Hello today I opened my laptop same way as almost every work day in year. But I couldn't connect to Wifi. First I tried to restart my laptop but didnt wok. Then i tried to restart wifi and still the same. I did both but still couldnt connect. Wifi worked on every other device in my house so the problem was in my laptop. I reinstalled all my network gadgets (dont know what those are called in Engilsh) but didnt work. Then I opened my back shield and tried to Whatblow away dust after that it connected but i had to restart because i couldnt open chrome. After restart couldnt connect again. What can I do. I need my laptop almost daily for school and other things.
