No wireless option available in 12.10

Question

On my friend's Ubuntu 12.10 (Unity) laptop, there is no longer an option to connect to a wireless network. It used to work. He doesn't know what caused it to go away, but does anyone know how to get it back?

More info:

See the screenshots below
No wlan things show up when you run iwconfig
Laptop is HP ProBook 6550b

@user84277: I updated the question to include the laptop model. But I'm wondering why you believe the hardware might be relevant if the wireless used to work? — Ian Hincks, Nov 19 '12 at 18:44
@IanHincks because some wireless devices need drivers that Ubuntu does not come with by default. — RolandiXor, Nov 19 '12 at 20:49

Your laptop model appears to have a Broadcom wireless chipset.

open terminal and type what is shown below

sudo apt-get purge broadcom-sta-common broadcom-sta-source bcmwl-kernel-source

then type

sudo apt-get install b43-fwcutter firmware-b43-installer

Restart your computer after the command is completed and your wireless will start to work :D

@DavidFoerster The laptop model the OP said they had appears to have a Broadcom b4313 chip. Although it would be better if the reasoning in this answer were explained explicitly, I think the inference about the wireless chipset is reasonable. I think we can close this as a duplicate of Installing Broadcom Wireless Drivers. – Eliah Kagan Apr 01 '18 at 02:13
