Slow Broadband and Landline Not Working

Question

I recently moved into a new property (last November) and although the connection is often intermittant, the speed was great and way above what I was expecting (up to 18Mbps down).
We had some torrentially bad weather recently, and our line speed has dropped down to around 2Mbps down, and along with that our landline has stopped working. I get no dial tone, even plugged into the test socket (tried with and without the ADSL filter), when I call the landline from my mobile it rings and rings on my mobile, but no sound from the landline. Could this be related to the weather, or am I making a connection where there may be none?
Also does the fact I don't get a dial tone in the test socket mean it is likely a problem with the line outside of the property? And could whatever is causing the loss of landline also cause the drop in broadband speed? I have contacted BT a few times, the first time they suggested new ASDL filters, which I've attached with no luck, and they've now told me they'll send out engineers (at some point).

Answer 1

broadband can work with only 1 of the 2 wires conected but usually very slowly - just like yours
your attenuation up is greater than the down attenuation whereas normal is about half the down attenuation and with your current down attenuation you will never get 18mb more like 8mb
need to report fault asap or use the link
