How to Install Broadcom Wireless card (BCM43XX)
It seems a lot of people are having this problem, but none of the posted solutions have worked for me so far. My driver is installed and activated, I have tried removing and re-adding the network, and various other fixes. No networks were picked up on my first boot, the next day wireless worked fine, and since then it does not detect networks, and when I manually try to connect, it repeatedly asks for the password and does not connect. Here's my info:

Extra info, including syslog from when wireless was NOT working: http://pastebin.ubuntu.com/1203671/
Based on advice from another thread, I blacklisted mac80211, cfg80211, wl, lib80211_crypt_tkip, and lib80211. I then added modprobe brcm80211 to rc.local. Now when I boot up, nothing happens until I look at additional drivers. The STA driver is not enabled, and when I hit "activate," it comes up with an error message, but then immediately connects to the Internet without activating the driver. So I guess I just need to figure out how to make it do that automatically without having to go through trying to activate the driver. Here's what syslog looks like now: http://pastebin.ubuntu.com/1203702/
