Bittorrent disables internet connetion

[bert07]

Several times now, whenever I want to download using bittorrent, my Internet connection becomes disabled.

I tried several Bittorrent programs now. And everytime, after a while,the connection (not only the bittorrent but the complete wireless connection) fails and can not be restored before reboot, loosing everything I had downloaded at the time.

Using Ibex.

 Broadcom AirForce One 54g
 Broadcom bcm4318e chipset

Wired:

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

I'm okay with that. I might have been too hasty at that point. It also depends on what one means by "security".
I felt that when ones Internet (wireless in this case) disappears, something was not so secure.

Anyway. Feel free to contact me for more info. But I doubt I can give you more.

Oh yes, at the moment I'm using Ibex x86_64, but it first happened with Ibex desktop i386.

I suspect this to be more of a bug with the kernel drivers for your Broadcom wireless card than with the the bittorrent client. It's not unusual for flaky drivers to give out due to BitTorrent, which is a high-stress workload -- rarely do other services on a desktop regularly go out and open 150 simultaneous TCP connections!

[bert07 (marien.bert)]

Possible. But I never experienced this before on previous distro's with another Bittorrent client.

Mind you: I only have that computer for about seven months and I do not often use Bittorrent for downloads (not on Linux anyway); just... I often tried to use it the last 4 weeks, and I never got a complete download.

If you think it is something else than the Bittorrent clients, maybe you can inform the right people for this?
