The android phone can't scan the wifi network around.

[Android Central Question]

My phone is still used everyday but until today, it disconnects to wifi and when I go to the wifi to check it does not show any wifi network at all! I tried scanning on another phone and still got wifi.
I tried rebooting the phone and reinstalling the phone, but it still does not fix it!
Please help me solve it!
