Wireless Network Connection 4 adapter

My laptop has stopped picking up the wireless signal that is in my room.  I know that the wireless signal is working fine because my roommates have been able to connect to it easily.  Also, I have made sure that I didn't accidently turn the wifi off on my computer.  When I used the troubleshoot option I was notified that there was a problem with the wireless network connection 4 adapter.  None of the options that were presented to fix it actually helped.  I checked and it said that all of my drivers are up to date and working properly.
