I have 40mbs internet bandwidth (speedtest) available through my net gear router. When i plug into the TP expansion plugs the bandwidth available reduces proportionally to the inter plug bandwidth. For instance; an expansion plug close to the primary plug will show 200mbs on the data rate page and that plug will get 35mbs of internet bandwidth from the router (Speedtest). An expansion plug far away from the primary plug will show 50mbs on the data rate page and that plug will get 8mbs of internet bandwidth (speedtest). I am surprised at this degradation given the data rate between the plugs is always over 50mbs. Could it be that the “interference” that causes the TP inter plug degradation also causes internet degradation ?

Any views on a fix ?
