I am using an HP Pavilion dv7 laptop that has wifi driver: Intel(R) Centrio(R) Wireless-N6150
(if you are not sure where I got this, it is in the "Device Manager"/ "Network Adapter"/. you need to boot windows 7 to see it.)
When the computer just start, wifi was working perfectly but then after a suspend, it keeps trying to connect and requesting authenticaiton without establishing a connection.
I have logged into Ubuntu and tried to create a file that tell system to unload and load the wifi adapters but that didn't work.
gksudo gedit /etc/pm/config.d/config SUSPEND_MODULES="iwlwifi"
The code above didn't do anything after i reboot and tested with a suspend. I am not sure if the "N6150" wireless driver name found in windows 7 has anything to do with this? but i just used "iwlwifi" as that was printed in the terminal for the name of the wifi network drive. (That's "mn-tool") I also tried to reset the adapter by terminal but that didn't even fix the problem. (that's rmod and modprobe)...
So if you guys have any tips on how to fix this problem, please help. I guess the simplest solution is to not having the computer suspend at all. But that is actually going to hurt your battery in the longrun, and heat up your computer, which potentially could dammage your hardwares. (I wonder if logging off or switching users without suspend would make this problem too or not....)
