Profile dropped from 2.2(ish) to 1.3 on ADSL2

[#1]

What has happened to my profile? I live in rural Wales but have been getting a reasonable 2M throughput
for over 12 months now.
But things have slowed down over the weekend. Checked PN profile and its now
at 1.3. Nothing changed in premise (see below).
Had an electrical storm on Monday (19/05) which rumbled all day, so I did a graceful disconnect of router and
unplugged main phone socket.
Any chance of a quick look at line and a reset of profile?
Many thanks, Ian

Hi Ian,
Your line has fluctuated recently with sync speed and the SNR margin which has had an adverse impact on the DLM, your line has also been disconnecting intermittently.
Your line speed has dropped to it's lowest point today for some tome with a sync rate of 1.6Mb/s.

Do you have a test socket you can connect to?
Also, do you have any interference/crackling on your phone line?

Hi Chris,
many thanks for yr quick reply. 
The D/S SNR/Speed graph seems to confirm my routers
info with a usually stable SNR around 3-4 db.
I will try connecting to the test socket after posting this message.
So you will probably see the line go down again which might upset the DLM.
I have done a couple of 17070(2) calls today and they were both clear
as a bell .

If your line is stable once you're in the test socket we'll be then reset it and hopefully you'll see a speed improvement.

Ok Chris,
running via the test socket now, lets see if things settle down.

Hi Chris (Purvey),
any chance of a SNR reset? How is the line looking to you?
I think we lost power once over the weekend which may have upset the
exchange.
My router is currently showing :-

Which is not brilliant since I have been seeing a stable 3-4 db on the downstream until this recent problem.

I've just placed the SNR reset, it's seems to have gone through successfully, let me know how you get on.

Hi Chris,
thanks for yr. quick response today and the reset, seems to have come through
(see modem stats below). lets see how the line settles down.
