BitTorrent killing my network connection

Got my new rig built on Saturday and everything has been awesome for the most part...but for some reason I've been experiencing some network issues and would like to find out what's causing this to happen.

I've always used Azureus for my torrent needs but decided to try uTorrent since it seems to be the new favorite. I started downloading and browsing the forums as usual, but after some time I noticed my network connection was extremely slow. I'm used to it slowing down somewhat when getting decent speeds on one or multiple torrents, but it has never been THAT slow. Just about every page I tried to go to timed out, and the couple that did go through took several minutes to load. The torrent, however, continued to download at its previous speed. I checked my max up/down speeds and had them limited, so like I said this isn't the usual slowdown that you get when downloading torrents -- it rendered my network connection basically unusable. I also checked processes and nothing was hogging the CPU.

I stopped the download, rebooted, and my network connection speed was normal again. I thought it might be a uTorrent problem so I installed Azureus and started downloading the same torrent using it. Sure enough, after some time my network connection slowed to a crawl again while the torrent continued chugging along. I noticed that if I stopped or paused the downloads and waited a few minutes, the network connection would seemingly go back to normal and would work for a while after restarting the downloads, although it would eventually slow to a crawl again.

I never had this problem on my last system (DFI Ultra-D / X2 4400+) nor did I have it on the laptop in the next room which was also downloading the same torrent for test purposes.

I only had the primary local area connection hooked up to my router, and just for S&Gs I connected the other one as well. Doing this seemed to fix my first issue; it was after connecting both ports that I could download torrents and surf the web with decent speed simultaneously. I don't know why both LAN ports would have to be connected, though...maybe there is a problem with the first port? I might try it with just the 2nd port connected when I get home and see if the problem happens again.

Now, for the other issue which might have to do with my router. I left the torrent downloading on the PC, went to watch 300 (again 🙂 ) and when I came back the torrent speeds were 0kb/0kb on both my PC and the laptop. I was also unable to navigate to any websites. Had to unplug the router in order to restore the network connection and resume websurfing/downloading. This happened twice in the span of a few hours. I think it's a router issue since it halts network activity on all PCs connected to it. I'm using the Netgear RangeMax wireless G router and have had to reboot it every now and then because it'll keep a connection but simply halt all network activity. I do not have this problem with my other router (plain Netgear wireless G router); it has been on 24/7 for months without a problem.

Thoughts? I was wondering if anyone else was having similar issues with this router.

 
If BitTorrent is killing your network connection.

Get proffesional Hadware, http://www.cisco.com

Or get a separate Internet account to use with Bittorret only.

After all you probably save a fortune by getting all of the "stuff" from BitTorrent servers.
 
try this:
1. connect the PC directly to the DSL/cable modem
if it's working fine, then proceed to step 2 - if not, your ISP might be blocking certain ports - use IP spoofing or other methods

2. if it works fine without router, then it's gotta be the router's fault - your router keeps running out of memory & crashes when running BT client
here's an option: upgrade your router's firmware (get some of the enthusiast routers, if you don't already have, used Linksys WRT54G v1-v4 work best), and change the max connection settings to max (4096) and hold time (time to remember the opened connections) to min
- some routers are especially bad (w/ p2p) - they would crash every 2-3 min (e.g.: those free after rebate routers)

why you never had this problem with your old setup, I don't know

bittorent is a solid & legal p2p protocol used to download legal linux distros and other legal contents such as class lecture videos on campus network - it always tickles me when it's associated to piracy or illegal downloading
 
Thanks for the suggestions guys. I am well aware of Cisco equipment, Jack -- I'm actually a network admin. That's not to say I know everything obviously, or I wouldn't be asking questions here. 🙂 Cisco makes some nice stuff but I'm pretty sure I don't need professional-level equipment for my uses, as my Netgear WGR624 always worked fine but I'm letting my parents use it at their house right now. I thought about swapping it with my WPN824 RangeMax router but like I said, it requires a reboot every now and then even when not fooling with torrents. I want them to have a reliable, hassle-free home network and currently it's exactly that.

I'm also quite sure I don't need a separate internet account; yeah it would help, but it's not like I'm downloading torrents all of the time. Just every now and then when I need to download a good linux distro as bigpow mentioned. I've also seen some other software companies that offer their products for download via torrent so as not to consume excess server bandwidth.

Bigpow, I have cable and I'm pretty sure that Comcast does block common ports. I always configure my BT client to use a port other than the default because even if it does work with the default port settings, it's obviously a lot slower than when using an unblocked port.

I'm pretty sure it is the router, like you said. Weird that the newer one would run out of memory and hose my network connection while the older router ticks along without a problem, but as you said it could be a firmware issue. I checked for an update last night as a matter of fact and am already running the current version (I upgraded it a few months ago, so they need to get off of their arses and release a new one I suppose 😀 ).

I've heard lots of good things about the WRT54G and am aware of the firmware possibilities, so that might be an inexpensive option to try. Based on the highly knowledgeable and always accurate reviews on Newegg, the WRT54G has a lower rating than the Netgear and D-Link stuff, though. I'm not sure if that's because those people don't know WTH they're doing or if they're just not using good firmware.

I'm still at a loss as far as why I have to have both ethernet ports on my motherboard connected in order to be able to reliably surf and BT at the same time, though...when my current torrent finishes I will try it with only the second one connected and see if it duplicates the results that I had when running only the first one. Perhaps different ethernet controllers or driver versions handle the traffic differently, I dunno.
 
zero,

you shouldn't have to connect both ethernet ports to your switch/router, since only one would be active at one time (windows XP will use what it considers the best/fastest one, somehow)

*used WRT54G v1-v4 can be had for less than $30. Or get a new WRT54GL (notice the 'L') for around $60
if you have an Xbox 360, get the WRT55AG so that you could push the xbox live traffic to 5.8GHz band

I'm running a WRT54G v4 with DD-WRT firmware, I never have to reset my router after changing a few settings.
I used to run Dlink & Netgear (free after rebates POS), and I remember I had to power reset the netgear at least several times a day


check out linksysinfo.org forum for more details on which routers & firmwares to get.

as for why the review for netgear & dlink routers are better, I have no idea -
most reviewers probably consider the price point (linksys routers are definitely more expensive) and also because they run the stock firmware

I also heard good things about dlink gaming routers (cost a lot more tho)




BTW: nice 1080p LCD monitor you got there...
I know 'coz I've the LVM42W2 😀

Sure there are legal uses for bittorrent, but what % of BT usage is for legal use? 10%? I bet that's pretty damn high, closer to 1%

With the number of people playing WoW, I imagine there's a few percentage points just for that. 😛

I'll bet it's still less then 1%
