I recently have had an 85 mbps powerline adapter, and i was getting speeds of 300kbps whilst downloads, i now have bought a 1000mbps netgear PL1000 powerlines and yet i still get 700KBp which is awful, the powerlines are not plugged into am extension cable however there is a plug next to it that powers the extension cable, im not sure what to do as im still getting 700kbps with 1000mbps powerlines ;(
