Repeated disconnects?

Wofi · February 4, 2009

The image below mostly speaks for itself. When using uTorrent for downloading, I experience frequent disconnects that force me to restart my router each time it happens to regain a connection.

But there appears to be no discernible pattern as to why it happens, I can be downloading at ~150kb/s (the max for my connection) or even at ~10kb/s, they can happen several times an hour or maybe once a day.

(apologies for the large image size)

I'd appreciate any help you could offer,

Thanks.

EDIT: Out of sheer stupidity I forgot to list my connection and whatnot:

OS: Windows XP

ISP: Optusnet ADSL (Australian)

Connection speed: 1500/256

Router: D-Link DIR-300

Mode: D-Link DSL-302G

And Avast antivirus.

I can put in settings for uTorrent that would virtually guarantee that happens.

But you didn't mention what settings you're using, so I can't rule out that you've done the same.

Wofi · February 5, 2009

I had tested almost all of Ultima's Guide (testing the TCPIP.sys patch now) and I went through and followed your guide a couple of days ago, so the settings I'm using at the moment are:

Bandwidth

Upload rate: 10kb/s

Download rate: Unlimited

Max connections: 60

Connected peers per torrent: 35

Upload slots per torrent: 3

BitTorrent

All except "Limit local peer bandwidth" ticked

Encryption enabled

Queueing

Max active torrents: 2

Max active downloads: 1

Advanced

Default but the ones suggested in Ultima's guide,

net.max_halfopen 8

peer.resolve_country false

Pretty much every different setting I've tried so far hasn't really had any influence on the problem.

(While typing the post (~10 minutes) it happened twice more.)

If there's anything else you need let me know,

Maybe other software on your computer is interfering.

Do a process explorer list of uTorrent's DLL processes.

Wofi · February 7, 2009

I think this is what you're looking for:

Thanks for helping me by the way, I appreciate it.

I need it as raw text. A picture is harder to see and harder to quote from.

This:

NMIndexStoreSvr.exe 2012 Nero Home Nero AG

I don't know if it's a problem for you, but indexing services usually lock uTorrent out of its own files.

Wofi · February 8, 2009

Interesting, I don't think I've ever had that sort of problem, but anyway I tried killing the process and started up uTorrent again, but it disconnected in less than five minutes.

Switeck · February 9, 2009

I just don't understand enough about Process Explorer and HijackThis! lists to spot what's causing your problems.

Needless to say, if it isn't hostile software on your computer...or bad networking hardware...then it may be your ISP.

Have you done internet searches about your ISP disrupting BitTorrent?

Wofi · February 9, 2009

Wow, I hadn't thought about doing that...

Damn, listed as a "Bad ISP" on the AzureusWiki. Apparently it "limits bandwidth for accounts with a high traffic volume". Which I find interesting, because it doesn't seem to block HTTP or any other sort of traffic. Maybe it just blocks unknown/typically unused ports.

Anyway, thanks for all your help and I suppose I should go find another ISP.

Switeck · February 10, 2009

It's not hard with connection monitoring software to spot almost certain BitTorrent traffic...even without knowing what torrent/s are running or what trackers are being connected to.

BitTorrent has a BIG obvious sign with 1 incoming listening port with lots of peers/seeds connecting to it. And if any of them aren't using encryption, then ALL of them on the incoming listening port can be assumed to be BitTorrent traffic.

Outgoing is a tiny bit harder to determine if it's encrypted...but there's still patterns, such as retrying the same "dead" ips over and over again...or packet sizes...or call-and-reply behavior between the uploader and downloader on that connection (they can be both if both are peers).

Some ISPs just throttle everything they don't recognize...and throttle recognized BitTorrent traffic even further.

Not many ISPs that I know of still use break-the-connection techniques to hinder BitTorrent traffic.

ComCast (mostly!) quit.

This can be badly out-of-date:

http://azureuswiki.com/index.php/Bad_ISPs

...with a handful of ISPs getting better, and numerous more getting a LOT worse.

Methods change, new screw-the-customer hardware gets added or updated.

To really find out about your ISP's methods, try DSL reports forums:

http://www.dslreports.com/forums/all

...and try to get in touch with local computer people who also (are forced to) use the same ISP as you. I've tried local computer stores myself with some success...asking both customers and employees. It depends on how much competition there is as well as luck finding someone else who better understands the problems.

Changing ISPs can be a dangerous undertaking...the OLD ISP can be vindictive, such as continuing to charge after cancellation (the AOL approach) or not allowing you to get a new MAC code for your dry DSL line to the local exchange (ADSL ISPs in the UK approach). The NEW ISP can be as bad or worse than the old...as they're all in collusion over how much to charge and what minimal quality of service to provide -- sometimes forced by the government!

Wofi · February 10, 2009

Unfortunately, most of the people around my areas usually either don't use my ISP, or aren't tech-minded enough to get much information from. Pretty much all of the telephone lines are owned by one company, owned by the government and everyone pays a rental fee.

But the ISP I'm looking to change to is based in my state only, running completely on their own lines instead of the major company's. It's currently cheaper, faster and comes recommended by a few friends of mine, so that's probably where I'm headed before the new month rolls over.

I am having the same problem as Wolfi,

If I go to the security event viewer in computer management after the disconnect occurs, I get a bunch of errors with the type:"Failure Audit". When I open the error, it says:

Do you get the same error Wolfi? Does anyone have any insight into this?
