On this laptop, with Ubuntu 10.10 beta (though 10.04 was the same) the wireless will occasionally crash/disconnect under moderate transfer loads. Then it will not reconnect without a reboot, although sometimes leaving the wireless switch off for 5-10 minutes before turning it back on will allow Ubuntu to reconnect. Note that this laptop does not have the same problem with Sabayon Linux running the 2.6.35 kernel.

One more note, in case it makes a difference: Sabayon working fine is running KDE, and Ubuntu 10.04 or 10.10 having the problem is running GNOME.

carltonh, thank you for reporting this bug and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
