I have found that, if you keep a device connected to wifi for a long time without using it, the connection will drop off. I think it may have to do with the device, not your service. Sometimes, I need to turn off the device and reboot to restore the connection. You can also disconnect and reconnect the wifi on the device using the settings connection feature. But, I don't think you can expect any internet service to be 100 percent reliable. I have never needed an extender to improve the wifi range.
