Rasmus4J Posted December 15, 2010 Report Share Posted December 15, 2010 Hi all,Sorry if this is a double/triple/whatever post, but I have a serious problem (or, the rest of the household has)...We have a 15/15 mb/s fiber connection in the household (mostly when measured at www.speedtest.net, it is more like 30/60 mb.. now, the problem is that recently when I use BitTorrent 7.2, and I dl, no matter the speed, almost our entire connection is taken... but as soon as I pause BT, the connection is back up... what can cause this? I have changed no preferences, and it has just suddenly started to act that way...best wishesRasmus Link to comment Share on other sites More sharing options...
Switeck Posted December 16, 2010 Report Share Posted December 16, 2010 My guess is you NOW have enough busy torrents to finally overload your networking somewhere.Number of simultaneous connections can matter more than speed for a connection that fast, and many consumer networking products (be they routers, modems, NICs, or even software firewalls) can overload even before they reach 100 active connections at once.1st link in my signature.Also try rafi's uTorrent Guide: http://forum.utorrent.com/viewtopic.php?id=74820 Link to comment Share on other sites More sharing options...
Rasmus4J Posted December 16, 2010 Author Report Share Posted December 16, 2010 Hi Switeck,I tried following Rafi's guide (part 2 & 3 I think it was), and looked at the 1st link in your signature,but neither helped...The problem more specific, is that it is not only on my pc the connection drops almost completely, but EVERYTHING. I'm on cable, so that's not why, but also our laptops, which run on wireless, drop...and as far as I remember, it's only the download which is affected Link to comment Share on other sites More sharing options...
Switeck Posted December 16, 2010 Report Share Posted December 16, 2010 Wireless connectivity is often far worse in both reliability and speed over wired Ethernet.Wireless-G often cannot even sustain 20 mbit/sec down and up on a LAN with just ONE computer to a wireless router and adding more just reduces that further.The 1st link in my signature should give strict enough reduction of settings in uTorrent to at least get back up-and-running for everything ELSE on your network while uTorrent is active. From there, you can add back features and raise settings slowly to determine which triggers disasters.In my experience, DHT, uTP, Local Peer Discovery, UPnP, and NAT-PMP are the most likely to cause problems. This is not counting bt.connect_speed being set higher than 2 outgoing connections attempts per second or net.max_halfopen set higher than 8 half open outgoing TCP connection attempts at once.

Rasmus4J Posted December 16, 2010 Author Report Share Posted December 16, 2010 well, it has never been a problem before, as mentioned. Even though we use 2 laptops, and 1 desktop (2 at max), almost every day...The effects are the same for the wireless as well as cable connection, and it occurs as soon as i hit, download. I've already tried port forwarding, and I have a Bittorrent exception in my bullguard firewall (no settings changed there either).. I've tried lowering both net.max_halfopen to 8 and bt.connect_speed to 5 (as Rafi's guide suggested), didn't help... Link to comment Share on other sites More sharing options...
Switeck Posted December 16, 2010 Report Share Posted December 16, 2010 The few times I've seen Bullguard firewall mentioned on these forums, it's ended in disaster:http://forum.utorrent.com/viewtopic.php?id=74044http://forum.utorrent.com/viewtopic.php?id=73448http://forum.utorrent.com/viewtopic.php?id=71668With uTorrent's connection pressure, Bullguard could even be spitting out malformed packets for what little I know. At the least, other posts suggest it is not stable. Link to comment Share on other sites More sharing options...
Rasmus4J Posted December 16, 2010 Author Report Share Posted December 16, 2010 I must say, that I have never heard any of those problems, and can't complain about bullguard I didn't notice the age of the posts you linked to, but I don't think (not sure, but my theory is) that bullguard has anything to do with it Link to comment Share on other sites More sharing options...
Switeck Posted December 16, 2010 Report Share Posted December 16, 2010 Disable almost everything in uTorrent at once, limit it to fewer than 50 total connections.I want to know if you can set it so low that it doesn't cause problems.THEN, we can see what's causing problems by re-enabling things...

Rasmus4J Posted December 16, 2010 Author Report Share Posted December 16, 2010 ATM. I'm not downloading, and don't have anything I need to DL, so there's no problem, but by disable everything you mean ? sorry, but there's A LOT of functions When I have something ti DL, and I'm then able to test, I'll post it here, ASAP!

Switeck Posted December 18, 2010 Report Share Posted December 18, 2010 "but by disable everything you mean ?"...What was listed in 1st link in my signature and Rafi's link. Link to comment Share on other sites More sharing options...
