Broadband speed drop since line fault repair

Question

We have recently had a phone line fault fixed but after more than 3 days  the broadband speed has been lower than it was during the fault and less than half its original speed.
Pre-line issue downstream was around the 16,500kbps with some drops down to 13,000kbps. The line developed a fault which started causing dc's and the phone line became noise with constant cracking and rustling sounds which turned out to be a damage connector causing water to corrode the cables, during that time when active broadband speeds dropped but while connected gave 9726kbps download and 888kbps upload, the phone line was fixed on friday the 15th of January and the phone line itself is very quiet, better than its been in maybe years, no noise that i can hear at all. However the connection dropped out during the night after the line was fixed and came back at 6652kbps down and 440kbps up, it remained at this speed for atleast 3 days then the router reconnected at 6652kbps down with 888kbps up were it remained until this morning, the router reconnected again at exactly the same speed.
I can understand it dropping originally due to the fault but has had over 72hrs connected but the speed has not increased, infact the speed is slower than with the fault which makes very little sense but i suspect is something to do with the noise margin, I include router and btw reports. Hopefully I can get some help with this.
Thanks
Jon

Great just shy of 3days connected I appear to have had another sync on the line, still no change to downloadspeed but yet again an upload speed increase, Obviously the exchange is trying to resync but it seems my download speed is stuck. This was the 1 and only connection change, should have posted the stats las tnight to show 2days 12+hrs before I went to bed
