My superhub 3 is playing up...again...had issues with it losing connection slow speeds and disconnecting the 2.4 band etc took advice and done a factory reset which appeared to cure the problems..now a month later it has started again, the 2.4 side drops out and the range has suddenly dropped ..this band controls the house smart devises including heating Alexa and smart plugs. I don't want to keep rebooting the router especially in the middle off the night to controllivht or heating ..is it time for a new router?? PS I have no probs with the 5 ghz band and the speeds are fine
