Help on torrent downloads dropping my connection

Problem short version: My connection will drop when I download using bit torrent.

Problem long version: I was able to setup the wireless connection and am able to surf the web and play online games. I am also able to view the router as a UPnP device in My Network Places. The problem is when I start my bit torrent client (Azureus, regular not vuze. It did update to version 3), it was able to download at a regular speed for about 5 mins then my connection would drop (The download speed would drop to < 1kb); I won't be able to surf the web or play online games. I am also unable to view the router using My network Places nor by manually typing the URL. It's like I don't have a connection anymore. To get my connetion back I would need to restart the PC plugged to the wireless adapter and the router, restarting only 1 of them won't work. The weird thing is that the PC connected via LAN cable to the router can download via bit torrent before and after the one connected via wireless got dropped.

My Setup: I got a linksys WRT54G router connected via LAN cable to a nearby PC and a Netgear wireless adapter (WG111v3) connected to another computer, they are seperated by a closed door and approx 5 meters away from each other.

Steps I did:

1.) I tried to reinstall the wireless adapter.
2.) I tried to reinstall the router. Rerun the setup and configuration disk.
3.) I tried reinstalling both wireless adapter and router before using the torrent client.
4.) I tried working on the NAT problem being reported by the torrent client. I tried the steps outlined in portforwarding.com. This results into:
1.) My net stops working altogether.
2.) After a few more changes, my net got back but the torrent problem is still there.
Note: There is no NAT problem in there first 5 mins or so. It will report a good connection for those first 5 mins then report a NAT error.
5.) I tried letting windows manage the wireless adapter instead of netgear's software. No change, same problem.

Notes:
1.)As long as I do not use the torrent, my connection will not drop. I can play games or surf the net for hours. Even keep the connection idle for hours and come back and I can still surf.
2.) My signal strength is usually at good (3 bars).

My friend is thinking that the problem is because I used a netgear adapter on a linksys router and I should have used linksys for both. I want to try toms first before I go out and buy myself a linksys adapter.

Can anyone help me on this.

Quick update.

I tried moving the PC connected via cable to the room and tried the netgear adapter. It worked fine this way.

I tried changing my torrent client to utorrent and the problem still persists. My router version is 7.0.0.1. Not sure if this is a local version since I only read version 5 for most.

I'll double check the number of outbound connections since it was mentioned in the torrent's router faq. If that did nto work I'll try to upgrade the firmware to 7.0.0.4 since it did mention about P2P in the release note.

If anyone has any suggestions or have this happened to them, please post and share how you fix this.

Thanks.

I was having the same problem, I downloaded utorrent and ran it simultaneously with bit torrent and reduced active torrents to one, now my connection is healthy and multitasking,

I also created a static IP and forwarded both programs to the same port, bit torrent is showing an error but is dl'ing swell.

Obviously not the problem. If that were true, the torrent would'nt work on a wired or wireless connection.

Here's another issue that I think needs addressing: If you're downloading torrents in the UK through an ISP like BT, expect your connection to drop to zero and then die. It looks like BT are blocking the associated Ports now...

I have the same exact issue; my internet surfing speed drops out and I can barely browse and other pcs can barely play online using the same home network, although connecting via cable..
I have vista on my machine, torrent client: uTorrent 1.8.5, LinkSys wifi Adapter.

However, my speed comes back again a few minutes after I quit the torrent client..

One addition, my torrent download speed is steady, I can go up to 400kbps on a 4mbps connection but only surfing becomes impossible for me on the same device and for others using the same network.

Note: connection speed drops out even if my download speed is limited to ~ 5kbps; something in the torrent client is sucking all the bandwidth..

No solution yet!

This is exactly my problem, has anyone found a solution yet??

I'm here to drop some experience on you. Cheaper/Older Wi-fi adapters can't handle multiple simultaneus connections.

FIX: I'm using Vuze but the principal is the same for other BT clients
1. open your options (ctrl+,)
2. go to Transfer (ensure advance mode is on)
3. change "max connections globally" to something like 250
4. test with a 2000 seed torrent (whatever you find, it's just a test)
5. if it drops connection again, lower step 3 by 25-50
6. keep lowering the numer until connection doesn't drop (more connections help speed)
7. enjoy

the reason enryption helps is that it connects to fewer seeds (just encrypted ones) which gives you a false sense of success, if you find lots of encrypted seeds and connect then it's back to square one, so lower max connections and ignore the encryption to get the best speeds possible with your adapter.

Hope this helps you guys!
