teh.godfatha Posted August 5, 2007 Report Share Posted August 5, 2007 Quite recently I've been having problems downloading continuously without connection interruption. After starting up Utorrent and downloading, my connection will be perfect for a random amount of time (can be 2-3 hours or 20-30 minutes, different every time), but then everything stops. Utorrent dl and ul speeds flatline at 0, and I cannot surf the web. This also causes the internet to stop working for the rest of the wireless network in my house ( my parents & sister, who dont download anything, they just browse the web.) To fix the network, I have to unplug both the router and modem. This problem first occured when I was using BitLord a few weeks ago, and it happened out of the blue. (i have been using torrents for well over a year with no problems.) Then I got smart and started using Utorrent, which seemed to fix the problem, but it happened again. I have no idea what is causing this to happen. Heres what I've done and my network specs:router: D-Link DI-524modem: whatever my ISP, RoadRunner, gave usPC: IBM something or otherwireless desktop card: D-Link DWL-G510Utorrent settings: (im using Utorrent v1.6.1)I use port 46622, and its fowarded correctly,Global max connections: 150max # of connected peers: 90# of ul slots per torrent: 4I have disabled DHT and UPnP (due to advice given on other threads on forums from other people's problems), upload speed limited to 40kB/sANY help will be greatly appreciated. Thanks. Link to comment Share on other sites More sharing options...
Ultima Posted August 5, 2007 Report Share Posted August 5, 2007 How fast is your connection? What do you have net.max_halfopen set to, and if you've ever patched TCPIP.sys, what is/was the limit set to?D-Links are known to be problematic with too many connections, so you might want to lower the global maximum number of connections to something like 60 (?) to see if the problem persists.

teh.godfatha Posted August 5, 2007 Author Report Share Posted August 5, 2007 my net.max_halfopen is set to 8, and ive never patched TCPIP.sys (im not sure how to). when i did the speed test, my connection speed was around 4000k and i think roadrunner is rated at 6,500k, so im a little worse than everyone else using it. my wireless connection is 54 Mbps, though Link to comment Share on other sites More sharing options...
Ultima Posted August 5, 2007 Report Share Posted August 5, 2007 Er, I meant to ask how fast your upload speed was (should've been more clear about that). Link to comment Share on other sites More sharing options...
teh.godfatha Posted August 5, 2007 Author Report Share Posted August 5, 2007 the speed test showed around 300k or something, but i cap it at around 40, because that seemed to give me the best download speed (which runs somewhere between 60 and 200Kbps on most torrents) Link to comment Share on other sites More sharing options...
Switeck Posted August 6, 2007 Report Share Posted August 6, 2007 An upload bandwidth of 300 kilobits/sec max cannot upload at 40 KiloBYTES/sec. Even its theoretical max is only 37.5 KilBYTES/sec...with probably more like 30-33 KiloBYTES/sec usable after figuring in TCP/IP + BitTorrent protocol overheads. This overload might partially explain your network shut down.Your wireless connection is fast enough that it shouldn't be an additional bottleneck speed-wise to µTorrent's ability to access the internet at full speed...but it may limit the max number of ip-to-ip connections you can have going at once. Wireless is just "weak" that way. Link to comment Share on other sites More sharing options...
Ultima Posted August 6, 2007 Report Share Posted August 6, 2007 And have you limited the global maximum number of connections to around 60 like I suggested? Link to comment Share on other sites More sharing options...
teh.godfatha Posted August 6, 2007 Author Report Share Posted August 6, 2007 yeah its working now, so hopefully it wont stop. ill let you know in the morning how it goes (its 12:15 am eastern time here). limiting the global connections has seemed to cause my download speeds to climb up real slowly, maybe even limiting them.Thank you for all the help. i really do appreciate it.**ok so that seemed to work last night. i'll see if it can go for more than 4 hours today... and was there anything i needed to change with the net.max_halfopen setting?***dang, it stopped working again.

Switeck Posted August 7, 2007 Report Share Posted August 7, 2007 Have you tried just resetting your computer OR router OR modem but not the others to see if the network comes back to life again?If turning the router off then on again 'fixes' things, chances are you've got a dud router.Ditto for modem.If it's your computer, it could just be a software driver problem or (going) bad network card.

teh.godfatha Posted August 10, 2007 Author Report Share Posted August 10, 2007 i think its probably the modem, but im not sure why because it was fine for a very long time Link to comment Share on other sites More sharing options...
Switeck Posted August 10, 2007 Report Share Posted August 10, 2007 With more conservative settings, µTorrent may not cause your modem to overload and crash so quickly. Link to comment Share on other sites More sharing options...
