Maybe I don't fully understand the information the tpPLC interface is giving me but, We have just had 1Gbps broadband installed. From my understanding as can be seen on the right the adapters have a link speed of ~ 600mbps , but when running a speed test I can only reach ~ 150mbps, All ethernet cables in the house are cat7 and the motherboards of the PC's are rated for 1gbps.

Any help would be greatly appreciated. Thanks !
