12.04atherosbroadcomdriverswireless

I am using Dell Inspiron 5420 (14R 3rd gen). Wireless and wired works fine in Windows 7, but I do not get any in Ubuntu 12.04. lspci gives the following data:

02:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)
03:00.0 Ethernet controller: Atheros

I tried using this link answer: Drivers are not detected on my Dell Inspiron 5420 (14R 3rd generation)
but I get the following error :

bash: ./scripts/driver-select: Permission denied

I have a Dell Inspiron 5420 Laptop. I was struggling to install Wired Network drivers. The article above helped me in installing them. But after installing the wired network successfully, I tried to install Wireless Network drivers. I found out that I have "Broadcom Corporation Device 4365 (rev 01)" after typing lspci on the terminal.

I also tried the wireless setup guide given above, but was unable to install it, because it was saying that I have the i386 package installed and I cannot use amd64. After trying many different things, I tried to update my Ubuntu 12.04 to studio i386.

After all the updates were successfully installed. The system automatically asked me to install Broadcom Wireless, by clicking "yes" all my troubles were gone and now it is working smoothly.
