Downloading Torrents Causes WiFi Crash (must restart)

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information.
Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:

1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vnvn > lspci-vnvn.log" and attach the resulting file "lspci-vnvn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

 We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments.

By the way, i also cannot reboot the system. I've been always using
command sudo
reboot, and it doesn't work after crash. Downloading perfectly with the wire
connection. So, if you will find any solution, please let me know. Thank
You.

I also must force restart/shutdown. Everything is fine hardwired for
me as well. I have found no solution so far but will definitely share
with you if I do as I know how frustrating it can be.

If I attempt to reconnect to the network it will just act like it's trying for a long period of time, sometimes ask me for the WEP key (which is already entered), and will never actually reconnect, after maybe five minutes (literally), it will finally state "Disconnected" and stop trying.

Hi. I have exactly the same problem. Ubuntu with latest updates. (X or L ubuntu).

uname - a:
Linux 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux

I am attaching the required dmesg and lspci files.

After starting a torrent download, in serveral minutes the system crashes.
I created a script which logs system acticity in every minute. The script is not logging anymore after this.
So clearly not only the torrent client, or the wifi, the complete system is crasching :(

Without torrenting everything is fine.

Actually, I found something what can help:

from the dmesg on the failing computer (it's an old comp, I'm using it kind-of as a server):
[ 0.216109] IP route cache hash table entries: 2048 (order: 1, 8192 bytes)
[ 0.216992] TCP established hash table entries: 8192 (order: 4, 65536 bytes)
[ 0.217207] TCP bind hash table entries: 8192 (order: 4, 65536 bytes)
[ 0.217411] TCP: Hash tables configured (established 8192 bind 8192)
[ 0.217422] TCP reno registered
[ 0.217435] UDP hash table entries: 128 (order: 0, 4096 bytes)
[ 0.217475] UDP-Lite hash table entries: 128 (order: 0, 4096 bytes)

dmesg on my desktop computer:
[ 0.219149] IP route cache hash table entries: 131072 (order: 8, 1048576 bytes)
[ 0.220665] TCP established hash table entries: 524288 (order: 11, 8388608 bytes)
[ 0.224791] TCP bind hash table entries: 65536 (order: 8, 1048576 bytes)
[ 0.225311] TCP: Hash tables configured (established 524288 bind 65536)
[ 0.225314] TCP reno registered

[ 0.225372] UDP-Lite hash table entries: 2048 (order: 4, 65536 bytes)

Clearly, the values on the better computer are way higher than on the other.
Can somebody tell me where I can increase these ?
