      slow down when using p2p or BT -cant surf

      First off the line stats

      Connection Speed 3328 kbps 768 kbps
      Line Attenuation 60.0 db 31.5 db
      Noise Margin 6.9 db 7.0 db

      About a week or two ago I noticed my line was slow. An inspection of th router revealed a drop in connection speed to about 1200. I assume DLM. Any I rebooted and returned to normal speed.

      Th eodd thing which has been happening for some time, perhaps even before I rebooted router is that as soon as I start BT or p2p software I cannot surf. The web pages are not found. Also oddly Vuze is saying I am downloading at about 29k when my torrents are not downloading.

      As soon as I stop p2p or BT then I can surf again. Usenet is not affected.

      Is this some sinister Sky plan to stop me?

      Bittorrent and P2P can gobble up your bandwidth. If these are downloading and uploading at a rate close to your connection speed, you will not be able to do anything else. You will have to limit the bandwidth you make available to them.

      Sky do not throttle, it looks like you are throttling yourself.

      Re: slow down when using p2p or BT -cant surf

      Thanks but it must be something else. Prior to this recent period I was happily getting BT downloads of 100-200k on a popular seed and still surfing at same time. But now not. Plus the strange indication that I am downloading in the Vuez summary window and yet and not downloading the files is odd. The download speed I am getting from BT is only 20-30K and upload is restricted anyway.

      Plus, when using Usenet client I can get 300k and can surf. It is as if a switch is being thrown somewhere.

      Are you still using wireless? If so, how is it when you connect by ethernet?

      Many have found that wireless is not at all dependable, giving fair results one day then rubbish the next. A lot of the problem is its popularity, more and more ISPs are pushing 'wireless broadband' as a selling point, meaning that areas are becoming polluted with wireless waves, making a clean connection very difficult. If this is your problem, changing the router channel may help. Start at channel 13 and work down.

      Gave up on wireless a long time ago. I use ethanet over powerlines.

      Surfing and Usenet are normal speed, only when engaging BT does everything shut down and yet BT speeds are low too.

      I use CfosSpeed from here cFosSpeed, faster Internet access with Traffic Shaping after a few hours/days of training you can download and upload P2P stuff at almost full speed and the web is as snappy and fast as without it.

      That seems to suggest the problem is with Bit torrent, do you have the latest version -
      Get BitTorrent - BitTorrent

      You might want to consider uninstalling and reinstalling, you may have a corruption.

      Also, you must remember that when downloading from a server (website); such as Microsoft at 100/2000 kbps, you were able to browse fine because you are not uploading at the same time.

      Torrents and P2P gobble bandwidth by taking majority of download and upload capability. You could try and select preferences to ensure that dl/ul are controlled to your needs.

      Re: slow down when using p2p or BT -cant surf

      You need to reduce your maximum upload speed in Vuze. Right click on the upload speed value at the bottom right-hand corner of the Vuze window and select something smaller than it is now.

      Here's an explanation of what's happening. Every packet of data sent across the Internet has to be acknowledged. (Actually it's only TCP/IP packets, but let's not make this more complicated than it already is). So when your web browser fetches a web page, for every 180kbytes (or so) of data it receives, it sends a packet back to the web server, saying that it received that data OK. In other words, even when all you think you're doing is receiving data, there is still a constant trickle of data (the acknowledgement packets) going in the opposite direction, from your PC to the web server.

      Now you might ask, if that's the case (that for every packet received by my PC, it has to send out an acknowledgement), why isn't it the upload speed on my Sky Broadband connection that's the limiting factor on how fast my internet connection is? After all, the upload speed is a lot less than my download speed. The answer to that question is simply that the acknowledgement packets are a lot smaller than the data packets. So ADSL broadband works just brilliantly for downloading stuff, with big packets of data using the speedy downstream, and little acknowledgements packets using the slower upstream. The flipside of that is that ADSL broadband is pretty lousy when it comes to uploading data, and uploading is exactly what Vuze will start doing once you've completed downloading a file.

      Other people wanting to download that file from you will be using up the whole of your 90kbyte (or so) upstream capacity. And you will also see a small trickle of downstream data - those are the acknowledgement packets that your PC is sending to other people's PCs. And if you try to do web browsing while this is happening, you'll find it very slow indeed. This is not because your downstream capacity is being used up, it's because your upstream capacity is crammed full of packets of data that other torrent users want. The acknowledgement packets that your PC would normally send to a web server, get delayed and the web server starts thinking that you're not receiving the data properly, and so it starts repeating packets of data. Eventually, it may give up trying to the stream the data to you quickly, and will instead wait for an acknowledgement immediately after every packet of data it sends to you. And it's that that causes the apparent slow down in browser.

      I hope that's a clear enough explanation.

      Very good explanation James, so would setting maximum upload to say 80kbps (for Max package) be about right then?
