Wlan0 problems

[Ralph Sanchez]

Last night, i was continuing my tightening of security according to the
debain sites manual, and had pretty much finished with the securing
networks part...today, i start up my laptop and no wifi?? In the taskbar,
the wifi symbol has a question mark, hovering over it says
disconnected...but it is up in ifconfig, althougb next to up it says
Broadcast multicast (all caps) and it also says Link encap: ethernet, which
i dont think it did before. Help lol
