I am not able to connect wifi in my laptop with Ubuntu 16.04 LTS
Can some one let me know what could be the problem?
How can I check if my system does not have some software necessary for connecting wifi?
As suggested here I am giving the information in wireless-info.txt file.

any help to fix this problem would be appreciated.
rfkill
the wireless adapter on you system is disabled through a hardware switch and/or vendor-specific kernel module. Could you please (1) search and enable the wireless switch on your laptop computer and (2) runsudo modprobe -r hp_wmi wmi
and thenrfkill list
and include the output of the latter (or both if the former prints an error) into your question? Thanks.
