How to fix “SuccessSuccess” Wi-Fi issue on MacOS X Mavericks temporally

This issue is caused because Apple's autologin url polling is failing. That url is returning plain html characters, so the OS thinks it didn't connect properly to the Wi-Fi network.

To solve it until Apple fix that polling website, you can change it to this one (it is also official from Apple):

1- Open Terminal

2- Type:

    sudo nano /Library/Preferences/SystemConfiguration/CaptiveNetworkSupport/Settings.plist

3- Edit the line 8 by changing the url:

    OLD: http://www.apple.com/library/test/success.html
    NEW: http://captive.apple.com

4- Press `CONTROL` + `X`, then type `Y`, then `ENTER`. 5- Reboot
