I Have had my laptop for about 3ish years now, and didn't use it for about a 1 year may 2015 to january 2016 and about a week or two ago my wifi stopped working and I couldn't turn the wifi on or off. it stopped working about a day after I got an update for my computer, and about three days after I installed google chrome on my computer. I have tried restarting my computer/I turned it off for about 5 minutes and then turned it back on again and I was still unable to turn the wifi on or off, even when I had air plane on or off. My computer is a ASUS T100 10-Inch Laptop with window 8 I think.
