Cannot connect to Internet

My background photo would be removed each time I switched on my computer. I was asked to type in something and click hidden items. I restarted the computer before going to the next phase and I can't remember what I typed except that it started with fn. Now my computer won't connect to the Internet and my task bar is different. Please help. Thank you.
