Had this problem for a while but I have just changed ISP so thought that mixed with a new router and laptop at the same time might have helped it, when I pop the ethernet cable in then I get full speed uniterrupted, but with wireless i get this pattern constantly :confused:

Any ideas?

is it computer and router talking via wifi to stay connected?

:confused:

During the time shown in the graph attached above the connection is still shown as active but if you try to click on a webpage its on a go slow. I thought it was maybe some inbuilt security into the router and it was thinking due to the number of incoming connections that it was getting hacked?

Sorry, but what do you think is odd about that pattern?

That could be anything really, so Ideally I'd need to know what you think the problem is and what exactly the behaviour you're getting is.

To me it looks like it starts off slow and speeds up which is what I would expect from a torrent connection.

Oh also, what is your router and software version on it?

Thanks

Mark, that pattern is totally wrong, If I run with ethernet on that particular torrent my speed, within 15 seconds maxes out at 1.3Mb/second, and stays constantly along the top of the screen till that torrent is finished.

At the same time, in the troughs shown in the graph all my nework activity dies a death.

the router is a sky homegrown branded Sagem F@st 2504 with Sky Latest firmware 1.9 and the updates are automatic.

It depends on the methods used by the transmitting layers as to how things run.

What I'm asking is for you to describe what you expect from the torrent and compare that to what you're getting.

A plain Ethernet (over wire) has very different characteristics to wireless, so I'm just trying to attain what was happening when you ran over wireless before you hit this problem.

You need to limit both upload and download speeds in your torrent app to approx 2/3 of capacity as there is an hidden overhead in Bittorrent which needs to be accounted for. If it maxes out the download or upload then the tracking information can't flow and it has to pause and start again.

wireless traffic has its own overhead so will be easier to max out. try limiting the speeds ttill you get stable transfer, then slowly increase till you hit the limit.

I thought of t but whatever I limit the speeds to, i.e as low as 25kbps down and 5 up it still dies :confused:

I have attached two screengrabs one of a torrent just finishing (thats why it drops, not a connection drop) and you can see when i plugged the cabe in during it, and the 2nd is a torrent downloaded 100% off ethernet with no interruptions.

I have no issues with downloading from http or ftp and can max my speed out, thats why i guessed a router security issue.

To answer your question Mark, what I expect from the torrent is the 2nd upload below, is that unreasonable :confused:

Not particularly although plenty depends on the seeds out there.

What make is your router as you may well be correct on the thing trying to stop what it thinks is a DoS attack on the router.

Not one I'm familiar with, but it's probably worth going into the GUI and having a look for security and other options which may be cutting things on the wireless only.

I'm wondering if the wireless card is doing something itself to try and be clever so it might be worth trying to update the drivers.

Also did the problem occur about the same time you installed a new Antivirus too as some of these have networking plugins.

You using UPnP? Your wireless connection will have a different IP to the wired, how is your router opening the required ports? What torrent app are you using?

Dont forget that when downloading from HTTP and FTP 99% of the traffic is one way, eg. coming to you. Torrents by there very nature are two way, this in itself could be enough to kill your wireless connection. Although your wireless connection maybe rated at 54mbps, you will very rarely if ever get that speed. Distance from the router, obstructions and other wireless networks and devices operating on simillar frequencies will all dictate your max speed. WPA/WPA2/WEP also add an overhead as each packet has to be encrypted and decrypted at both ends.
