Have just been upgraded to a roadside cabinet with ADSL2+ in the last day. 


I'm on the full speed telecom adventure 20gb plan. 


I thought I'd try out a torrent to see how fast it goes. I started the torrent, and the speed went up to over 1000kB/S in a few seconds. 


But, then it quickly slowed down to around 10kB/S.  Occasionally the speed spikes up to around 200kB/s but mainly it sticks to around 10kB/s. 


I tried restarting the torrent, and every time the speed goes very high for a few seconds then drops back down to this 10kB/S . 


Why could this be happening? It is only since I was connected to the new roadside cabinet.


Here is a link to speedtest.net results for my line...

Try change your port number and turn on encryption.

It could be a couple of things, one being that I believe Telecom has traffic shaping on torrents so that may be slowing it right down, the other is that a lot of torrent clients incorporate their own traffic shaping so that if you arent allowing a certain amount of uploads on your torrents then they reduce the amount you are allowed to download.

As mentioned above, try changing the port number you are using for torrenting. This can confuse basic traffic shaping as it usually uses the port number to work out what type of traffic you are using. Just try not to set it to one that is reserved for other protocols as this can hamper certain things on your computer.

Reserved port numbers are listed here. http://www.iana.org/assignments/port-numbers

Have you restarted your modem?
What are your modem sync rates?

I would not use torrents to test my lines speed, there are just too many other factors involved. What speed do you get when you download itunes?

Before the new roadside cabinet change, I'd consistently get around 850kB/s download speed on a torrents. This was very stable too, and there would be very little fluctuation.

Now, I've restarted the modem, changed the utorrent ports, changed encryption but problem is still happening.

I tried downloading itunes , and this was downloading at a blistering 1400kB/s.

Modem sync rates are good, here is from my routers webpage...

Download...
Data Rate(Kbps) 17866
Noise Margin 11.9
Attenuation 0.0

Yeah, i used different torrents, all with high seed counts. The strange thing is that I get superb transfer rates for a few seconds, before falling right back down. Then, get the old spike up to a few hundred kB/s.

Is this what shaping looks like in action?

I don't think it is related to network overloading because the speed slow down is extremely predictable (a few seconds after reaching peak speed, it always dives down to around 10kB/s).

Oh well, doesn't really matter i guess. My webpages load quickly at least :)

Torrents are a horribly inaccurate way of trying to measure a connection speed.

Have you tried downloading a large file from another source such as iTunes or Microsoft? If you get the same issue then there could be an issue with your line. What are your sync speeds and line stats?

Right now you've given no information that could be helpful in diagnosing an issue if you do have one.

Thanks sbiddle, i'm not sure what you mean I have not given enough information. I've already given the speedtest.net results, the modem sync speeds, the itunes download speeds.

What else do you need?

What brand/make/model modem do you use? It may not be able to handle the number of connections?

I tried two modems. The first is a fairly new belkin F5d8635, and the other is a dynalink rta1025w. Both of these worked perfectly before the new roadside cabinet. Neither of them works now.

Wouldn't the number of connections would be the same regardless of speed though? Perhaps I could reduce the number in the torrent client.





Anyway, doesn't matter I don't use torrents too often. Just web browsing seems to be very data heavy these days.

Ahh, I found a solution.

Every so often utorrent asks me if I want to update to the latest release. I always just click yes, since there has never been a problem before. This happened last week sometime but I had not used utorrent much lately.

Just on the off chance, I reverted to the older non-beta version of utorrent. This , fixed the problem. Torrents are super speed, whizzing along at 1.6MB/s, and no slow downs. Smoking!!
