Congestion/Contention/Fault ?

I have been connected with ADSL for over three months continuously at 7.04 Mbps with a profile of 6 Mbps. The PPPoA drops every three to four weeks, presumably to renew IP addresses. No internal wiring, connected to master socket, so no problems in premises, in line to exchange, or in the ADSL service.

BUT this last week evening throughput has been dismal, downloads almost impossible.

Took a survey on Wednesday:

0930 throughput was 5.89 Mbps

1100 throughput was 5.87 Mbps

1300 throughput was 5.88 Mbps

1500 throughput was 5.84 Mbps

1700 throughput was 5.88 Mbps

1800 throughput was 2.58 Mbps

1900 throughput was 2.44 Mbps

2030 throughput was 1.10 Mbps

2130 throughput was 0.53 Mbps

2300 throughput was 1.87 Mbps

 

All testing is with BTW performance test.

 

The 2130 performance is below acceptable standard by even the generous BTW standard!

 

I am on Inverness Culloden exchange which has no planned upgrade to infinity announced.

 

Surely this is either over-contention, major congestion, or a fault?

 

Can anything be done to persuade BTW to investigate?

are the btspeedtester results done wired or wireless?  did you try a new filter?

 

can you post adsl stats from your router please

Re: Congestion/Contention/Fault ?

BTW Speedtester is always wired - I have no wifi turned on.

Plusnet reports exchange has some 20CN paths outside planning guidance but still "within product guidance".

Re: Congestion/Contention/Fault ?

Hi CullodenMuir

 

I've been having the same problems as well for some time now.  Broadband speed can go as low as 1-2mb then strangely later on at night go up to 14+ mb (i used to regularly get 10 - 12mb).  The main thing is that the fluctuations in speed can be really random despite the fact that I'm connected to the master socket.  Like you, I've often wondered if there's congestion at the exchange.  I live in the Telford Road area of Inverness.
