Windows 7 - Wireless Connection Icon Disappeared!!!

I just used the internet last night, but when I awoke, I found that my
internet is not working...I saw that my screen icon with green signal bars
was missing and my PORT option in device manager is missing.  I am in my Navy
barracks connecting to a sprint navy wifi connection and tried everything I
could think of (even creating different types of connections and etc.)
PLEASE HELP!  THANK YOU

I'm presuming you've rebooted?
Does the wireless network adapter show up in Network Connections?
Check in device manager to make sure your wireless card is still showing up
as a network adapter. If not, try to scan for new hardware - if it's an
external wifi adapter, remove & reinsert it and try again.
