n00dled00d Posted May 13, 2008 Report Share Posted May 13, 2008 I've been using uTorrent for years and never had any problems until yesterday.Around 4 pm on tuesday, my internet connection died. I tried using "repair" on the connection but it didn't work. All it got me was a private IP-address because it couldn't get one off the DHCP. After that I attempted an ipconfig /flushdns, ipconfig /release and ipconfig /renew. Same result.I had to reboot in order to get internet working again, for a few minutes. Then it happened again and I was forced to reboot. So far rebooting is the ONLY way I've found to get an IP-address again.It took me half a day to find that bittorrents are the culprit. When uTorrent isn't seeding or downloading anything, everything works just fine. As soon as I attempt to start a torrent or download a new one, I lost internet connection. The connection icon down in the systray goes totally black.Downloading files (tried both small and large, from multiple servers, simultaneously, to both my harddrives) using Opera and IE works fine. So does FTP, surfing the web, talking through skype, using Live Messenger, filesharing (extensively) using eMule, playing games and everything else I've thrown at it. I tried using BitComet and Azureus, and I lose internet connection as well.The only thing I tried that works is if I start a virtual machine running Win 2k with uTorrent in VmWare.My configuration is as follows:* MSI P35 Neo2-Fir Motherboard* Core 2 Duo E6750 CPU (overclocked to 3,4 GHz)* 4 Gb of Crucial BallistiX DDR2-ram* MSI Nvidia 7600GS gfx-card* Seagate 7200.11 320 GB as system drive* Western Digital Caviar GP 1 TB as a storage drive* Running Windows 2003 Enterprise Server with SP2 on an educational licenseMy ISP is Bredbandsbolaget 100 mbit and I have no router nor firewall of any kind, only a gigabit-switch and I get the same problem when I try connecting the ethernet-cable directly to the computer.Other things I've tried in different sorts of combinations without any luck:* Updating BIOS, Intel motherboard drivers and Realtek 8111C (NIC) drivers* Turning off TCP offloading in the NIC-driver* Turning off overclocking of my CPU* Changing ALL SORT of settings in both Azureus and uTorrent including encryption on/off, port used, number of connections etc* Running Windows in safe mode with networking* Shutting off the Windows firewall* After the connection stopped working, restarting the Windows DHCP Service* Running no other program but uTorrent* Shutting all the hardware down for 10 min before starting it up again* Making sure all cables are connected properly* Checked for Spyware using HiJackThis, Ad-aware, Spybot, Combofix, GMER and Windows Defender* Checked for viruses using the retail version of NOD32* Made sure I have all the latest Windows updates as of today* Waiting, just waiting for the internet connection to come back up after I quit uTorrent[Edit: Added:* Turn off NOD32 and the Windows Firewall* Tried different torrents from different trackers* Changing the number of half-open ports using the patch from lvllord.de* Ran LSPfix (it found nothing wrong)* Reset the winsock using netsh* Tried the official Bittorrent-client, Bittornado, uTorrent 1.6 and the 1.8 beta* Ran Realtek-diagnostics, no errors* After the net goes down, reset the NIC-driver using the Realtek-diagnostics tool* Ran Registry Repair* Checked the Windows System and Software log, no errors in it* Tried a really old Realtek driver for the NICWhat remains to try that I can think of:* Run Diskcheck on both harddrives (will take many hours)* Try using a dedicated NIC (I don't own one though and would need to buy one)I haven't changed any settings, installed or uninstalled any programs or done anything prior to this happening.Both uTorrent and Azureus work just fine if I run it in a virtual machine or on my laptop (running Win XP SP3). If I start a few torrents that I'm seeding, and there are no leechers everything works fine. As soon as someone starts downloading, hence making me seed, I lose my connection.Since I've run out of ideas, I'm all open to suggestions.Thanks./nd Link to comment Share on other sites More sharing options...
