Bug Description
The wired controller is disabled (grayed out so it can't be clicked) in the nm-applet after resuming the laptop from suspend. Attempting to secure a DHCP offer via terminal (e.g., 'sudo dhclient eth0') fails, though the network lights on the hardware are physically on.
To get the networking to function again I need to reload the kernel drivers by doing the following:
sudo modprobe -r et131x
sudo modprobe et131x
I have a Ethernet controller: Agere Systems ET-131x PCI-E Ethernet Controller (rev 02)

I too tested this issue in my acert laptop (08:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02). The bug happens at around 1/3 of the suspends/resumes and if I do
ifconfig
I only see the "lo" interface. If I connect my cell-phone with a usb cable to start my gprs Internet connection, nm-applet doesn't do anything and the usb0 interface doesn't appear. If I do
ifconfig usb0
usb0 appears but with no ip (nm-applet still remains in network disabled state).
To resume the normal state of my PC I rebooted it (I haven't tried any "rmod/modprobe")
