Please help me with this problem

I am running a WinXP sp2 home installation. I dont have any kind of LAN in my PC. I have applied the patch to increase the tcpip connections. This particular problem started yesterday.

I am a cable internet user. Yesterday when I was using Azureus to download a torrent (@ 100+ KB/s speed), the download suddenly stopped. When I checked the connection, I found that none of the internet applications are working (including browsers, chat pgms). Basically net was killed somehow. I restarted the modem and it started working again. But again when I start Azureus, it downloads for about 1 to 2 mins and kills the connection. I believe this happens once the seeder+leecher no. becomes very high.

I tried changing the bittorrent client, but no use. I checked the eventlog. There was one error from 'IPNATHLP' (event: 32003). I havent installed NAT or windows firewall. And I disabled the Windows service which starts them.

Still the problem continues but now the 'IPNATHLP' error doesnt come. If I try any other protocol for downloading, this doesnt happen. But with bittorrent, it occurs.

I dont know what to do. I hope the Internet Gurus here can help me in this matter.

welcome to neowin.

you see, p2p is only half-legal so i hate giving you support for it. so..you know p2p includes uploading aswell..not only downloading..that might kill your line. i know aol doesn't like up- and downloading at the same time.

Do you use a router or something similar? I've had a similar problem before where the amount of connections that azureus is doing is filling up the connections table on my router, consequently when I try to use any other internet-using program it fails.

My solution - change the maximum amount of connections used for azureus (found in configuration). I have it set to 300 and seems to be fine for me atm.

Hope this helps

I know p2p is half legal, but I dont think this problem will be restricted to p2p alone. I think it happens because many people try to connect to my PC simultaneously. That can happen in other ways too.

I hope someone will be able to find a solution.

No I dont have any router. I shall try your tip about Azureus and get you back. But the problem persisted even when I changed the client. Therefore there must be a generic solution.

I've been having problems with p2p also. Even though I'm only downloading at ~80kb/s it completely kills the LAN speed. We can't load up a webpage without problems on any machine on the LAN and there's 4 computers.

Are u using Internet Connection Sharing?

No man. It is not working.



No, I am not using ICS.

Search a patch whose name is EvID4226Patch.exe from google. It might be helpful!

don't worry, your problem happens with a lot of people as I have found out over the past. I think it has a lot to do with your cable modem and how it works. I have the same problem with or without a router. I know it is very annoying because you cannot download anything consistently over bit torrent without having to constantly monitor your connection. Anyway, good luck finding a solution. BTW, is it a Linksys modem? That is the one I have seen do it the most. The motorola surfboards seem pretty good from what I hear. Maybe try one of those. If you find an answer, be sure and let me know.

I think the patch you are talking about is the one which modifies tcpip.sys to increase the no.of connections. If so, well, I already applied it.



I am using a Motorola surfboard SB4200 modem.

What firmware does your SB4200 have. If it's any version earlier then 4.4.2 it needs to be updated or else your crashing problem will continue when using any app that requires a sudden large amount of incoming/outgoing connections to be made.

The firmware is SB4200-0.4.3.3-SCM01-NOSH.
But I have been using this MODEM for quiet some time and this problem started only yesterday.

I had that problem with Zone Alarm 5 that killed my connection till I switched back to 4.5
