That's better but not as much as you should be getting. How is your router connected?
Is it plugged directly into the main socket in the wall or through an extension?
Whichever way it's connected try removing the front cover of your main socket, just two screws and it pops off. If it's a modern box there will be another socket inside, try connecting to that and see what your speedtests are like.
If it's an old box like mine you might want to try hard wiring wires 2 and 5 (I think) from your roouter/extension to the socket. It worked wonders for me.
