Can''t find Wi-Fi network on my AT&T Samsung Galaxy S4
I have an AT&T Samsung Galaxy S4 (SGH I337), I suppose it is unlocked because I'm in Cuba and of course AT&T has no presence here. The problem is no Wi-Fi network ever shows up (Maybe as a result of unlocking??). I can turn Wi-Fi on and off but my home network doesn't show up (or any other for that matter, I've tried at public places). The problem is not in the rooter because the rest of my family phones work good, it seems to be specific to Samsung phones. Similarly when I use sharing apps like Zapya, I have to create first and wait for the other to connect, otherwise I'm not able to join my friend's group. This has to do with Wi-Fi since Zapya uses it for sharing.
Any help will be appreciated, thanks
