I recently installed Ubuntu 12.10 in my laptop (Dell Inspiron 14Z 5432) alongside Windows. But both my WiFi and wired connections are not working. It's working fine in Windows.
I tried downloading the compact wireless file and followed these steps:
tar -xvf compat-wireless-2012-07-03-p.tar.bz2 cd compat-wireless-2012-07-03-p scripts/driver-select alx make sudo make install sudo modprobe alx
But I get a report of error and it's still not working.
