Bit Torrent making Websites Timeout

steviec

This problem has started happening in the last two weeks or so. Basically, when I run Bit Torrent(azureus client), websites start timing out. It doesn't happen immediately, usually I have torrents running for 15-30 minutes before websites stop working. The thing is it only effects websites - MSN Messenger and PuTTY remain unaffected, and bit torrent itself runs fine too. The second computer on my network also fails to load webpages, and the xbox can't connect to xbox Live either, so it's not limited to this computer. If I close Azureus everything runs again immediately. Then I can load Azureus back up and websites will continue working for about 15 minutes or so till it kicks in again.

I'm on Esat BT with a Zyxel Prestige 623R-T1 modem feeding into a U.S. Robotics 802.11g Wireless Router (USR5462) which my computers are wired to. This started happening about 2 weeks ago and to the best of my knowledge I never changed anything with my set up to provoke it.

Any ideas?

The problem is Zyxel Prestige 623R-T1 modem. It has great difficulty handling simultaneous connections to a large number of discrete IP's.

Lower your maximum upload settings in Azureus and see if that helps.

DemonOfTheFall

Cap your upload in azureus to something a bit lower than your max upload.

EG. if you have 256k upload, cap it to 22k or so
if you have 300k upload, cap it to 28

etc.

steviec

I'd already thought of that and dropped it to 15k with no luck. Thought I'd go further today and dropped it to 5k though and so far so good.

DemonOfTheFall

I'd defo blame the ZyXel then. I had that same one before.

I had to turn it off then on again after using torrents, or else it would be adding ~50ms to my pings. Nothing quite as severe as you're getting, but it realyl wasn't a happy camper with torrents.

I replaced it with a spare eircom wireless one that a friend had. Torrents worked much better, pings were lower, connection dropped much less.

steviec

Hmm interesting. Even at 5k up it still seemed to be causing problems. I might look into a different modem then, would anyone have a recommendation considering I already have a wireless router so i just need something simple and reliable.

Well i use azureus and i cant browse web while downloading,happned when i was with esat bt and also now with magnet.Lowered upload it dosent help.
Azureus is java baised so,i think it win98 and java,cos im on win 98,only thing i can put it down to.

zuma

If your running Win98 then your computer must be very dated and the memory hogging of Azureus may be a significant problem.

Try out Bitcomet as it required far less resources than Azureus!

As per others:

Limit your upload
Pause when surfing - run when asleep (definitely broadband only)
Download torrent client with smaller footprint (azreus is crazy) - I recommend bittornado

http://www.bittornado.com/download.html

Hagar

Are you sure your probem isn't with peer guardian or similar software?
It's surprising some of the routing involved in reaching ordinary web-sites.

cregser

If (as someone suggested) the problem lies with the Zyxel's inability to handle many simultaneous connections, limiting the bandwidth is not addressing the issue.

Limit the amount of connections instead. In my Azerus setting, the max connections is set to 50 per torrent and 200 overall. Try reducing that number. Take note of the number of peers connected when you start noticing the problems.

Blindpew

I have the same router but use Bit Tornado for torrents and don't normally get any problems with web sites loading. However anytime my daughter uses MSN I find I can't open any websites when she logs off. I find if I wait about half an hour that I can access the web again, however if I reboot I can get back on straight away. I don't know what causes this but I'm suspect of MSN as it only occurs when the Mesenger is used.

Geff

Cap your upload speed to something like 1k or 2k.

Anything over 5k is going to kill your browsing speed for web browsers.

I have the same problem.

Download uTorrent as well.

fatherdougalmag

As a matter of interest, is this down to router h/w or upload contention? I have the same behaviour on NTL. If I leave upload unreigned, download goes to ****e. But if I cap it, download performs better. I guess it's down to upstream ACK's on the download. I'm using a Belkin router.

slave1

I'm using BitComet on a BT 3Mg connection with standard Z router and have my uploads capped to 20k, no problems whatsoever with browsing, generally taking 100k to 300k depending on the file/seed/peer etc

chamlis

Don't be to hasty changing your modem. I seem to have the same problem with Azureus, as some people here. No browsing but everything else is fine.
