8266 after WAKE_RF_DISABLED

Hi !

to minimize power usage at wake-up I use

ESP.deepSleep(sleepDurat, WAKE_RF_DISABLED);

but... when, sometimes, I need wifi I have to start the modem and I only find

ESP.deepSleep(1, WAKE_RF_DEFAULT);

not really practical...

Is it a way to restart the modem without reseting the ESP8266 ?
Is it a "status" giving "modem disabled" ?

Thx
