Service Degradation

I've just been trawling through my SamKnows reports because I felt that there was some degradation of the service. It would appear than my latency has increased badly.
It seems that i've gone from 17ms June to Oct, 10-12 ms latency Oct-Feb then down to 7-8ms during Feb to 16-17ms during April/May and now 23-25ms !!
Download speeds have gone from 44mb June to Nov, 51mb Nov to May and now down to 44mb again.
Upload speeds have gone from 18.5mb June to March, 16mb March to mid May and now up to 16.5 since mid may.
Having had it take over 9 months to get my latency down after a series of power cuts during the winter 13-14 and a bit annoyed that i#s gone back up to a very high level.
PN ... can you see anything wrong at your end ? Any suggestions as to what the the issue might be ?
Thanks ... Andy

Your currently on a G.INP profile which may account for the higher ping times if your using a ECI modem. In terms of speed the profile on our end is set incorrectly so I've changed that now and you should be getting closer to 50Mbps.
@tijara33
Your line is also on G.INP at the moment. Are the ping times still higher?

Thanks for the prompt response Mathew. Yes, my ping is 2x what it was & I have an ECI modem so I guess that unless I change either my modem or my router, I'll have to put up with it??

Your issue is separate. Interleaving has been added on a high level on your downstream which is why your ping times have gone up.
@tijara33
Openreach are rolling a fix for the G.INP issues although I can't commend on when it will be done as I believe it's a gradual roll-out.

Ahh .... I have a Daytek modem and currently am not running the G.INP firmware. Now i know my line is G.INP enabled i'll upgrade and see what happens ... thanks.

DLM will have added Interleaving on a high level if there's been a high amount of errors on the line. There's a chance DLM might drop it if the errors go away but we don't control it nor can we overrule it.
@AndyHamp
I think that should do the trick as other users have reported upgrading the firmware fixed it. Let me know if it's still problematic.

Not seen any real change to the upload/download speeds but not unhappy with that that as the latency is the biggest factor for me.
Download speed achieved during the test was - 43.01 Mbps
For your connection, the acceptable range of speeds is 45.74 Mbps-57.17 Mbps .
Additional Information:
IP Profile for your line is - 57.17 Mbps
Upload speed achieved during the test was - 14.15Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps

Is that the Vigor 130 Andy H? If so I might as well go ahead & purchase 1. Is it just plug in, switch on & wait, like the BT ECI modem? Is it easy to update the firmware?

It's an 2860, i have one because i need the VPN capabilities for work. It's nice, but not cheap and not that easy to configure but great in terms of stability and reliability. Basical config is easy via it's quick start wizards and i had no problem configuing the VSDL.
The 130 is a very basic model, i'm sure capable, but i doubt it will support G.INP or vectoring anytime soon.
