This is in relation to a connection have in a small office, surrounded by big companies who have leased lines as BT have enabled the exchange but not the cabinet in the area.
Have two lines, one Talk Talk (LLU) and one through a BT reseller
The LLU has never been great (3meg DL) but the BT line has been in for around 2 years, maybe closer to 3.
The BT one has always been 10-12 meg, I do run regular tests and connection is hard wired.
Been stable until a week or so ago then was coming and going, phone line was going dead too.
Reported and BT engineer out and back up and running after a day or so.
I asked the reseller what the problem was and was mention of a pair......
The long and short, the previously 10-12meg ADSL is not only reaching 4.5 - 4.8meg, bad enough having to stomach 10 to be honest, what is likely to have happened here and anyway can get in back to where it was.
Any engineers or suppliers with knowledge care to advise.
Thanks in advance
