Utorrent Disconnecing my Internet

[adam o]

Hi guys

I am currently running utorrent on windows xp, 10mb broadband, full zone alarm and on a netgear wpn824 router.

With that out of the way here is my problem, I have done the speed tests, port forwarded my router and I get the green tick at the bottom of the program however when trying to download I am only achieving speeds around 76kbp/s which once it reaches its peak then falls down to 0kbp/s within about 15-20 seconds and sometimes I actually lose my internet connection completely for about 1minute before it reconnects automatically.

your help would be amazing

cheers

i've tried all of your list and nothing seems to be working, I have a netgear wpn824.

I managed to reach 500kb/s earlier and no when i'm downloading something with more seeds/torrents i can only reach 50kb/s is that normal?

So you're still getting disconnected from the internet? And the number of seeds is no indication of how fast a torrent will run, so yeah, the speed's probably fine if you have the green light and can get 500KiB/s on other torrent(s).

Post your settings as shown in Speed Guide (CTRL+G).

(One or all of those settings may be excessive for your connection, causing these problems.)

Also, what advanced settings changes have you done?

(Changing something there can wreck a connection if you're careless!)

[adam o]

upload limit :40kb/s

upload slots :4

connections (per torrent) :90

connections (global) :50

max active torrents :3

max active downloads :2

*I downloaded the patch that makes the net.max_half open go to 4

*i've unchecked the unable UPnP port mapping

cheers for your ongoing help

The patch is supposed to make half-open connections higher than 10, not reduce them to 4. If you input 4 as the value to use, re-run the patch and set it to 50.

In µTorrent, set half-open connection limit to only 4-8. This should eliminate too many half-open connections at once as a cause of your problems.

If you haven't already, disable DHT, disable UPnP, disable show country flags, and disable resolve ips.

These features are *VERY HARD* on numerous networking products such as firewalls (Zone Alarm!) and routers (Netgear!)

Make sure Peer Exchange is enabled though, to offset the loss of DHT and UPnP.

Your settings have only 1 odd flaw: you're allowing more connections PER torrent than you're allowing in TOTAL (global). ...possibly just a typo on your part?

Total possible upload slots = 4 per torrent times 3 max torrents at once = 12 upload slots.

So... 40 KB/sec upload speed split between 12 upload slots is still 3.33 KB/sec each -- well above the critical threshold of 1 KB/sec which can cause poor to terrible download speeds.

Are you actually REACHING and SUSTAINING 40 KB/sec upload speeds though? Your ISP may advertise such speeds as peak values but not be able to sustain such values more than short bursts of <15 seconds at a time. If it's not reaching that value, the overloads caused by it can cause internet connectivity loss.

Lastly, what's the name of your ISP?

Some of them intentionally throttle or possibly even corrupt BitTorrent traffic...either way possibly causing your internet connectivity loss.

*done the patch again and set it at 50

*the half open connections (in preferences/advanced) is set at 4

*DHT, UPnP both off

*not sure about this:

disable show country flags, and disable resolve ips.

These features are *VERY HARD* on numerous networking products such as firewalls (Zone Alarm!) and routers (Netgear!)

Make sure Peer Exchange is enabled though, to offset the loss of DHT and UPnP.

don't know what it means sorry

*oops wasn't a typo, hadn't realised they had been changed, what would be an appropriate value for these?

*yeah the speed goes up sometimes to about 60kb/s but usually stays at about 40kb/s

*I'm on 10mb with NTL

again thanks for your patience

Under advanced settings, peer.resolve_country should be set to false (the default value).

Right-clicking in the PEERS window at bottom of main screen pops up a menu...at the bottom of the menu is Resolve IPs. That should be unchecked.

Swap your global and per torrent connection limit. Make 90 the global number and 50 the per torrent number. This doesn't mean each of your 3 active torrents can have 50 connections at once, only that one could get up to 50...assuming the other 2 don't use more than 40 connections combined.
