I have been able to connect to the internet via WiFi in the past, but lately it won't let me. My WiFi connection is shown in Green and there is also a green checkmark to the right of it. The WiFi logo is also showing on the top right of the main screen as is the name of the connection on the top center of the screen. Anything I type in says that " it could not connect to the internet at this time, try again later". What could have happened that would prevent me from accessing the internet through this connection anymore? How can I fix it?
