stop (K)torrent from using all of my bandwidth

my brother often likes to download stuff using ktorrent (a torrent program), but when he does it takes up all of our bandwidth even if its only downloading at 2kbps. Because of this, any other computer in the house becomes pretty much useless (when trying to use the internet). There has to be a way to fix this because downloading at 2kpbs should not be using up all of our internet connection.

any ideas?

o yah, and if it matters, the computer he uses to download on is connected directly to the wireless router and the other computers are connected wirelessly. It also goes the other way too, if im downloading in my room using ktorrent, the other computers become useless. Because of this, i suspect it may be something to do with router settings.

 

See if you can adjust the download rate inside the program first. Set it very low. Or disable it completely.

Have him change his settings on ktorrent to an agreed bandwidth, like 1 mbps. If that does not work cut the cable and let him run on wireless too.

But if your router supports QoS it's your best way to restrict bandwidth. Most have a setting in which the user can restrict bandwidth, priortise. Depending on your router QoS can control bandwidth. You can also block the needed ports based on scheduling. Most of these controls are found under FW rules or a QoS tab.

But the low cost routers do not support this some times. If thats the case and your router supports the dd-wrt firmware, full version you can get it.

 

ive tried changing the download rate on ktorrent, and because it doesnt matter what speed his downloads are going (they could be going at 2kbps and it still has the same connection hogging effect) i dont think thats the problem.

and i dont htink that him running on wireless would fix the problem either, because if im downloading (wirelessly) using a torrent app it hogs all the connection, then he cant do anything.

Personally i think that the QoS is the best bet, but it is really confusing and ive got no idea what to do with it. I attached a screenshot of what options i have

 

Have you read the manual? Have you visited the D-Link website and read the FAQs?

 

Pull his ethernet cable.

 

i havent visited their site, but the included help manuals seem to assume that the user knows alot about networking terms. There are just too many words they use that mean nothing to me.

 

It's not so much the actual transfers that kill it, it's the communication of small packets.

If you can, adjust your router settings.

Set your Maximum Ports as high as you can go (Mine is 4096), and I've got a TCP/UDP timeouts set at 800 seconds. If you go too low, AIM/Yahoo drop (Somewhere between 600-800 is safe for that), but if you go too high the torrent packets take up every port and fill up the slots fast.

So fire up 192.168.1.1 and see if you can find these settings to change.

If you can't, I'd highly recommend a router capable of running DD-WRT. I'm downloading a few torrents right now at 400KB/Sec (big B, as in byte) and uploading at 30KB (Big B again), and I'm doing dandy on my browser speeds.

 

Activate the QoS.
Then bring up help on the QoS and see what else you need to do. On my router I have to add a fire wall rule to use the QoS. But I have unlimited options on how to use the QoS, priortise packet, restrict band width. In your case may be on rule giving your PC Priority of the ktorrent pc. And maybe another to split the bandwidth or restrict his.

 

something is wrong for sure , i use u-torrent and even if i'm downloading at 4.5 Mbps on a 5 Mbps line my other computers never have trouble loading pages on the interweb , i even listen to streaming radio .
maybe try a different torrent client ? i know i have no special settings in any of my routers , 1 wrt 300n and 1 wrt 600n . ome torrent clients are just hogs

 

yeah, my internet isnt that good (it cant download any faster than ~250kbps)

ive put in a new QoS rule, here is what i did:
Source IP Range --> 192.168.0.146 to 192.168.0.189 [my ip for linux OS is 192.168.0.147 and my ip for XP is 192.168.0.188, so im hoping what i did here was right]
Priority --> 1 [set this to 1 so it could be high priority]
Protocol --> 6 [not sure what this does, so i left it at default]
Source Port Range --> 0 to 65535 [not sure what this does, so i left it at default]
Destination IP Range --> 0.0.0.0 to 255.255.255.255 [not sure what this does, so i left it at default]
Destination Port Range --> 0 to 65535 [not sure what this does, so i left it at default]

does this look right for my computer to have priority over the internet connection?

i havent tried this yet, as he hasnt downloaded anything since ive changed it (either that or i havent noticed). So if the problem persists ill post again

 

You never mentioned what the upload rates are, since this is the most likely thing that will affect your internet browsing. If the torrent application is using up all the upload bandwidth, then all outgoing traffic will be affected thus the acknowledgments will be hindered.

Most torrent apps should have a feature to limit the upload speed, try that and maybe reserve 10~20% of your rated upload speed for other stuff.

This won't degrade the torrent dl speed, but should let other computers use the internet.

 

Fittersman, Your setup is a little different than mine but the rule you put in should cover it. It's looked like you setup the rule to give you (range specified) prority. If you want it to provide equal to all you need to cover your complete subnet and set priority to 3.

You need to cover your bases just encase he decides to use a static IP out of your rules range.

Mine has a little more control than yours. I'm able to specificly pick, bandwidth control, que priority, std, and 2 others.

But, if the rule work you will not know if he's on ktorrent.
