SNR reset

[#1]

Ever since I rewired my internal telephone sockets I have been getting a sync of around 7600-7900kbps (was approx around 6500).
being so close to 7968 I thought I would try dropping the snr from 6 to 5 so I could get a 7mb/s profile. It worked once but not had much success since.
The last few days our electricity supply has been off and on alot and last night I think this has caused the DLM to raise my target from 6 to 9.
BT speedtest attached. Is it possible to have a reset?
I have used 7GB of my 20GB allowance

Update: Have done 3 BT speedtests with the same result as above. Have also tried connecting using speedtest@speedtest_domain with the same result as below.
If someone could have a look I would be grateful.

Hi ID,
Sure I'll give that a go for you.

Thank you. Sorry to be a pain with something that is probably self inflicted.

[#5]

Hi ID,
Looks like that's taken effect now, a status check on your line is showing a downstream SNR of 6dB and a sync rate of 7840. I'll up your profile on our side to match, hope that's improved things for you

Hi Matt,
It hasn't as of yet. My router stats are back to what you say but the throughput is the same. Should I try rebooting the router? I didn't want to mess with it whilst in the training period.
Regards

Hi ID,
Do a reset via the router rather than unplug it, that should do it.

Still no dice. I have just got my spare router out. I will try it in the morning and let you know how i get on. I have got a new filter to try as well.
Thanks for all your help!

Hi Jo/Matt
This morning the line had gone back up to 9db. Still slow throughput. I setup my spare router on the main telephone point (No test socket unfortunatly). It synced at 2000kbps and for the first time the upload had reduced to 576. I couldn't get any pages to load though.
I had removed all telephones from sockets and changed filters. I am at a bit of a loss.
Just plugged the Netgear back in and got:

Think I am going to need to raise a fault

Fault raised. Ticket number is: 51095157

[#11]

Hi ID,
I can see the ticket's been updated and there's a request to check your wiring on there, please let us know if that makes any difference to the connection? It'll be the sync speed that changes, not the line profile or download speed unfortunately.

Hi Matt,
Spoke to Chris yesterday after I fitted a BT socket. The router is now in the test socket and all extensions isolated. He seems to think its a line card fault.
Hoping its fixed for the weekend

[#13]

Have you seen the update on ticket 51095157 from earlier today? it looks like Chris has asked you to do something...

[#14]

Just rang and spoke to Chris. Nothing has been added to my ticket today. He asked for a TAP3 test yesterday which was done.
He said one of your guys will ring me back after getting on to BT.
Cheers

Could someone chase this up for me please. A second reset was requested by the engineer who visited yesterday morning.
I have a feeling that will not fix it, so I am eager to get onto the next course of action.
