uTorrent overloads my router

[FelikZ]

Hello! I use DSL-500T router to connect the internet.

When uTorrent is working more than an hour or two, start huge packet loss.

The problem is solved off uTorrent or reboot your modem and running uTorrent again for an hour - two.

I phoned tech support and they told me that the losses arise because of too many connections - as I understood because uTorrent.

Additional info:

- Tcp.sys patched up to maximum 100 open connections.

- Net.max_half_open is set to 16

Help please:]

ps. google translator used

[DreadWingKnight]

An increased net.max_halfopen is INCREASING the speed at which your router is dying.

Turn it down to 4.

[FelikZ]

Ok thx, I will try to set 4 and post result here.

-> 8+ hours with normal connect = perfect!

-> download speed near to maximum = perfect!

-> upload speed.... near to nothing. This is a coincidence or because of half_open connections?

[Switeck]

Upload speed is probably nil because no peers are trying to download from you.

[FelikZ]

Damn... I think the problem is not max_half_open ... Today felt cover those issues that always, but with max_half_open = 4 ... As before, when you close uTorrent, the connection comes back to normal.

In what could be the problem?

Try lowering your max connection count and disabling DHT.

[FelikZ]

I even "finished" all the torrents (all the torrents were not active) and turned off DHT - nothing has changed. : (

Can recommend some software to catch the problem?

You using uTorrent through a VM?

Teredo active as well? (It's very hard on routers if uTorrent is aggressively using it!)

[FelikZ]

>You using uTorrent through a VM?

No. VM just installed on my PC.

>Teredo active as well?

Yes, active.

[Switeck]

Try disabling Teredo/IPv6 then I guess.

[FelikZ]

Switeck, I disabled it - nothing changed

Ok. The real issue in "Maximum open connections" option. I set it from 50 to 30 and (for test only) set net.max_half_open to 16 -> now I get a perfect connection for 11 hours!!!!.

Thanks a lot!!
