I installed fresh copy of ubunti 14.04 LTS and Ubuntu use my entire disk but i cannot connect to wifi i see enable wifi button is in grey color
rfkill list all
shows
phy0: Wireless LAN
Soft blocked : no
Hard blocked : yes
I tried
rfkill unblock all
but problem remain same
i also did
lspci -nnk | grep -iA2 net
Both Network Controller and Ethernet Controller uses kernel driver so i think it might not be a driver problem ?
lspci -knn | grep Net -A2
terminal command.
