If not, please let me know and I can get it cancelled.
I'm very sorry that we didn't seem to be able to get your requested engineer time.

Down Atten has moved from 44 dB to 51.5dB and Up from 24.0 to 29.9.
Down Speed from 7215 (avg) to 162 and Up from 1025 (avg) to 444.
They then told me my two hours were up and PlusNet would need to contact me to re-arrange another visit!
Not too impressed as I am guessing PlusNet will not contact me for at least 24 hours and I am unlikely to get a visit this week.

Thanks for your time on the phone just now.
I've called BT on the off-chance that the engineer might have filed his notes back to Wholesale, but unfortunately this hasn't happened yet so I've not been able to book a further appointment. I'll try to give it another shot before I go home tonight, or it'll be first thing tomorrow morning.

I'll need to confirm later on that it's been booked in all BT systems.

Thanks for booking.
However, just come back from a meeting to find I have no sync at all (and have not had any sync now for over an hour).
Tried logging a call and was advised that if I did they would need to close my "intermittent" call (i.e. the one with the Engineer tomorrow).
Effectively down now until BT engineer arrives sometime tomorrow, that is, if they can fix it.

As I mentioned, I think we're going to have to wait for the engineer, but if you can try the test socket and your spare modem, it helps to rule everything else out.

Now stolen business line to test cabling between Cab and home. Already mentioned he has two hours and then he is off to Shperd's Bush. So I've got another 30 minutes fo his time!
Simon
NB
Figures on his kit, not mine. Att has increased, thus reducing by sync speeds when they finally fix it.

So where I have (and I have the stats) 7.5 Down now I have 3.6 Down. and Where I had 1024kbs Up, I now have 888kbs Up.
Attn is my worry - WHY has this risen from 44 dB to 50 dB Down and 24 dB to 30 dB Up?
SNR is roughly the same!
Stats below:

Did you ask the engineer why this might have been the case?
