I need some help. My internet was working fine and all of a sudden I am not able to open a web page. I went through some of the steps you recommended to other users, such as adding DNS 18.104.22.168 & 22.214.171.124 to test internet connection but I still can't get a webpage to open up. I ran diagnostics and my internet connection is fine. When I connect the ehternet to the computer it connects fine, but I can't get the wifi to work. Can you help?
