both down and up speed downs to 0

The problem is: the download and upload speed drops to zero, then it raises sudenly, then they drop again and so on. Http works fine and other applications. Overload is not the problem since it also happens when i'm only seeding.

Try this.

Disable TCP Auto-Tuning in win 7 (or Vista) ,koz it can koz problems, and now after restart it looks ok.

Its uploading at max all day. I hope its ok now. (i disabled Netbios over tcpip too)

Check the state or current setting of TCP Auto-Tuning

1. Open elevated command prompt with administrator's privileges.

2. Type the following command and press Enter:

netsh interface tcp show global

The system will display the following text on screen, where you can check on the Auto-Tuning setting:

Did you try to disable firewall. What happens?

[GB]

I disabled tcp auto tuning and netbios simultaneously or one at a time and it still didnt worked. I am using no firewall, no av. The os is win7 build 7600 (final).

LE:

bt.transp_disposition

Specific combinations:

5 - TCP incoming + outgoing only (uTP disabled)

10 - uTP only

13 - TCP incoming + outgoing with uTP outgoing only (*1.8.3 default)

15 - both TCP and uTP, incoming + outgoing (*1.9 default)

Works fine with value 5.
