Wired Network Stops Working

[Kevin]

Hi, this is the second bug I report, and I hope I'm reporting that one in a better way than the first, I'm including a report at least this time xD

The thing is that sometimes wired network stops working and needs to be turned off and on to get it back to the work. It's happening weeks ago, is not a recent problem, that's why I decided to finally learn how to generate reports and submit the bug ^^

Sorry, but I cant check if it happens as well using wifi... I've got no wifi card on this PC :(

Thanks and sorry my bad English ^^

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.
