Torrents Constantly Disconnect Internet

Asked by Evan Kollath on 2012-01-02

I'm running 10.04 LTS. I've used multiple BitTorrents and whenever I turn them on, my entire home wireless network disconnects and reconnects. I have tried to limit the number of connections and have messed with other bittorrent settings, but it doesn't help. Torrents work fine on Windows 7. Any ideas what is going on?

Thanks in advance for any help!

If it is taking down your entire network (i.e. more than one host on your network), it sounds like a problem with your router, and its processing is being disrupted by bittorrent packets. Have you tried

* Disabling Upnp, and instead forwarding ports manually. Upnp support can be flaky on some routers
* Updating your router firmware
* Limiting bandwidth on bittorent (this is pretty obvious)
* Altering the security settings on your bittorent client (partial/full/no encrption)

Whilst you are doing this, I'd make sure you have only one or two outgoing connections at any time.

I'll give those all a try. I'd like to note that I have severely limited the bandwidth on my bittorrent with no change. I'm also going to try on a different network to see if that makes a difference.

Forcing encryption seems to have taken care of the problem. I'll mess with the settings a bit more just to confirm.

To assist other users who may be searching for a solution to the same problem, can you post your ISP and/or router details?

Evan Kollath (ekollath) said : #5

All though it seems to have helped the problem. Forcing encryption wasn't enough. I just want to point out that I never had a problem like this while running Utorrent on Windows 7. I'll post my router details as soon as I can.

What do I need to do to get the information that you need?

mycae (mycae) said : #7

Just post the name of the company you pay for internet, and walk over to your router, and somewhere on the back, or underside there should be some kind of model number.

Just so we can clarify, this *is* affecting multiple computers -- not just the one running the torrent program, right?

Evan Kollath (ekollath) said : #8

My ISP is Charter.

I have a Netgear Wireless Modem, model number CGD24G.

It seems to disconnect no matter what I do, but I don't think it has anything to do with the number of connections. It disconnects faster when it is downloading faster as far as I can tell.

I don't know if this has any significance, but the port for incoming connections is marked as "closed."

And yes, this does disconnect my entire network for just a few seconds, and then it reconnects.

Finally, I have a computer running Utorrent on Windows 7 that has no problems at all downloading multiple torrents and high speeds.

If you need any more information, please ask!

I've got an update. Any sort of download, not just torrents, causes my internet to disconnect. Eventually, I can't even see my wireless network. I tried to update to 11.10 but had some issues and am trying to work on those at the moment.

It does sound suspiciously like its a fault with your router handling packets from your ubuntu client -- there should be no way any host can remotely cause your router to reset without requiring administrative rights.

Try altering the encryption type on your network, and see if that changes anything? Also, if the ubuntu host is close enough, try switching to a wired connection.

Unfortunately, I was not able to locate any firmware upgrades for your device.

Evan Kollath (ekollath) said : #11

Wired connections work fine. I have an Atheros AR5001 wireless card which (from what I can tell) may have some trouble working with Ubuntu. I don't know for sure, but it can't hurt to provide more information. I'll also try changing the encryption type on my network.

Evan Kollath (ekollath) said : #12

I'd just like to point out that this doesn't occur only on my home network. I also can't stay connected to public WiFi networks although it doesn't shutdown the whole network. In these cases, only I am disconnected.

Can you help with this problem?
