[ubuntu] Dell Insperion 1720 won't stay connected after upgrade 12.04

http://ubuntuforums.org – So I've been reading, and have not been able to find a fix for this. The problem is that when I connect to a secured network, it keep getting kicked off and asked for my routers Key every ten to fifteen seconds. I can however connect to a non secured network, and stay connected with out any problems. I am currently connected via wireless tether through my droid. Here are some codes that i copied and pasted into the terminal. Mind you I know what none of this means. xbostonirishx@linux-box-1720:~$ rfkill list all 0: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no 1: (Hardware)
