Having trouble with wifi on my laptop

edit

You need to give us more information, open your terminal and issue this command

lspci |grep Wire

Please paste the output here so we know what chipset you have and the know what you need to do.

Good Luck

Thanks for looking into the problem. I did not get any when I tried this command

lspci | grep Wire

Anything else I can try here? Do you need output of just

lspci

if lspci command is not installed you should install it lspci should give you some output

lspci is already installed. but it doesn't give any output with grep. It gives me output when I just type 'lspci'. I get below output.
