my line speed has halved to ADSL speed in a week


[link to this post]
 
Hi Guys
I have "superfast Broadband" fttc but cabinet is a mile away. I always previously got a rubbish 12-15 meg download and just under 1 meg up.
In the last week or so this has dropped to 5 meg down and 0.6 up - I used to get more than this on ADSL.
my stats are as follows.

Having trouble figuring out which are the connection speeds and the max speeds.

Can you confirm the actual connection speed figures, think it may

Connection Speed 9999 Kbps down and 921 Kbps up
Max Rate 21388 Kbps down and 1137 Kbps up

The Max is still showing the old figures, but looks as if the line may have been banded, i.e. Openreach DLM fixing maximum speed to stop line flapping around. Without a set of previous U? D? band figures hard to say if the line has got worse or not.

Hi

I previously got 6meg sometimes 7meg on ADSL.

With 9999 Kbps sync you should be able to get 9.5 Mbps speed tests, so if tests are still well below that suggests maybe seeing a fair few errors, which would also be supported by the way it seems that banding has been applied.
