Title: Bittorrent speed
Post by: lamonsas on December 31, 2009, 10:21:26 AM
hey guys, got my dlink 655 a4 a few days ago, its been great, but only one thing i cant figure out, when i try to download a torrent, any torrent from any site, i tried a few of them.  the speed of the download is very unstable, the speed goes up to around 1.5mb/s then drops to 8kb/s in a matter of 2 seconds, then it goes up again to 500kb/s and it plays around like that, my defective router was not doing this, what could be causing this?

which torrent client you're using? I've seen this behavior with utorrent 2.0 RC2 and I do not have it with the old version 1.8.5.
Title: Re: Bittorrent speed
Post by: MitchSchaft on December 31, 2009, 10:50:45 AM
Have you tried forwarding the port utorrent uses to that PC? That may make a difference.
Title: Re: Bittorrent speed
Post by: EddieZ on December 31, 2009, 10:59:52 AM
Torrent speed depends on the speed of seeders. And that can vary, you will never be connected to a high speed seeder continuously.

Post by: lamonsas on December 31, 2009, 11:32:28 AM
there is no need to foward any ports because UPNP is enabled , and i checked in the program's settings and it says PORT OPEN so yea upnp is great it opens the ports automatically, im using a mac,   i tried using uTORRENT and TRANSMISSION,  like i said i replaced the dlink 634m with this router and that 634m was not doing this.

my speed used to be a constant 1.5mbp/s

Lower your upload speed.
Title: Re: Bittorrent speed
Post by: lamonsas on December 31, 2009, 05:44:34 PM
in the program i have the UPLOAD speed limited to 5KB/s
Title: Re: Bittorrent speed
Post by: Cobra on December 31, 2009, 08:48:51 PM
Does that include when seeding?

You have to set that too or the client will try to go unlimited which will kill the connection.
Title: Re: Bittorrent speed
Post by: lamonsas on December 31, 2009, 09:09:31 PM
yes when seeding.
Title: Re: Bittorrent speed
Post by: lamonsas on December 31, 2009, 09:38:01 PM
Ok i just tried downloading with uTorrent , my speed came up to around 850kb/s and it stayed at that speed and didnt go down like it was happening when i used Transmission to download the torrent, but why does it stay at that speed and doesnt go up more? i ran a speed test on speedtest.net and i have 15mb/s download!  i mean with the other dlink router that i replaced i always had 1.5mb/s download on almost every torrent.  is there something that may be limiting my speed in the router's settngs?
Title: Re: Bittorrent speed
Post by: Cobra on December 31, 2009, 11:24:41 PM
Is this on wired or wireless?

If wireless you may want to try a different channel.

Also, Speedtest.net is not a very reliable test if you have Comcast cable or another ISP with Powerboost.
Powerboost can make the test wacked.

More accurate ones are at dslreports (http://www.dslreports.com/speedtest).
Title: Re: Bittorrent speed
Post by: EddieZ on January 01, 2010, 08:05:02 AM
Again, BT does not have an 'advertised' speed, each torrent will be different. Some will connect to a fast seeder (uploader), some will not and connect to low speed seeders. Also, most BT clients have a mechanism that will combine your upload speed with the download you get. So there's a very slim chance the router has anything to do with it.
Title: Re: Bittorrent speed
Post by: lamonsas on January 01, 2010, 10:46:13 AM
its on a WIRED connection, and i have time warner cable WITHOUT POWERBOOST.
Title: Re: Bittorrent speed
Post by: Cobra on January 01, 2010, 11:36:38 AM
A lot of things can affect wireless.
I would start with changing the wireless channel as the DIR 655 could be using a different  channel than your other router did and could be one that your neighbors use.
Also try changing your 802.11 mode.
Title: Re: Bittorrent speed
Post by: lamonsas on January 01, 2010, 11:44:37 AM
oh man i ment to say its on a WIRED connection(my iMac) , i edited the post above.
Title: Re: Bittorrent speed
Post by: lamonsas on January 01, 2010, 05:04:10 PM
something is hurting my download speed, i ran a test on dslreports and i got 11mb/s download,   my problem tho is that when i download a file even in firefox, the speed is not what its SUPPOSED to be, i know approximatley what the speed should be  because i download from the same websites and with the old router i had higher speeds,  it must be the router, what setting in the router could be limiting my downloading speeds?

its also obvious in torrent downloading, i always used to get 1.5mb/s for download but not its no more than 850kb/s.
Title: Re: Bittorrent speed
Post by: Cobra on January 01, 2010, 05:23:34 PM
The QOS engine could affect speeds.
Advanced > QOS engine
Title: Re: Bittorrent speed
Post by: lamonsas on January 01, 2010, 05:54:15 PM
what should i change there?
Title: Re: Bittorrent speed
Post by: ozzed3 on January 01, 2010, 05:58:21 PM
Just turn it off completely by unchecking "Enable Traffic Shaping" And restart your router. I am also having issues with this router and torrents except mine freezes every 24h or so.. And I noticed that turning off QoS helps in stabilizing things a little bit.

Title: Re: Bittorrent speed
Post by: lamonsas on January 01, 2010, 06:05:44 PM
no mine doesnt freeze at all, its been rock solid, i think i figured out what the problem is , at all times, the 655 is holding some bandwidth for a possible wireless connection, im just guessing here but thats what seems logical to me. so basically ill never get a full download speed on the iMac as the 655 is saving up some bandwith for a potential wireless connection such as if i turn on the PS3 or xbox 360..   Could that be?
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 11:29:00 AM
anyone please?
Title: Re: Bittorrent speed
Post by: ozzed3 on January 02, 2010, 11:39:11 AM
No. that is not how it is. First of all, that's not how TCP/IP or any other protocol works. And I have wireless turned on, yet I get full speed when the router does work. QoS on the other hand messes with bandwidth to make sure "high priority" packets gets through. Try turning QoS off and let me know how it changes things, if it does.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 05:23:22 PM
but u dont understand , i WANT QOS to be on, thats one of the reasons i bought this router, which feature is it thats limiting my download speed like this ? QOS? which setting in QOS's menu ? there are a few there.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 05:28:58 PM
guys i have a question, in the FIREWALL Settings menu, is this what the NAT Endpoint Filtering  should be set to:

UDP Endpoint Filtering:  ADDRESS RESTRICTED

TCP Endpoint Filtering: PORT AND ADDRESS RESTRICTED

thats what its set to, are these the correct settings?
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 05:39:25 PM
also under the QOS menu i get measured uplink speed 512kb/s, is that a good result?
Title: Re: Bittorrent speed
Post by: Cobra on January 02, 2010, 05:47:09 PM
also under the QOS menu i get measured uplink speed 512kb/s, is that a good result?

It should be reflecting close to the speed you get from your ISP for upload.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 06:21:15 PM
guys, i really dont know why but now when i run a speed test on speedtest.net or dslreports i get a maximum of 2.5mb/s for download, i didnt chnage any setting i just disabled wifi protected setup, why is it not measuring my full bandwidth anymore?
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 06:55:46 PM
ok guys i tried disabling QOS completely by ticking of traffic shaping and the SPI(the firewall setting) too but i dont know for some reason my speed seems to drop to around the 200kb/s and it didnt help the problem i am having with bittorent too,  

guys but why does my speed tests show me only 2mb/s download now? it used to say 15mb/s   could it be my time warner cable modem is defective or something?
Title: Re: Bittorrent speed
Post by: ozzed3 on January 02, 2010, 08:16:04 PM
If you updated your firmware you might have gotten a bad flash.

You can try this.

Save the configuration file to your harddrive

Software reset the router

Hardware reset the router

Reflash with the same firmware you have now

Software reset the router

Hardware reset the router

Load the configuration file again.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 08:23:36 PM
no i didnt upgrade anything, my router came with firmware 1.32NA installed,  could it be that something is wrong with my cable modem? i originally replaced my DLINK 634M because i had problems with it , i never thought it might be my cable model?  is it possible?  

I could go swap the modem tommorow at the time warner center here in queens, NY.

i also noticed, i tried downloadinf iTunes from apple's website, cuz i know they have amazing download speeds, and when the download started it was 7mb/s download and then by the second it dropped and dropped until it reached the speed of 134kb/s and it stayed around that speed area. 
Title: Re: Bittorrent speed
Post by: ozzed3 on January 02, 2010, 08:31:12 PM
Do you have the possibility to connect your computer directly to the modem? If so, you can do that and then you'll know for sure if it is the router.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 09:01:44 PM
yes but heres the thing, just 2 days when i ran a speed test it was 14mb/s download but my downloads were still slow, my torrents were downloading with a maximum of 800kb/s,  which setting on the router could cause this? i tried disabling the firewall, QOS..
Title: Re: Bittorrent speed
Post by: Cobra on January 02, 2010, 09:24:16 PM
no i didnt upgrade anything, my router came with firmware 1.32NA installed

Well then you may have the DNS relay bug...this was fixed in the latest beta which I doubt your router left the factory with.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 09:31:03 PM
dns relay bug does what exactly? i have DNS Relay on, should i disable it?  what is it exactly? can you please explain, thank you.
Title: Re: Bittorrent speed
Post by: ozzed3 on January 02, 2010, 09:42:58 PM
DNS relay makes your router pretend it is a DNS-server. It is completely pointless and very stupid. You should disable it.

Just remember to restart your computer afterwards.
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 09:51:08 PM
could that be the reason why my download speed is so slow?
Title: Re: Bittorrent speed
Post by: lamonsas on January 02, 2010, 10:16:37 PM
guys, i have been googling for the past 2 hours or so and i found someone that posted a similar problem like me with slow internet DOWNLOADS, not web surfing, web surfing is super fast,  but download speeds were not good , anyway, someone posted a solution for them to DISABLE IPV6 on their machine, hence my iMac, so i did just that and went into my network prefrances and disabled IPV6, my download speeds are back now, they are not full bandwidth still but they are much much much better, 

should i disable DNS Relay anyway?  would it provide any advantage in speed?

Btw guys do u have SHORT GI enabled or disabled?
Title: Re: Bittorrent speed
Post by: ozzed3 on January 02, 2010, 11:07:33 PM
Short GI has to do with wireless and you should leave it enabled unless you are having issues with devices connected wirelessly.

DNS-relay should be disabled also. It's "yet another thing" that can cause issues if you leave it enabled. It is not needed for home networks.
Title: Re: Bittorrent speed

DNS-relay should be disabled also. It's "yet another thing" that can cause issues if you leave it enabled. It is not needed for home networks.

I agree with Ozzed: Short GI should be enabled, esp. when you use N. The shortend GI is one of the N features

On DNS relay: it does exactly what it says - relaying the DNS addresses which are sent with DHCP. This way not all clients take up bandwidth to get their own DNS query out. For small networks this feature could add some value because it can prevent browsing with the wrong settings which in its turn can add some latency ('my browsing is slow').
Title: Re: Bittorrent speed
Post by: lamonsas on January 03, 2010, 12:23:51 PM
yea but would that benefit me in anyway in regards of speed? i have a question also, in my imac's network settings there a setting called MTU , duplex and speed, mtu is set to standard 1500, duplex is set to full-duplex flow control, speed is set to 1000baseT, are these the correct settings?
Title: Re: Bittorrent speed
Post by: ozzed3 on January 03, 2010, 12:32:22 PM
Did you know that there is a help file built into the GUI?

Cut from it, it says:

"Short GI
    Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation. "

And it also has nothing to do with the wired connection, so it won't affect your speed there.
Title: Re: Bittorrent speed
Post by: lamonsas on January 03, 2010, 12:35:25 PM
no i ment to say would disabling dns relay benefit me in speed,   i have a question guys , under ADVANCED WIRELESSS what should wan port speed be set to? its set to AUTO at the moment
Title: Re: Bittorrent speed
Post by: Ronneske on January 03, 2010, 12:39:23 PM
could it be your ISP is reducing speed over regular b2b ports?

You could try to use a high port number e.g. 34632 (or anything higher).
Open this port in advance-port forwarding for the ip number of the pc in use.

Set this port number also inthe b2b client. I use uTorrent and is working ok.
Advantage of uTorrent is that it is also a small program that does not eat all our pc's resources.

You might give this a try.

Title: Re: Bittorrent speed
Post by: ozzed3 on January 03, 2010, 12:46:39 PM
Many users of the DIR-655 reports issues with the DNS-relay. You can turn it off to make sure that that isn't the issue.
Title: Re: Bittorrent speed
Post by: lamonsas on January 03, 2010, 01:06:26 PM
ok ill try that later on but i doubt thats the problem , you see, just now i tried downloading iTunes from the apple servers, as soon as the download starts the speed was 8mb/s! then it goes down and down and down to 200kb/s,  its like theres some limiter on or something, under advanced network in the router settings, what should the wan port speed be set to?

Settings are correct, don;t change them UNLESS your ISP requires a different MTU (some US ISP's do)
Title: Re: Bittorrent speed
Post by: lamonsas on January 03, 2010, 01:24:13 PM
EddieZ , was it good that i disabled the IPv6 in my imac's settings? like i said i think it improved my download speeds,  is it possible the auto lan detecting feature in the router is thinking i have a slower connection and slows down my connection?

could it be DNS Relay is causing this download speed issue? all my wireless components are working perfectly its just that my donwload speed on my iMac is kindda slow.
Title: Re: Bittorrent speed
Post by: EddieZ on January 03, 2010, 01:27:52 PM
IPv6 can be turned off without a problem, most current routers do not support IPv6 (only tunneling).

That feature can give a wrong reading. But realise that it shows a bit lower speed (explaination is in the HELP section). But if it differs substantially you might want to set it manually. Just give it a try, no problem will be caused by manual setting.
Title: Re: Bittorrent speed
Post by: lamonsas on January 03, 2010, 01:37:52 PM
well i ipv6 configuration OFF now on my imac.  i mean like i said i downlaoded itunes, the speed was 8mb/s and then the speed drops down and down to around 200kb/s , why is it doing that?
Title: Re: Bittorrent speed

guys , i just checked my logs in the router's menu and i have "1931 Log Entries"

This is just the begining of the log, the ip starting with 72 is my IP address, it looks like the router is blocking right? could this be why my downloads are slow?

Did you try the DNS Relay trick that others have suggested, or upgrade to the 1.32NAbeta09?  I had problems myself and this may or may not do the trick for you...but it's part of the process of elimination.
Title: Re: Bittorrent speed

Title: Re: Bittorrent speed
Post by: ozzed3 on January 03, 2010, 11:06:12 PM
The logs simply say that your firewall is working as it should and blocks unauthorised requests.

To disable DNS-relay just uncheck the box and restart the router if it asks you to, and you might have to restart your clients also.

And no, there are no issues with disabling it.
Title: Re: Bittorrent speed
Post by: EddieZ on January 04, 2010, 11:06:10 AM
There is no DNS relay issue anymore with this firmware. If it causes an issue, I think it is caused by your network config (router/modem/ISP). I doubt that DNS relay causes your problem. Just do a wiki on 'DNS relay' and you will know why this cannot be the cause.

Title: Re: Bittorrent speed
Post by: Cobra on January 04, 2010, 07:41:43 PM
Depends on how the swarm is but most times I start off slow then within minutes get up to and over 1 MB/s. I have had maybe two times where I was able to get up to 2 MB/s for a brief period.
Title: Re: Bittorrent speed
Post by: Krusher on January 04, 2010, 08:04:15 PM
I'll typically get 1.2MB/s once things get going after awhile.

Regarding the DNS Relay problem per EddieZ, I read elsewhere that DNS relay was fixed in 1.32NAbeta09?  It might just be a coincidence here, but no slowdown/lockup problems here since I loaded the beta.  I had the 1.32NA approved release prior to that.

The original poster's message shows that he can access the web interface however, where I could not.  But before the router went out to lunch, the symptoms were very similar for me.
