large samba transfers kill wireless

Bug #292895 reported by jarome on 2008-11-03
Affects Status Importance Assigned to Milestone
linux (Ubuntu)

Bug Description

Binary package hint: samba

In 8.10 (32-bit) on an HP 2133 Mini-Note with a Broadcom BCM4312 wireless card, if I try to copy files from a windows share to my laptop, after about 30 MB, the wireless connection dies. Always. I am using the hardware Broadcom Driver that was suggested to me after the install.

What is worse, it it impossible to dismount the remote disk, and it is also impossible to cancel the file transfer in the file transfer dialog. Breaking a network connection is a commonplace event. I should be able to clean up after it without a reboot!

This seems like an issue with the wireless driver to me.

The wireless driver might be at fault, but the fact that I cannot dismount the drive or end the file transfer after the transfer dies is probably attributable to samba, or some OS issue.

That seems to be a different issue, please open a new report for that, reassigning the kill wireless to linux. thanks in advance.

I am not sure what "that" refers to. And I am still left with poorly functioning wireless. Even without samba transfers, it dies, and then it says there is no wireless until I reboot.

Can you confirm this issue exists with the most recent Jaunty Jackalope 9.04 release? Or If you could also test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine this issue. Refer to

This seems to work in 9.04 so far. A 146 MB transfer worked. Thanks.
