This issue is being experienced on a Lenovo T430 laptop running 13.10
with the latest updates. It has been happening since roughly the time I
upgraded to 13.10, but was not happening with 13.03 and the 3.11 kernel.
After resuming from suspend, many times NetworkManager will not list any
connections, will not connect to wired networks, and will only show
"Network Enabled" unchecked in the drop-down menu.
NetworkManager Status:
tcameron@HOSTNAME:~$ nmcli nm status
RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN
running asleep enabled enabled enabled
disabled
Using nmcli to set the sleep state to false re-enables networking
manually.
tcameron@HOSTNAME:~$ nmcli nm sleep false
RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN
running connected enabled enabled enabled
enabled
tcameron@HOSTNAME:~$ nmcli nm status
