Are there any working extensions in the flat ? Have you tried plugging into the test socket behind the lower part of the BTmaster socket, in order to eliminate any internal extension wiring and also the faceplate it's self, ? As said give it a day or so , if no improvement then try the above ,
also have you performed a quiet test using a corded phone 17070 option 2, ?
if there are any noises such as crackling or other noises that are odd present there may be a fault with the line itself
As for your speed, that is currently being restricted by the current Bras IP profile which is set by Bt's woeful DLM Your connection has probably been interleaved which won't help with getting max speeds,
Also the Upstream sync appears to be capped, ask your isp to uncap it , you may get a 1mbps usable upstream rate then ,
If the IP profile doesn't increase then i think the ISP can get it reset , or maybe even disable DLM altogether ,
But IMO getting around 13mbps throughput with a sync of around 14.5-15mbps with a short line, and attenuation figures like yours isn't just fine at all, fine for who the isp?
