Hi,
I emailed the support regarding my intermittent disconnection of my DIR 615 router. They advised me to upgrade my firmware and they are giving the firmware of 625. I replied to them asking for a confirmation why 625 if I have 615, but every tech support did not answer my question instead, they are giving the procedure on how to upgrade my firmware.
I would like to ask, is this possble? Using firmware for DIR625 to DIR615?
