I own a HP Pavilion dv6626us (also known as the dv6625us entertainment laptop) AMD based laptop which previously had Fedora 8 running on a dedicated linux partition. Problem as with linux is always support for some hardware, in this case the laptop uses a broadcom 43xx based wifi network wireless card. Configuration takes a while using bcm43xx linux driver which can be obtained from here. I decided over the weekend to retry ubuntu using the live cd which l use on and off. I installed ubuntu from the live cd, and after rebooting and running a lengthy neccessary update, a pop up appeared suggesting l install 2 crucial non-licensed drivers for the broadcom nic and the Nvidia geoforce go 7150m graphics card. Once l did this, l had full wireless connectivity without the need for a reboot!
