Internet problems on my Lenovo

Hello, yesterday I was using my computer and I shut it off. When I came back a few hours later, the wifi couldn't connect, and, unlike most times life this, it displayed an ethernet symbol with a red 'x' opposed to the normal wireless symbol with an 'x'. My computer stopped connecting to any wireless, though works fine with ethernet.

It is a Lenovo Ideapad with Windows 8

I've tried rebooting (I'm clueless, but not that clueless), updating the OS, uninstalling and reinstalling the computer's drivers along with some more far-fetched stuff (I got desperate) such as removing the battery, waiting a few hours, and plugging it back in, but nothing has worked.

If anyone can help, that would be amazing, thanks!
