I can't connect to wifi. Wifi is turned on and my router is working as other devices are connected

Solution
Disable the wifi security option in the router and try again, so you can connect without password. If it works now, change the password to a simple one. Sometimes special characters won´t work

Sometimes antivirus applications or firewalls can be the problem

eventually reinstall wifi drivers for your laptop
