I was playing around with the settings file because i don't have a
client app implemented yet. I was not aware of the .config files.

The wext driver is the one in use. The command that i specified is the
actual command in use without the '-n -d' options.

I had not noticed the patch. Applied now and the crash issue is fixed.
But i noticed an issue with the dnsproxy that i have mentioned in
response to the patch.

The Wifi chip has a RTL8192cu chip. They actually have an updated
driver released for the chip. Will see if there are any improvements
after updating the driver to the latest version. However i am not
completely sure if this is an issue with the wifi chip. What i have
noticed is that there is not problem connecting to my home wifi
network at boot up. But the wifi there is some issue while connecting
to the test wifi network i setup at work. Maybe something to do with
the router.
