Random disconnection at almost fixed interval
My router is forcingly disconnecting few of my devices after a few hours duration. So it will always be .XX minute of the hour, if I reboot the router this .XX minute will then change. The number of hours until each disconnection is not exactly fixed, few to 10 of hours.
I have checked by DHCP lease renewal, it is not due to that as it is set to 7 days.
I can see from my router log, prior to the disconnection, the router received some request from STARHUB. The disconnection is temporary and takes a minute to reconnect but yet it is very disruptive due to its multiple occurence per day. Please advise.
