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
