I can connect at home, but not at work. I can see the SSID, but it won't connect. I don't see any errors using dmesg either when trying to connect.

I have been seeing this happen lately. Unfortunately the exact cause is unknown, however it seems as though there may be some issues with 802.11n compatibility. This worked for me (type these in a terminal):

# put down eth0 so it doesn't interfere
sudo ifconfig eth0 down

# disable n
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

Hopefully that helps. If it does, you'll have to type those in a terminal each time you reboot. I made it into a bash script that I just run when I first log in. You may wish to do the same.

EDIT:

Since you're using a Broadcom card, you may try adding pof's PPA and installing his fixed driver. I have never done this before myself, so I can't vouge for it's efficacy. However it may solve your problem.

sudo add-apt-repository ppa:poliva/pof
sudo apt-get update
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install broadcom-sta-dkms
