wi-fi managers

Does anyone know about, or know of a good Wi-fi manager that you can turn on / off your wi-fi from the phone desk top, allows you to switch between signals when one becomes poor, shows the signal strength, name of the wi-fi signal,
and allows in permissions your phone to go to sleep, and doesn;t rip a hole in your battery power?
Had a signal strength widget, that when in a known wi-fi area didn't work so uninstalled that. So now looking for a manger with basically everything on it, that works.
Appreciate you thoughts...

One further question..
Where we live our wi-fi signal in this area is rather poor, and when in a poor wi-fi area, the signal keeps being disconnected, and you have to manually re-connect. Is there any kind of app to help keep the wi-fi connected? if there is an app like that, will it prevent my phone from going to sleep when I turn the wi-fi signal off??
Appreciate any help available.. thanks-
