I just bought a HP Pavilion G4-1212TU laptop and put Ubuntu 11.10 on it. WiFi works badly. It can usually connect (though showing a lower strength level than when the laptop is in Windows) but sometimes immediately, sometimes after a while, the connection becomes so bad as to be unusable.

That is, the connection strength shows the same number of bars, but TCP/IP requests seem to fail or packets lost.

HP doesn't seem to have any LINUX/Ubuntu drivers for the WiFi for this laptop.

User ts3 over at Ubuntu Forums wrote a solution which worked for me, finally, after so long a struggle. So if you're facing the same problem as me, check it out at http://ubuntuforums.org/showthread.php?t=1889170

Here's his summary:

  1. The b-43 installer does not support BCM4313 (4727)
  2. The bcmwl-kernel-source driver (found in the Ubuntu Software Center) supports it but first one needs to make sure that
    1. b43 and the option to activate the STA Broadcom drivers through System Settings -> Additional Drivers are uninstalled/disabled
    2. that those drivers (b43, bcma, brcsmac) are blacklisted and
    3. that the wl driver that works is NOT blacklisted

See the link for details.

In my HP nx 7300 this worked (from terminal):

sudo apt-get purge broadcom-sta-common broadcom-sta-source bcmwl-kernel-source ; sudo apt-get install b43-fwcutter firmware-b43-installer

Maybe you will need reboot. Good luck!
