Newbee stuck with no power to wireless card :(

[linuxlunatics]

Hello everybody.

I'm sorry for posting about something that has so many posts already, but I think my problem is somewhat specific/rare.

I have read quite a bit, and tried a few remedies, with no solution as yet.

After installing Ubuntu 12.04 on my HP Pavilion dv5000, my wireless card has no power running to it. I have pressed the button over and over again without it turning on. I have also installed the necessary drivers, as I tested all this before through a Wubi semi install before getting rid of Windows.

My wireless card is BCM4318 Airforce 1 54g if that helps.

I really really want to get better at using Linux but am becoming so frustrated! Why can't it just work??!!! hahaha

If anyone can help, I will be eternally grateful!!!

Thanks in advance.

Hi,

Please post outputs of -

lspci -nnk | grep -iA2 net
dmesg | grep -i firm

And can you get a temporary cable connection on the system ?

Check rfkill too:

rfkill list

Thanks for your reply.

I typed the code suggested into the terminal and got this -

lenny@lenny-System-Product-Name:~$ lspci -nnk | grep -iA2 net

Thanks for taking the time to help this utter noob out!

And I do have the machine connected to the internet via ethernet cable.
