Hi,
I just installed CentOS 6.6 on my HP Pavilion DM1 laptop. The wireless card is only poorly supported in the default setup, so I decided to write an installation script for the Linux-STA driver, which works perfectly.
https://github.com/kikinovak/centos/blob/master/6.x/broadcom-sta/broadcom-st...
Grab the files:
# git clone https://github.com/kikinovak/centos
Run the script:
# cd centos/6.x/broadcom-sta # broadcom-sta.sh
Reboot and you're ready to go.
Cheers,
Niki
