Wi-Fi on your wireless device may have problems for many reasons, to verify that the inconvenience to then know what the solution of it is due, you step a list of reasons why the Wi-Fi could not operate and how to solve each problem:

1-Log, possibly at a different frequency. Some routers offer free 5Ghz and 2.4Ghz, simply change from one to another.
2-Verify that you have your network drivers properly installed (reinstall it Network Drivers).
3-Check you do not have a wireless network card disabled.
4-Go to advanced menu options and uncheck Wi-Fi options "network notification On" and "automatically connect".
