so I've purchased this wifi extender and the wifi keeps disconnecting every day a couple of times no matter if the boost mode is on auto or 5ghz increase or 2.4. my ISP modem seems to have a better 2.4 range then with this ( technicolor model cga4236tch1) the firmware is the latest and I heard it works worse then and factory resetting doesn't roll back the firmware upgrade. what should I do? dear God please help
