cannot connect to the internet after upgrade to raring

[Christopher]

It has similarities to bug 318410. 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.

Now when I boot into 3.8.0-19, I get an internet connection for about 30 seconds, then it drops and won't re-connect unlhe ess 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.-28 is still the only one I can use to stay connected.

After further searching, this seems to be a duplicate of Bug #1097002, so I've marked this as invalid.

[Montblanc (montblanc)]

Bug #1097002 is about wireless connections, are we sure it's a duplicate? By the way, I'm experiencing the same after upgrading to raring. I'm using an ETHERNET connection, though everything seems fine system-wide (syslogs, network manager and so on). To be able to connect, I have to

sudo service networking restart

Do you need any more info? Just tell me.

[Christopher (soft-kristal)]

Same here. Shortly after booting, the Ethernet connects then drops. If I unplug the cable, service is restored through WIFI, all though that too peters out after a long period; often over an hour.

The Ethernet is the main problem, which is why I reported it as a separate bug.
