Slow downloads

Hi. I have been experiencing slow downloads on zen connection for last few months.
No matter time of day, no matter where I download from, even test files from TBB, download speed is 3-4 MB/s, where from steam for example its always 9MB/s.

I know downloads from steam might be using multi threading, but that is not the case.
The problems is I cant hit anything abode lets say 4-5 Mb/s when downloading from websites. I have been in touch few times with them and they dont see a problem. Well I do because like I said I cant go above speeds mentioned where my sync is 80mb/s.
I am on zen llu.

Is there anything else I can do or anyone else experiencing the same?Some speed test for you :

I'll try again (this time post in right area):

I would suggest setting up f8lure/thinkbroadband monitoring - if the line starts to "bow" at peak times there is a good chance the LLU is reaching maximum capacity at peak time.

It all set up pal. All my graphs looks perfect every day.

What is the spec of your computer? At speeds above 30-40Mbps older hardware can struggle to cope with fast download speeds like that, it could be something like this rather than your computer... Ultimately if you can stream at the full whack speed it is unlikely to be exchange congestion. I also doubt Zen have contention on their peerling links but it is of course possible.

Cant be Pc,, its middle range pc upgraded every 2-3 years

If your PC was the problem, how would it handle a gigabit LAN?

Anyway guys I have been told again by Zen there is nothing they can do, everything is as it should be. Ok then until April.... but the best is I keep sending them emails to customer services and asking, how much would it cost me to leave for example, and no answer for days...

Your graphs are perfect.
You can stream without issue.
ISP tests are okay.

The obvious conclusion is hardware issues .

( Or an antivirus program that is badly configured or corrupted, or conflicting with another security program)

Connect another PC or laptop to your router and see what happens.

Its not obvious because thats the first thing I did. I checked on my pc and 2 other laptops. Its the same...

Exchange take up? Just a guess.
