I wonder if anyone could advise on a big problem I've encountered with download rate.
First things first:
I usually sync at between high 7000's and 8128.
SNR between 6db and 8db.
Router connected to filtered faceplate.
I have tried different routers and different computers connect directly to the router (ie no network or extensions)
My download rate has been at or about where it should be, ie above 6000 as indicated by tbbMeter and BitMeter (IP PRofile 7000).
At the end of April the download rate suddenly dropped to about 3000 and has stayed there ever since.
Beginning of June there was a line fault, which has been fixed.
After download rate drop:
Speedtest result at 10AM indicated IP Profile of 6500, sync = 7936, downrate = 3111. (48%)
After line fault was repaired:
Speedtest result at 9AM indicated IP Profile of 6000, sync = 7072, downrate = 2307 (38%)
The sync has dropped as the snr has increased, which I am not concerned about, but the download rate has remained a long way off the IP Profile
It 'feels' like the connection is throttled or restricted in some way.
The connection behaves as it did before,
ie when using UseNet download rate climbs quickly to max and stays there, only now the max is around 3000 not high 6000's.
ISP has indicated 2 things:
1. that there could be congestion at the exchange.
There was no gradual drop in rate. One day normal, next day poor.
This speed restriction is a constant feature, it does no worse at any particular time of day.
I find hard to believe that my exchange would become congested 24/7 almost overnight.
2. BT have said speed is acceptable and refuse to do anything.
Well they would, it's easier to do nothing.
And the ISP don't appear prepared to do anything either.
The advice needed:
Why has my download rate suddenly dropped by 50-60%?
How can a degradation in service of this magnitude possibly be considered acceptable?
Surely there is a problem if the datarate is so far from the IP Profile?
Is it normal for such a large and permanent drop when everything else is as before (sync,snr,IP Profile)
If I had always received this download rate I wouldn't be bothering you but this is a huge drop in service level.
Sorry it went on a bit, any help or advice would be most gratefully received.
