After suspending and resuming my machine, my wireless networking fails to reconnect. Running nmcli nm shows the following:

Before:

RUNNING         STATE           WIFI-HARDWARE   WIFI       WWAN-HARDWARE   WWAN      
running         connected       enabled         enabled    enabled         disabled

After:

RUNNING         STATE           WIFI-HARDWARE   WIFI       WWAN-HARDWARE   WWAN      
running         disconnected    enabled         enabled    enabled         enabled

Even running sudo service network-manager restart fails to do anything. Only by restarting the machine have I been able to reconnect.

EDIT: More info

Hardware:
The wireless adapter is a Rosewill RNX-N180UBE.
It is attached via USB to an Asus H87I-Plus motherboard. (This is a custom-built PC)

Running lsusb shows the following for the adapter:
Bus 003 Device 002: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter

Please edit your question to add more information about your hardware (laptop model, wifi card model, etc) – hmayag May 22 '14 at 21:01
Iǘe got the same problem with an external usb wifi dongle. With me it helps to unplug the dongle and plug it back in. I have no other current solution to this though. – kramer65 May 31 '14 at 14:13
