I think I've narrowed down my Broadcom BCM4318 wifi problem to a problem turning on the hardware. The wifi LED light is always on. Fn-F2 key should toggle wifi device on/off (Dell Inspiron 6000) but it does nothing.
I'm following the "WirelessTroubleShootingGuide" at
The driver and everything checks out until I get to this part of the guide:
An abbreviated output from "sudo lshw -C network" on my system:4.2.5. Driver looks ok, device disabled
* Newer laptops come with features to disable the wireless radio to save battery...
Usually this is apparent by running the lshw command you see *-network:1 DISABLED or wireless=radio off
An abbreviated output from dmesg:*-network:1

A little while back, I was getting a long list of wifi signals from the NetworkManager applet. The connections were fine. WEP encryption was fine. I used the native driver BCM43xx without problems. It broke with a kernel update while running Intrepid, and does not work with my Jaunty install.Look at the LaptopTestingTeam page on the team wiki to see if your laptop is listed with any information.
Do a Google search using terms such as manufacture, model, linux, wireless, enable, button, radio....etc. When searching and finding similar pages that don't help, use words that are used in those pages to help you search.
Go to the Ubuntu forums and ask, maybe someone else has the same laptop and knows the work around.
Am I on the right track? Any ideas?
