wifi suspend issues

Wifi works great, except resuming from Suspend

Troubleshooting: Does it work if you click on the network widget in the taskbar, then disconnect and reconnect to the access point? Some laptops would exhibit this symptom--it would say it was connected after the resume, but no bits would come over the connection until the above was executed. steveo's fix was to add the wi-fi driver module to a file that unloads it before suspend and reloads it after resume.

From a command line use

inxi -n

And identify the device that provides wireless capability. In this example we get: 

Card-2: Broadcom Limited BCM4322 802.11a/b/g/n Wireless LAN Controller driver: wl

So the driver we need to work with is called "wl"

Create a new text file called "config" with these contents:

SUSPEND_MODULES="wl"

Make sure you have a newline after the line with text in it.

and copy it to /etc/pm/config.d using:

sudo cp config /etc/pm/config.d
