This could be related with the e1000e driver power management bug that was present in the 3.8 (raring) kernel. Basically, the ethernet card couldn't detect carrier signal if it was on deep sleep state (e.g., the laptop was on battery, not on AC).
Can you please confirm if you're still having this issue and if connecting the laptop to AC solves the problem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1152194 Title: Ethernet is showing up as disconnected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1152194/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
