I have freshly installed 14.04 on an rlg laptop. after installing, the wifi is not working and I dont also have wired access to internet. the output of lspci -knn | grep Net -A2 is :
03:00.0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)
Subsystem: Hewlett-Packard Company Device [103c:1510]
Kernel driver in use: b43-pci-bridge
could you please help me activate the wifi?
