I've just installed Ubuntu 13.04 in an old HP Pavilion dv2419us. The problem is, Ubuntu doesn't detect the wireless card. But it works fine in Windows 7.

The following command returns nothing!

lspci -vvnn | grep 14e4

And the lspci output is:

The command lspci -nn | grep 0280 gives no output.

Any suggestion regarding this?

Please edit your question to add the details of your wireless card from: lspci -nn | grep 0280 –  chili555 Nov 6 '13 at 15:24
    
lspci -nn | grep 0280 doesn't give me anything. And the wireless button is not hard blocked. –  maqtanim Nov 6 '13 at 15:30
