WiFi not working on HP ProBook 6550b

Asked by amorfis on 2011-02-03

I just installed Ubuntu on my new HP ProBook 6550b laptop. However, to my surprise, WiFi is not working. It is shown in lspci, but looks like not working. Looks like there are no WiFi networks, but I'm sure there is at least one. My home one. It works well on Windows, detects networks and connects.

Can you give the output of:

uname -a; lsb_release -a; echo; sudo lshw -C network


MANY wireless chips don't work out of the box as there are so many DIFFERENT chips which are completely unfeasible to accommodate. Some do work straight away, some require a little effort.

There is a chance it's one of those cheap Broadcom 43xx chips which are super easy to setup but the output will tell us.

Yes, it is Broadcom 4313. Outputs below. I bought this laptop because it is certified to work with ubuntu (http://www.ubuntu.com/certification/hardware/201101-6954). There are even no Certification Notes.

Shows how you can use the liveCD to install the driver, it is available you just need to kick it off. The firmware in the hardware is proprietary so cannot be included in the CD but the tool to create the driver can be included.

Okay so i installed Ubuntu within windows. Everything works fine except for the OS not being able to connect to wifi. I tried to look up some stuff and installed some driver and i don't even know what else i did. I have a Compaq Presario CQ56-110US, it works when i plug in my Ethernet cable but i need the wifi working :(. Can any one help?
