Where did my wireless connections go?

http://askubuntu.com – I'm running Ubuntu 12.04 LTS on a Dell Lattitude 620 laptop with a Broadcom 4331 card and a Motorola Surfboard SBG6580. I'm listing all of this stuff, because I'm really not sure which part the problem is coming from. When my cable internet service was activated, I set up a wireless network and was able to connect to it, however, when I shut down my computer and restarted it, it no longer registers a wireless connection, not only in the network manager applet, but also the Network section of the system settings. My wireless switch in BIOS is on. I've tried killall and reinstating in terminal. (HowTos)
