IF YOU HAVE SPEED ISSUES READ HERE FIRST

[h]COMMON PROCEDURES THAT SHOULD BE FOLLOWED, REGARDLESS OF THE PROBLEM[/h]

• Make 100% sure you read the setup guide properly and in its entirety
  
• Set your firewall up properly, if applicable (find some settings guides here)
  
• Select the correct upload speed in the Setup Guide (included in setup guide, but just to be sure)
  
• If you already have a rule/exception created for µTorrent in your firewall, try removing and recreating it
  
• Read the entire FAQ
  
• Search the forums for similar problems, using keywords and such
  
• Use the newest version of µTorrent (latest beta if there's a public beta testing build available)

[h]SLOW/INTERRUPTED INTERNET CONNECTION OR OFFLINE TRACKERS[/h]

While µTorrent is running

• COMMON PROCEDURES (THIS IS A LINK -- CLICK IT)
  
• Restart µTorrent, your computer, modem, and/or router after performing any of the suggestions below
  
• Try using Switeck's conservative settings
  
• Try lowering net.max_halfopen to 4 or lower (Can be found in Preferences > Advanced)
  
• Try lowering bt.connect_speed to 4 or lower (Can be found in Preferences > Advanced)
  
• Try disabling IP resolving in the Peers tab's context menu
  
• Try disabling DHT (Can be found in Preferences > BitTorrent)
  
• Try disabling UPnP and NAT-PMP (Can be found in Preferences > Connection)
  
• Try disabling peer.resolve_country if it isn't already set to false (Can be found in Preferences > Advanced)
  
• Try lowering maximum global number of connections to 200? 100? 50? Lower? (Can be found in Preferences > Bandwidth)
  
• Try disabling uTP? (Set Preferences > Advanced > bt.transp_disposition to 5)
  
• Try patching TCPIP.sys? Only users running Windows XP w/ SP2 or SP3, Windows 2003 w/ SP1 or SP2 need to pay attention to this step. Users running Windows Vista or newer with the latest service packs are not affected by half-open connection limits because Microsoft has removed the limit from newer OSes, and as such, a patch is not necessary for those OSes. It is important to note that this step should be a last-resort step.
  
• Connect your computer directly to the modem to make sure the problem is not caused by the router

[h]SLOW TRANSFER SPEEDS[/h]

In µTorrent (be it upload or download)

• COMMON PROCEDURES (THIS IS A LINK -- CLICK IT)
  
• Restart µTorrent, your computer, modem, and/or router after performing any of the suggestions below
  
• Make sure you have a green network status light in the µTorrent status bar and/or the port checker in the Speed Guide (Ctrl+G) shows the port to be open
  
• Try testing a torrent from OpenOffice.org, Slackware Linux, or Ubuntu Linux? (If any of them run quickly, then the problems you're experiencing likely lie only with the swarm)
  
• Try enabling Protocol Encryption? (Can be found in Preferences > BitTorrent)
  
• Try disabling bt.tcp_rate_control? (Can be found in Preferences > Advanced)
  
• Try various uTP settings? (Set Preferences > Advanced > bt.transp_disposition to 31 to enable, 26 to force, 21 to disable)
  
• Make sure peer.lazy_bitfield is enabled? (Can be found in Preferences > Advanced)
  
• Test your connection with Glasnost to make sure your ISP isn't throttling BitTorrent (and check this thread for a compiled list of ISPs known to throttle)

[h]THINGS TO TAKE NOTE OF[/h]

• If you find your speeds to be "average" until you get to a certain percentage, check the availability of the torrent, and the number of seeds/peers there should be in the swarm. If the availability is below 1.0, [ if the number of seeds is high, the torrent is likely fake | if the number of seeds is low, then you're going to have to be patient ]. If you're getting a large number of hashfails, the torrent is likely poisoned, or your hardware can be at fault (this isn't limited only to routers -- the problem could stem from bad RAM or hard drive or hard drive cables, for example).
  
• If you have NO control over the router configuration, you will be unable to forward your ports, and speeds may suffer (this applies especially to students using a university-supplied connection)
  
• The µTorrent settings files can sometimes get corrupted. As such, try deleting settings.dat and settings.dat.old from the µTorrent settings directory and reconfiguring from the beginning (with the above suggestions in mind)

[h]SOME SPECIFICS...[/h]

• Look here to see if settings for your firewall are listed here (if you're not sure how to configure your firewall)
  
• AMD Athlon 64 X2 users: If you are having slowed connections, check this thread out
  
• BT HomeHub users: If you can't forward your ports, check this thread out
  
• Linksys WRT54G/GS/GL users: If you don't know what version of the router you're using, check here
  
• Microsoft Windows 95/98 users: You should have your global maximum number of connections set lower than the value for the MaxConnections value in the Windows TCP/IP Registry Entries.
  
• Motorola SurfBoard modem users: You may be unable to forward their ports properly (check here if the link is down)
  
• ESET / NOD32 users: NOD32 is known to cause slowdowns with the internet connection while µTorrent is being run. If you are using NOD32 v2.7.x, check here. If you are using NOD32 v3.x, check here.
  
• Wireless/satellite Internet connection users: Chances are, you will be permanently firewalled, and will not be able to forward your ports. This is not to be confused with regular wireless LAN connections.

[h]INFORMATION WE MIGHT NEED IF NOTHING ELSE HELPS[/h]

• EVERYTHING you've tried so far, including ANYTHING listed above (please be as explicit and specific as you can). Tell us what your changed settings are.
  
• The state/value of all of the options you were recommended to change up above.
  
• Color of the network status light in µTorrent's status bar (at the bottom of the µTorrent main window)
  
• What the port checker from the Speed Guide writes
  
• What the Speed Guide shows your settings to be (press Ctrl+G in µTorrent)
  
• What you have net.max_halfopen set to (Preferences > Advanced in µTorrent), and if you ever modified TCPIP.sys, what you patched the limit to
  
• Operating system installed (Windows XP, 2000, ME, 98, 95, NT? Something else?)
  
• Security software installed (firewall, antivirus, antispyware, antiadware)
  
• Exact router model(s), and exact modem model
  
• ISP (Internet Service Provider) being used
  
• Connection type (DSL, cable, dial-up), and the results obtained from the speed test (when running the Speed Guide), for both download AND upload. Be sure that you aren't using your connection for any other reason besides testing, while testing. That means no downloading, no IMing, no µTorrent running, no browser activity (other than the testing), etc. Additionally, no other computer on your network (if any) should be using the connection. When you select a testing mirror, use the ones that are geographically closest to you.
  

BE PREPARED TO PROVIDE THE FOLLOWING PIECES OF INFORMATION UPON REQUEST:

• Basic computer hardware specifications (motherboard and/or chipset, CPU, RAM, drive type, etc.)
  
• Your list of running processes (get both):
  a) get HijackThis from www.trendmicro.com, run it, view the log, and post the contents here
  get Process Explorer from www.sysinternals.com, run it, Ctrl+D (to show the lower DLL pane), select the µTorrent process from the list, Ctrl+S (and save the list somewhere you'll find easily -- like the Desktop), then post the contents of the saved process list in the .txt file here
