Comment 21 for bug 1097002

I reported similar issues as bug #1172967, so I will close that one.

The upgrade from 12.10 to 13.04 was not smooth. After restarting at the end of the process, the boot hung with a black screen. I rebooted in failsafe mode and after enabling networking I resumed in low graphics mode and was successful.

After rebooting, I had high resolution graphics but no internet connection. I rebooted again and used the 'old kernel', which is odd as it was supposedly deleted during the upgrade. My system shows that it's running 13.0.4 and I obviously have an internet connection.

I have had the same issue on three different computers with different graphic cards. When I next reboot I'll try the current kernel again.

--next day...

After rebooting into 3.8.0-19, I get an internet connection for about 30 seconds, then it drops and won't re-connect unless suspended and woke again, where I get a fresh 30 seconds before it disconnects again.

The network manager applet reports that both wired and wireless are working when they clearly aren't.

The 'phantom' kernel 3.5.0-28 in Raring is still the only one I can use to stay connected. This is the case on both this laptop and my desktop.
