I have a Raspberry Pi that I need it to remain connected to my WiFi constantly (at least as soon as the WiFI becomes available). In practice, however, I have noticed that when there are problems with the WiFi, it gets disconnected and it takes quite a lot of time to reconnect (e.g. 1 minute). Even worst, there are some rare occasions when the RPi after disconnecting, it does not try to reconnect back at all.
My question is, is there any CRON-driven (and lightweight hopefully) script that will force (at second granularity) the RPi since its very boot, to be trying to reconnect (in case it is not connected) to a specific WiFi AP?
I have sudo iwconfig wlan0 power off in /etc/rc.local but the problem remains.
My RPi is:
