Title: bitTorrent kills the router?
Post by: CadErik on May 10, 2008, 09:01:56 PM
It seems that everytime I start a bitTorrent client on one computer on my network, maybe 10 minutes after, all is down: no more wireless (association still shows on but no connection), internet is deadly slow... Any chances the QOS engine is down when there are too many connections?

If your BT is cloging your pipe then the router is going to preform badly. In my home I had to set BT to be 255 for the QoS.

Here look at this.

Thanks alot, I configured the priority on the incoming connection and it seems to help but I haven't figured out how to control the port for the incoming connections, I don't want to set all ports at low priority on this computer... Any suggestions for controlling the outcoming connections?

Erik.

Hi,

the DIR-655 is my first router, so i'm not really a pro in this topic.
I'm a software engineer, and one of our project uses bittorrent technology to distribute patches/updates/etc amongst clients (cca. 200 maybe). I started to work at home and i bought the DIR-655 because of its "award-winning QoS (Quality of Service) engine" and the ability to handle gigabit traffic (which is working flawlessly). However, when i start up the application, that utilizes the torrent technology, after a couple of minutes the router disconnects from the internet. At first i thougth that our program does something wrong, so i installed uTorrent 1.7.7 and tried to download an ubunto distro (and an episode of my favorite TV show, but you didn't hear it from me :) ) but it gave me the same result... The router doesn't reboot, just drops the connection and reconnects after a couple of seconds. The wierd thing is: if i disable the qos engine in the router's config, everything works fine. Well, not everything... the torrents are working, my connection is stable, but my browsing slows down dramatically, which is normal, i think, with disabled qos.
I've browsed through all the related topics, and did everything... played around with settings, tried almost every firmware i could get my hands on, restored factory settings... but still no luck.
Is this normal? Should i return the router and ask for an another one?

Some parameters:
ISP: T-Online (Hungary, PPoE)
Modem: D-Link DSL-360R (find nothing about this hardware on the internet... strange)
WAN port set to 100Mbs
FW: 1.11_MSBeta
HW: A2

Thank's in advance for any help you can give me.

Hi,

i've tried that too. I gave a low priority to bittorrent (255) with these settings:


Then i tried without any rules. No luck. The only solution for now is to disable the qos engine... which is not an option.

Check your router log after you see the problem.
Are you getting "deauthentications"?
If so, try updating your wireless network interface drivers.

Are you running this machine wirelessly? If so does this behavior continue hardwired?

Sorry, forgot to give you any detail about this.
The wireless radio is turned off (don't have any wireless device), my connection is hardwired through cat5e cables.

I have no trouble with port forwarding. Incoming connections are working fine for about 1 or 2 minutes, then the router disconnects from internet.

I have owned a DIR-655 for almost seven months and have had the same experience as RadyR from the beginning.  The router is reasonably stable when traffic is low (transferring small files to my NAS or light surfing on the Internet).  However the router connects and reconnects periodically when I use a bitTorrent client (I use Azureus) or if I am streaming a video to my D-Link DSM-520.

I have also tried many firmware versions and experimented with turning off the radio, turning off QoS, manually forwarding ports, turning off UPnP, and turning off WISH.  All with no improvement.

Strange? I never bother to set anything in the QOS and the BT connections have max out at from 2.95MB/s 3.10 MB/s for downloads.

Correct, but their claiming to have connection issues with other computers wht BT is running. Also what client are you using?

Oh really! I no problem with other 8x client boxes and 7x network A/V media streaming boxes  running with BT is running.. Azureus 3.0.5.2

Results at 2.95MB/s using  Azureus 3.0.5.2 and DIR-655 A3/1.11

For those here who are reading this post, to get the best speed from BT and your network without LAG on the other network nodes (devices) for those of you who are not net savvy as yet.

This is how I setup my DIR-655 A3/1.11 with external unmanaged 8-port switch with 96KB packet buffer for each node (device) connected
(http://img2.putfile.com/thumb/5/15102233698.jpg) (http://www.putfile.com/pic/8227542)

There are 2x 8-port switches additional throughout the place. BT, network streamers and wireless all going off at the same time with no problems.

Most people don't have a 96kb packet buffer in their network hardware. The solution I was giving was for the router, obviously if you have a hardware flow control device, you're going to be ok.

Well true, but DLINK should encourage users to get external switch to attach to this router or any of the routers they sell. I find this problem with most routers on the market. What's DLINK 8-port switch packet buffer Green model? Users could use that or the Gig switch version.

Post by: Lycan on June 03, 2008, 03:37:00 PM
The idea is a one device solution. Most people are not going to spring for a second device unless they absolutly have to.

The point is that Tipstir's tip is handy, if you have flow control on your switch. Otherwise, follow the FAQ.

It appears that RadyR and myself are having the same problem.  We have both tried adjusting the QoS (as recommended in the FAQ that has been suggested), however the router continues to drop connections (with and without wireless on).

What is the make and model of your modem? Also who is your ISP?
Title: Re: bitTorrent kills the router?
Post by: mikeh on June 03, 2008, 05:46:23 PM
My modem is a Speedstream 6520 and my ISP is Aliant, a division of Bell Canada.  The 6520 is setup as a bridge and the DIR-655 receives a dynamic IP through a PPPoE connection.

What I have pictured is what I had with DSL and Speedstream 63xx modem.  Prior dlink router and dlink 5-port switch.

Below is how I had finally setup to get around the DSL woes..
(http://www.techspot.com/gallery/data/501/dsl.jpg)

NID - network inferface device or modular phone connection box (one line filter goes into this box) download speed will increase by 100%
NID is different you need to tap into the main line as show above using a phone junction box these are cheap and use it with a pair of cat 5e cables which you cut off the ends. Connect to the screws on both ends and then run a line which would be for the modem Cat 5e Ultra phone cord to the modem.

need one of these to the modem

I have dsl-360r modem and adsl 3mbit/sec.
I have a very limit download speed connection, which results in message that port is closed.
How should I set port in dsl-360r in order to receive bes connection speed?

I also had recurring disconnects when i ran my uTorrent client. Make sure that you set the total global connections to a reasonable level. I had to set my global connection limit to 200 which was plenty for what i need anyways. just a thought. Play around with your connection settings in the bitorrent client. I also only have one file downloading at a time. haven't had a problem since i made these changes.
