I have a shiny new HP Pavilion g series laptop (g7). The very first boot of the system was a gparted-live usb to split out some space for Ubuntu. The second was a 12.04 live usb.
Mostly it is working extremely well. The exception is WiFi connectivity. It seems to connect at first, but then after anywhere from 30 minutes to four hours I lose connection and cannot reconnect until I reboot the router. Sometimes an RFKill block and unblock will fix it. And yesterday I saw a suggestion to remove the NetworkManager.conf file. The latter seems to have extended the time to failure to hours rather than minutes.
What should my next steps be?
