Bug Description
Every so often I lose connectivity. This is very similar to bug #984552. Tricky to reproduce because it doesn't seem to affect me quite as frequently as the reporter of #984552. I will post ping output showing packet loss the next time I experience the bug.

Leif Halldor Asgeirsson, thank you for reporting this and helping make Ubuntu better. Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http:// cdimage. ubuntu. com/daily/ current/ . If the issue remains, please 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/KernelMainl ineBuilds . 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.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Please let us know your results. Thanks in advance.
