Long Time uTorrent User - Brand New Problem


Recommended Posts

So, I've been using uTorrent for quite a while, never had this problem.

I'm using a DSL (3/mbit down) connection from a Paradyne 6218-I2 modem/wireless router. It supports UPnP (turned off).

I have a desktop PC running a fresh install of Vista Ultimate x64.

Windows Firewall is off, no AV/firewalls installed.

I have setup a static IP ( for the PC, and forwarded a port (45408).

uTorrent gives me a green icon, says everything is cool.

The problem is that both on the PC and on my laptop (connected via wireless) browsing slows to crawl when uTorrent is enabled (I've tried setting the U/L speed to 5/kbs, still the same), and on top of that I get terrible D/L speeds.

I've tried tons of things (enabling UPnP), various different configurations of uTorrent, even installing XP within a virtual PC, and running uTorrent via there, all with no luck.

# Restart µTorrent, your computer, modem, and/or router after performing any of the suggestions below - Done

# Try lowering net.max_halfopen to 8 or lower - Tried 1 and above, currently set to 8 again (I saw no difference)

# Try disabling IP resolving in the Peers tab's context menu - Off

# Try disabling DHT (Can be found in Preferences > BitTorrent) - Off

# Try disabling UPnP and NAT-PMP (Can be found in Preferences > Connection) - Off

# Try disabling peer.resolve_country if it isn't already set to false (Can be found in Preferences > Advanced) - Set to false

# Try lowering maximum global number of connections to 200? 100? 50? Lower? (Can be found in Preferences > BitTorrent) - Tried everything between 20 and 200 still no dice (currently 100)

# Try patching TCPIP.sys (Windows XP w/ SP2, Windows 2003 w/ SP1, or newer)? Windows Vista users can try this out, but no guarantees are made. Users not on Windows XP w/ SP2, Windows 2003 w/ SP1, Windows Vista, or newer can skip this step. - Tried and it blew up my Vista install

# Connect your computer directly to the modem to make sure the problem is not caused by the router - Already done.

Port Checker reads good, closest speed test reads 3608 KB down, 326 KB up.

You can't connect multiple computers directly to a modem. If you turn off the router functionality it should revert to "access point" mode. Also called pass-through or "bridge" mode. This means that going from the ISP -> modem -> your computer is 1 link, instead of the modem -> router -> computers as a link to allow multiple machines on your end.

Are you using Ctrl-G Speed Guide settings < xx/384Kbit ? If you're trying to pump out too much data it's very likely that's the problem. Other causes of LAN-wide problems aren't as obvious since you already turned off DHT. Is your modem configurable as far as connection timeouts?

You'll probably be better off using the 320 kilobits/second upload settings in the 2nd link of my signature.

If your ISP is screwing with BitTorrent traffic, OR those ips you connect to are often on hostile ISPs...then set OUTGOING encryption to either Enabled or FORCED.
