It’s really not a good idea to use tools like that without spending some time understanding what you’re doing. They will lead you to all sorts of wrong conclusions, like being under a DOS attack. Your first step would be to spend some time studying TCP and how it works. When you know that, you’ll be able to interpret what the tools are telling you.
Cable connections are digital. That means they either work at full speed or don’t work at all: they don’t slow down like a kinked garden hose.
Changing the DHCP range is very tangenital to the purpose. Set the range to include only as many DHCP connections as you think you might reasonably need in the future. Then set your computer’s IP address to a fixed value outside of that range, but still within the router’s routable range. Ex:
DHCP Start: 192.168.2.2
DHCP End: 192.168.2.4 OR DHCP Range: 3
Set your computer IP to: 192.168.2.7 Use this fixed IP address to forward your BC listen port on your router. Set the rule to allow both TCP and UDP, or “ANY”. If you must choose one or the other, make two rules, one for each, same IP.
You are not under a DOS attack, and if you were, that wouldn’t have helped. The internet at large cannot detect your computer. They detect only the router, nothing behind it. Such an attack would have to be directed at the router, so changing subnet IP’s would not affect that at all.
From your previous study of TCP, you understand that packets must be ACK’d, which takes upstream bandwidth, in addition to whatever Bitcomet is uploading. It’s very easy to choke the upstream pipe with more data than it can handle, since it’s a lot smaller than the downstream pipe. If you allow this to happen, bittorrent actually starts interfering with itself – let alone any other poor app trying to use the connection. So limit your upstream bandwidth to 80% of capacity, as directed in the settings guide, and you should be able to netsurf while downloading.
I’ve got the same problem – as soon as I start BitComet 0.70, my internet connection for other programs like browsers slows down dramatically. I also experienced that sometimes everything works fine, but some minutes later everythings slows down again. Throtteling down BitComet to some kB for uploads does not help. Could there be a problem with DNS requests?
If you are having a DNS problem, it would manifest with BitComet and your browser frequently reporting “site not found” or “host unreachable”. It would give you an error, not a slowdown.
I’m new, and I’m having just the same problem as the OP. When i’m d/l torrents using BitComet, I cant surf the WWW at all. My browser (be it IE, Opera, or Firefox) just cant open ANY site.
I got the problem solved by calling my ISP and asked them to clear the connection (I’m on cable btw).
But right now, I am SCARED to death of even opening BitComet. Coz as soon as I open BitComet, all the pages in my browser just stop loading
I found this board seeking an answer to this very problem. For me it was sharing too many files.
When I share a lot of files I can no longer use my browser. So I only share one file at a time. And I can surf with no problem. Sometimes my mouse even goes haywire if I share too many files at once. Just a suggestion.
For me, this problem has bugged me for a long long while.
I figured that it is my router that’s choking because of the amount of connections open.
So just yesterday I’ve bought a Linksys WRT54GL router and add it to my network.
So my crappy cheap modem no longer has to be the router and modem by itself.
This helps. I am having constant 160KB/s transfer rate for hours now (I am having 1.5mbps DSL). I’ve no more problem surfing while Bitcomet is running.
Ok so I’m having a similar problem, but not the same. When BitComet is running IE AND FF both randomly stop working for about 10-15 seconds. It gives me the “this page cannot be displayed” error, and magically it will stop. I know it’s BitComet doing this because as soon as I close it I stop having the problem. I’ve already had pg2 for a while now, and i dont usually upload more than 4 kb/s anyways (just my luck, it’s set higher). Any suggestions, because I didn’t read anything that seemed to work for the past posts…
Actually, whenever BitComet download drop to 0%, all surfing, ftp…thing that require internet connection will seems to jam. Once it is even running at 1kbps, everythings back to normal.
I solved that by buying a new rounter. I am now running at constant 150-160kbps if the torrent has good seeds and many peers.
