Right, after a lengthy (40min) conversation with customer services, the nice but slightly dim-witted lady uncapped my connection to what it "should be": a pleasantly surprising 14.5mbps. And then I looked at the sync speed on the extension socket...3mbps! So I connected it to the master (with the brand new faceplate) and once again it was 3mbps! The test socket result when connected came in at only 7mbps. What is going on!?
