I recently installed Ubuntu 12.10 on my Dell inspiron 5720.
sudo lshw -C network says :

i tried troubleshooting for the same by browsing the forum.. but the debs mentioned are either for amd 64 or i3 32 bit. i checked http://ubuntuforums.org/showthread.php?t=2078800 but it dint help in anyway either. my laptop is an i5 64 bit. i tried the i3 32 bit dev and while installing, it said the package is of bad quality and is not recommended for installation. i installed anyway but it dint make any difference
moreover, i think while trying to install the add-ons for ndisgtk ,it threw error messages for the kernel pack. im losing my mind over this @_@ PS im completely new to linux
Thanks for the response. Unfortunately neither of those two worked out for me. when i tried modprobe nothing really happened after reboot.and i just searched for the proprietary driver and looks like there are none for bcm43142
