I dont see any wireless option on there. I have googled enough and this seems to be my last resort. Since not much familiar with the command line tool of ubuntu, kindly take me through it step by step. I'll keep updating.

Also, I tried

sudo lshw -C network

and the output is

sudo lshw -C network

Kindly help.

for knowing the wifi card do:
lspci | grep -i network
it must be Broadcom BCM4312, then look for the driver and install it

[karan093]

lspci | grep -i network

It does not output anything.

[benzarti]

Check in the bios for a hardware switch like "Wireless enabled".

[karan093]

How do I do that?

[karan093]

So i restarted and wireless enable was already checked in BIOS.

[benzarti]

Restart the computer. At the very beginning you must see press "F2 to enter setup" and then change the option CAREFULLY.

[benzarti]

Other hardware switch is with fn key. Check the manual of your laptop on how to enable/disable Wifi with the fn key.

Please show the outputs of:

lspci -nnk | grep -iA2 net
lsusb
pccardctl info
lsmod
iwconfig
rfkill list
