Slow FTTC?

Hi all,
I took FTTC with Aquiss as they seemed to be the best option, and Martin has been very helpful with his customer service.
THis issue has apparently been refered to BT a few times, with no fault found.
However this is what i experience....
When using Usenet or a multitthreaded download i get like 4.5mb/s which is correct ( synched at full 40mbit)
However when downloading via http or browsing the web, it is incredibly slow!
Downloaded the 100mb test file from aquiss a few times and....
maximum i get is 1024kb/s which is obiously far from unacceptable!

1. Best Effort Test: -provides background information.

Download Speed
9223 Kbps

0 Kbps 38717 Kbps
Max Achievable Speed

> Download speedachieved during the test was - 9223 Kbps
For your connection, the acceptable range of speedsis 12000-38717 Kbps .
Additional Information:
IP Profile for your line is -38717 Kbps

This is the BT Speedtester,
And

Thats Thinkbroadband Quality meter, which shows some loss at the top.

I was browsing via my 3 dongle earlier, and this is faster web browsing than my 40mbit connection!




I was wondering what suggestions or ideas anyone has here?
My thoughts maybe a long a faulty OR modem or faulty pair?
Cheers

Couple of obvious ones, are you connected via wifi or cable, and is the router giga or fast Ethernet (if fast Ethernet any other machines connected to same router?)
What is the OS of the machine? as it looks like multi threaded is OK but single thread can't run that fast, have you looked at the firmware of the router (what make/model?)
If running XP have you checked rWIN?

Thanks for the response.
Mixture of wired and wireless, same on either.
Router is 100mbit, buffalo whr300 v2, running ddwrt firmware, several machines connected to router, wired and wireless.
All pcs are windows 7, i have the same issue on my ipad and my htc desire
Cheers

i had a similar problem but it actually turned out to be windows took my 1gb ethernet cable down to 10mb make sure that this is not happening i would also check your router settings as my buffalo sometimes plays up as well

mentions the full 40mbit from usenet, so it's not the network connections in the home.

Your download bar on the speed test was red, as you got less than the minimum acceptable speed. This should confirm it as a fault to BTO and your ISP should be over them like a rash to fix it.

Good luck.

Is it time-of-day related? If so, is it Entanet-based? Does it happen with the native firmware in the Buffalo, as someone with the gig-ethernet Buffalo which apparently comes pre-installed with DD-WRT had trouble until they flashed it to native?

Just to clarify, looking at your opening post as a whole, would I be right in thinking

all refer to Bytes not bits. There is a difference of a factor of 8! Though even as bytes, it is slow I agree - but within the possibilities of ISP congestion. Hence my query as to the underlying ISP. What does speedtest.net say the ISP is?

The customer is with ourselves. Reports have been from all times of the day and even when the network is not busy.

We were leaning towards the router at the start, however customer has reported that they have tested directly from the OR modem and report similar issues.

The fact he is getting correct speeds with multi threaded downloads but poor speed on single thread, does scream out to be network related and to the router, but connected directly on Win 7 could point to the modem, we have had a few of these with all sorts of odd ball issues, of course BT won't admit to any issues with the modems!

Unless they start smouldering like the Huawei VDSL modems...
