I used to have deco x80-5g on wireless but now I switched to fiber as soon as the fiber was available , the modem worked solid and perfect with fiber as well until last month it started to drop down few times a day (the light turned to red ) ,if I re-started the modem then it works again, it is really annoying me ,it is a good quality high spec modem I don't want to throw it away . Anyone has similar experience ? the fiber service is still with ONENZ .
