Lose internet connection with utorrent

I've had this problem for about a month or two now and can't seem to find anything I could do. Utorrent was working perfectly fine before I had this problem. Ive always had download and upload set to unlimited and worked perfect, and now, both set to unlimited, I lose connection to the network about every 10 sec., speeds drop to 0, can't use internet, and in about 5 sec. I get my network back and utorrent starts working, and in another 10 sec. it does the same thing again.

I've disconnected my router and connected the ethernet straight to the modem and everything works fine with no speed drops ( I had to force the protocol encryption because of throttling ). I have a feeling it's some setting in utorrent thats causing the router to loose the connection, but I don't understand because I have never changed a setting and it has worked fine before.

Here is more information:

I know that the port is open because I check it often. The status light on utorrent is green. I am using windows 7 with the windows firewall and microsoft security essentials. I have road runner lite and my router is a belkin F5D7230-4 (I have seen that these are problematic but I've had this router for at least 2 years and have always worked up until a month ago). My internet speed isn't that fast, but my speed guide settings are 81 kbit/s upload speed, upload slots=2, connections per torrent=50, Max Connections=75, and max active torrents is set to 1.

I hope someone can help.

Hello.

I am sorry to say but I have no idea about that but I'll try my best level and Find solution for you till then waiting for my reply.

Thanks for sharing your problem.

Thanks for your reply. I just tried lowering the net.max_halfopen to 5 but no luck.

Take the global connections down below 60 and the per-torrent down to 40 or so.

I went to as low as putting the settings from a 56k dial-up connection, which is per torrent 20 and global 30. I think it actually helped a little. It now last a little longer to loose the connection.

Any other suggestions?

Take your belkin out back, shoot it, and get a linksys wrt54gl and put dd-wrt on it.

In general torrents will flood your PC with too many pings and corrupted packets throught your TCP/IP stack/ connection . So I found the solution to the problem was to use a software packet shaper. This is called Cfos it is very cheap at $15 i think it now and lasts for lifetime. It slows your torrents down by 30% if the packets are corrupted or going to stuff your internet browsing , However if the torrent packets are clean it will improve the speed by 30% or keep it the same. I can have full about 30 torrents going at one time while browsing is fine with Cfos running . Cfos allows a trial of 30 days here.......

http://www.cfos.de/speed/cfosspeed_e.htm detailed newbee explanation of packet shapping at thier website.

The new version 5 works with all versions of Windows incl W7 32 & 64 bit versions . Hope this helps.

The other program to consider which is free is Peerblocker . This blocks the so called bad guys who are monitoring your network / torrent traffic . They also set up systems to slow network traffic via fake torrents with bad data somehow . Using peerblocker will help to reduce bogus network trafic thus helping speed things up and also keep them from monitoring you maybe. Peerblocker seems to speed things up by as much as 20% , that is what I have noticed. The "P2P" list it blocks is a collection of media companies, who regularly scan people on file sharing networks to find out who is pirating movies and music.It does stuff which techie propeller heads could do easy but why waste time when you can get that here free and effortless. it is small takes not CPU cycles

http://review.techworld.com/security-software/3205853/peerblock-review/

Also be aware that from time to time, concider changing port number for utorrent (I use random port option )as your ISP monitors your traffic through this port and then throttles it somehow. Some ISPs do , some don't but I noticed when I changed port each week the torrents would double in speed for a while then fall back 50% after a few days.I use a FREE program called Simple Portforward found below that does it in 3 clicks.

here http://www.snapfiles.com/reviews/Simple-Port-Forwarding/simpleportfw.html

Also since routers store Network Adress Translation information ,some eventually get full or overflow so a reset is sometimes needed on some models . Though CFOS usually fixes this.

Well thats my bit . Hope this helps

Thanks for the info. I already have peerblock. Great program. I am trying out cfosspeed and the speeds are going crazy now, but no loss in connection. I guess its a trade off. I think i am gonna have to shoot it.

........I spoke too soon. I had just lost my connection.

If you know someone with a skeet shoot and shotgun then it might be far more effective and therapeutic too. PULL !!!! :-) I think all electronic equipment should come with a skeek shoot voucher so you can blast it into silicone heaven when it had it. Linksys are very good.So are D-link. I guess you tried a firmware upgrade. That usually fixes a whole swaith of issues like this.

Take your belkin out back, shoot it, and get a linksys wrt54gl and put dd-wrt on it.

Ross, I already suggested that.

I have the same problem. Before using version 2.0, everything was perfectly fine; I'm trying to re-install the older version of uTorrent to see if the problem is solved

if it works without the router then it is the router at fault . Have fun with the Keet shoot

harmonytch420 said, "my router is a belkin F5D7230-4"

Your router is listed here:

http://www.dd-wrt.com/wiki/index.php/Supported_Devices

...But it depends on exactly which build of that router it is as to whether it supports micro dd-wrt.

I've tried everything I can but it does not work:( I still don't understand why. I didn't change any setting in Utorrent. I only downloaded the newest version of it. Everytime I open Utorrent and start downloading, my internet goes down:( Then, I close Utorrent and the Internet works well again:(

Can somebody help me plz?

My upload speed now is only 30kb/s (used to be over 100kb/s) and my download is 20kb/s (was over 200kb/s last month)

1st link in my signature then, follow the troubleshooting guide for interrupted internet and slow speed.

I've tried everything I could in your 1st signature but I can't solve it:( everytime utorrent opens, my internet goes down:( It's never happened before since the last 2 weeks:(

Here is what I got from the 2 softwares:
