i installed ubuntu lucid LTS on my new lenovo ideapad (s10-3s) recently.
i think i didn’t enable restricted drivers while installing and becos of which wireless won’t work.
1. plugged my netbook to the wired network.
sudo apt-get remove –purge bcmwl-modaliases
to remove existing broadcom support.
2. enabled all the sources.
System -> Update Manager -> Settings
3. and reinstalled broadcom drivers again.
sudo apt-get install bcmwl-modaliases broadcom-sta-common
4. now, wireless still won’t work right away but we are close.
clicked on the network connections applet on the panel and its said that restricted drivers are available and that i can install them. oh, please. the driver is downloaded and its all done.
