Loss of speed on my long line

My  speed has been very good (acceptable only) over the festive season (1.2 to 1.5 ) and now is awful ,no good for Skype and i player now Have Plusnet done something to my line ?? since last week ?? and why has my profile gone to .5

1. Best Effort Test:  -provides background information.
Download  Speed
0.39 Mbps

0 Mbps 0.5 Mbps
Max Achievable Speed
Download speedachieved during the test was - 0.39 Mbps
For your connection, the acceptable range of speeds is 0.05 Mbps-0.5 Mbps.
Additional Information:
Your DSL Connection Rate :1.98 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
IP Profile for your line is - 0.5 Mbps

Re: Loss of speed on my long line

I assume your router dropped its connection with the exchange, perhaps due a burst of noise on the line, and reconnected at 700-800kbps giving an IP Profile of 500kbps (0.5Mbps). Subsequently the router has been restarted when the noise was not present and synced at 1.98Mbps. This will give an IP Profile of 1.5Mbps, but on 20CN it can take 3-5 days to work its way through the BT and Plusnet systems.
How long is it since your router was restarted?

Re: Loss of speed on my long line

If you have or had some sort of fault, such as a duff filter, giving disconnections as you describe, there may have been a medium-term (ongoing) slowdown of your line.  Do you know how to get the down and up connection speeds, attenuations and noise margins from your router? Those should tell us.
