi-Fi and ethernet?
