Maybe this helps: I came from 13.10 to 14.04 (upgrade path) and after upgrading I was left with Kernel 3.11 (no upgrade to 3.13). The wireless network worked for me after a reboot.
Then I updated from Kernel 3.11 to the generic kernel 3.13 as supplied by 14.04 and after I rebooted I didn't have wireless network access anymore. And no network indicator. Could give a hint what is going on here... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308348 Title: network settings indicator missing from panel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxpanel/+bug/1308348/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
