TCP issues: Connection goes to a halt when uTorrent is used

[The Pentium Guy]

This has been puzzling me for a while...

I can browse the internet at fast speeds, fine.

But I start a torrent download, and whether it starts uploading at 1kbps or 200kbps, my internet (as in port 80, firefox/opera) just don't work. The pages just refuse to load... staying at 0%. I pause the torrent, and 20-30 seconds later my internet starts working again at the same fast speeds.

As soon as I start it again it slows down like crazy...

What should I do to fix this?

Did you configure the port setting on gateway?
Also check the settings on torrent!

Could you explain?

You need to open TCP 6881-6999 for Torrent on your gateway under firewall rule or virtual server if your version is older than 3.2.

There is no version 3.2 in uTorrent (that's what the OP is using). Also, the port is randomly set when you start the application the first time. Opening 6881-6999 won't do a thing unless that's what he's using (by the way, you don't need to open up all those ports. Just one is enough).

Port's already been forwarded... I think it has to do something with the TCP settings. The guy ran DrTCP on my thing and maybe entered the wrong settings? I'm not sure.

First of all, what kind of internet connection are you on? What are your upload/download speeds to be precise.

Once you figure that out, you need to configure your torrent client so it doesn't saturate your connection/speed.

Fair enough!

But what is that single port? just randomly choose?

My guess is the router is choking cause of all the active connections.

[About Actiontec router freezing]

They also searched the broadband reports forums and verified that this situation is generic to the actiontec router when connecting to steam game server and possibly Bittorrent.

Damnit. Why am I the only one complaining about this problem then? Does everyone else use a different router?

You are not the only one having this problem.

I have to reboot the modem every hour when I have a BitTorrent running.

If you have a solution, other than buying a different modem--such as the Cisco 678--I would certainly like to know.

Did you try another computer to see if you get the same problem?

You said that as soon as BT starts up everything else goes? Try limiting maximum simultaneous connections in your client and seeing if you can get it to work with a low number.
