My laptop won't connect to ANY wi-fi at all

[vyeoh28]

I bought a HP laptop and seemed to cannot work at any wi-fi at all. I brought my laptop to the technician and they said the wi-fi is now perfectly fine and when i tried it at home it still can't connect to the wi-fi. Luckily i can connect to the internet with an ethernet cable. I also tried to solve this problem like plugging out the battery then put it back in,etc but those don't work, I really need my laptop to connect to wi-fis because I need to do tasks at school and bring it to other places. ( I already bought my laptop for two years)

Can you connect to any WiFi outside of your home, like a coffee shop or friends house?
