Could i get a speed increase

[unbiased]

Hi all im always on this site but rarely post but now asking for a bit of advice
Ive just had a problem with my phone line resolved, and it has actually made my downstream db lower than it was before
Ive always got a very steady 5mb connection with 46db downstream,snr between 5 and 7 since i had my line fault sorted a few days ago my db has dropped to 41 and snr is 11 to 12.
Does anyone think i could now get an increase in speed at all from this, is it worth ringing them and who would i ring?

Any help or advice appreciated, full stats are as below if of any help to anyone

DSL Link Downstream Upstream
Connection Speed 5021 kbps 796 kbps
Line Attenuation 41 db 19 db
Noise Margin 12 db 16 db

Yes you should be able to get 2-3mb more, you will have to ring Sky.
