Internet connection single connection speeds

Hi Everyone,

I have an issue that i've been trying to get solved with my ISP for almost 12 months now.  Their final answer to me is essentially this: "We acknowledge we can't guarantee our service anymore, and we will not upgrade our infrastructure as the NBN is soon to take over anyway.." (the NBN is the new national broadband network we are getting in australia...years away from my house however...)

So, here's my issue:

Multiple simultaneous connections, i.e, torrents, or a download manager, are great, every time.... i can achieve about 2.5 - 3.0 megabytes per second.  a www.speedtest.net result will be between 20 and 30 Mbit.  BUT, for single connection things, such as youtube, foxtel on demand, streaming music and video clips, watching online episodes of missed programs, itunes downloads, internet browser downloads etc... i can only ever achieve about 30-100kb/sec.

Obviously the bandwidth is there, as i could put on 20 downloads at 100kb/sec, and they will all stay at 100kb/sec, or i could put on just 1, and it's still only 100kb/sec.

I can't switch ISP's as the FTTH is the only thing available to me.  ADSL is 8km from the exchange, and 3G reception is not good enough here.  

I've done so much research and i don't really know how to word in technical terms my issue other than using terms like "single streaming downloads vs multi streaming downloads..." which doesn't turn up much..

Is there any piece of hardware, or configuration, i could use to try and utilize the speed i have available to me for basic things like browser downloads, itunes downloads, youtube, etc.. ??

By the way .. it's not a software configuration issue, i've used over 7 computers, mixture of mac, pc, windows xp, windows 7, ie, safari, firefox, chrome, etc.....

Thanks

Anshan, thanks for time, do you work for an ISP?

I need to respectfully disagree and clarify my question

1) The ISP has admitted it's not delivering, their solution is a 20% discount on my subscription
2) Once when I had ADSL concurrently running (only had a 1.5Mb link though) I used to A<->B the two connections (they were each connected on their own wifi router), and on exactly the same site, the super fast Internet that works for multi streaming downloaded at about 45kb/sec and the ADSL downloaded at 150kb/sec.  Pretty much almost exactly it's full uplink speed.  
3) You mention software, well Foxtel on demand is a pay-tv set top box... And they all are programmed to access the same server, but once again, on the cable, it takes 10 minutes to load 1 minute of movie, and on the ADSL, it streams on the go faster than the movie.  So how can that not be my ISP ??  Same hardware.  

Anyway, my question was, is there any hardware that would better utilize the connection for single connections??

I tried that glassnos test in the link above and it said there was too much noise on the line to be able to detect throttling.

Thanks again

Strange problem and I don't see a simple fix. Even typical bonding and link aggregation methods may not work for you. This won't help you with single streams, but for everyday browsing, you might benefit from increasing the simultaneous connection limits in your browser.

I stand by my response.  Did you try pingplotter to see where the bottleneck is?

The issue I see is that they're not traffic shaping, but traffic policing, and have set the level quite low.

On the other hand, they've left queuing/scheduling unregulated or at high settings. Ideally, the ISP would adjust the settings to achieve a better balance, but that is out of the customers hands.

There's no easy solution. One way around the bottleneck is to have a proxy outside buffering the requested streams, but most sources only create one stream at a time. You'd need an inverse multiplexer on the proxy to spread the stream into multiple sources. For this strange situation, it might be sufficient to connect all the outputs directly to a switch. Now all this could be done in software, but AFAIK, it doesn't exist, since other solutions are usually simpler.

You stand by your response ?

I have actually had 2 wifi routers running.




                                                                                                                         Router 1: (ADSL link speed 1.5Mbit)                      Router 2: (PPPoE FTTH):


www.speedtest.net result                                                                                1.3Mb   /   0.7Mb                                                    23Mb  /    1.6Mb

STB on demand plugged directly into router (No PC involved):                         Movie plays FINE                                                    Every minute it stops and says "please wait for more of title to download"

Download from www.cnet.com (same file using download manager):             156Kb/Sec                                                               2.4MB/sec (almost full uplink speed!)

Download from www.cnet.com (same file using browser download):              155Kb/Sec                                                               45Kb/Sec

Youtube 480p 3 Minute Clip (Same clip)                                                           Buffered fine, plays almost instant                          Stops every 3 seconds and buffers for about 10-15 seconds

uTorrent (same download tested by switching networks and resuming)         139Kb/sec                                                               900Kb/Sec




SAME HARDWARE, SAME SOFTWARE, SAME FILES, SAME USAGE.   How can you say it's NOT the ISP ?????

Clearly the second connection (which you say its not the ISP's fault) is the better speed, and SHOULD be working better, but the lousy 1.5mbit ADSL 6km from the exchange is the one that streaming everything perfectly fine.  Now do you stand by your response ??

I believe there could be some policing as described by inbox.
