Bug Description

The problem is that after several minutes of been connected by wireless it suddenly just disconnects appearing the meesage:

<Now you are offline>

By restarting the adapter, the computer or the network settings (several times) the connection is reestablished, sometimes.

I have tried different drivers and updates for this card but the problem persists since I installed Ubuntu 5 months ago. Further information about the computer and the connection

Hello and thanks for the reply,

I updated the Bios as was mentioned and this is the output of the command:

sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
F.66
01/24/2013

But the problem with the wireless connection remains.

Alejandro, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-3.XY-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-3.XY-rcZ

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

I tested several of the upstream kernels, but none of them solved the problem. Just recently I updated all the packages and between them one update to the kernel 3.13.0-48-generic, I think it solved the problem. Yesterday I was connected for more than 4 hour and today for almost 6 hours without problems.

I have tracked the problem about the unstability, I'm not sure what all the lines mean but what I can see is that the network supplier changes continuously and Ubuntu was unable to follow these changes in some point.

Hello Christhopher, I started testing the kernel 4.0.0-040000rc4 and the previous versions, the -rc5 was not available by that moment.
