Bit Torrent killing web access

Hi all,
I'm having some problems with my DSL. Whenever I'm downloading from Bit Torrent (using BitComet v0.58), my web access goes. I cannot even get access to Google. Whenever I try, I'll get timed out or cannot get a connection. I'll have to go and close BitComet in order to regain web access. I did not set my upload too high, only at 30k/s and my line is albe to get up to 695k/s (according to the speed test on dslreports) and the download speed with BitComet is around 100k/s and higher, but my Web access is down even if I'm downloading at low speed, like around 30k/s. I wonder if I'm setting something wrong or does anyone using Verizon DSL experience the same problem? With my old line I don't get such problems...

I'm with Verizon (in the West LA area) and just upgrade to their 3M/768k DSL from 1.5M/128k. using the Westell 2100 modem flashed to the latest firmware Also I've got a new Linksys WRT54G router with latest firmware. I've two computers hooked to the Linksys. Both computer experience the same problem. If just one computer is downloading BT, no computer can get web access.

Any suggestions? Thanks a lot
 
wild guess, but windows xp sp2 has a maximum number of simultaneous internet connections. Your bittorent program might be reaching this number and thus, your internet browser cannot gain access.
 
I've heard similar issues with various BitTorrent clients. Might I suggest www.bittornado.com I've used it a lot without any issues.

FYI, the '695k/s' that you see on that speed test was probably in kilobits per second, not kilobytes. Divide 695 by 8 to convert it to KB/sec, which is probably what you set your upstream for in your Torrent client. (in terms of KB)

kbps = kilobits per second (kb/s)
kBps = kilobytes per second (KB/s)
 
Jtoxic: I've changed the registry to allow more than 50 connections at a time (I've up it to 300), so that shouldn't be a problem.
jamesbond007: I've been using Bit Comet for quite some time already and haven't have an issue with it until now. I've also tried using previous versions that I've never had problem with, but no luck. I'm aware of the bit and byte conversion, and my upload is set to 10-30k bytes/s total for both computers, so that's well below the max upload speed I can get. I usually only get my upload to at most 50% of my max upload speed, that way my download won't get choked (since my line is ADSL).

anyone out there experiencing the same problem?

thanks
 
Try lowering your upload to 10k or less. I use to have it at unlimited and uploading at only 14-18k and it totally kills my web access. I have it at 5k and I sometimes still get pretty good download speeds with that.
 
It was actually the router, according to a post at DSLREPORTS forum, the Linksys WRT54G's firewall keeps logs on unclosed TCP connections for 5 days. This logs get so huge from downloading BT and clogs up the router's CPU and RAM, hence stopping new connections to open. The only way to fix this is to flash the firmware with one of those 3rd parth firmware (in my case, I use HyperWRT) and use one of the Startup Script posted which limits that log to a more manageable size.

now I'm downloading BT at 300+kbytes/s... SWEET 😀
 
I'm having this same problem and I hate it! I don't really understand what the 3rd party firmware does for the router. I'm using a netgear RT314 router.

This is not true. Sp2 has a limit on the number of UNCOMPLETED connectons. Not simultaneous internet connections. Kindly stop repeating this lie.

Do you have any further info on this startup script? I can't find out how to manage the log size anywhere on HyperWRT's website.

having same issue here and I'm using this same router. what BT client are you using? this seemed to start happening once i switched to bitcomet, but i guess im downloading more than i was before.
 
Here's the forum post:
Posthttp://www.dslreports.com/forum/remark,12956291~start=62

Here's the script
echo 4096 > /proc/sys/net/ipv4/ip_conntrack_max
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
echo 512 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts

You've to get the HyperWRT firmware, or other firmware that let you use startup script

I'm using BitComet 0.58

good luck
 
To the OP.

If you max your upload bandwidth, then your internet connection will get extremely bad. Try using Azureus to manage your torrents. It has a lot of customizable features and you can specify the max upload bandwidth for it to use. That's what I do, and it works really well for me.

Do you think simply copying and pasting that script will work? I have HyperWRT installed and I c & p the script but I haven't noticed much of a difference with torrent speeds yet.
