Sagemcom F@ST 3864 Modem - Wi-Fi Breaking down


Hi All


On joining Optus for NBN we were supplied a Sagemcom F@ST 3864 Modem in July 2017.

All was good.

Now however I have noticed for some time the wifi signal won't connect with my wifi devices

intermittently. Usually I restart the modem and it fixes itself.

Now it simply won't connect via wifi at all.

I have tried every reset known to man, including a factory reset but to no avail. I cannot get a wifi connection, unless I am 250 to 500 mm from the modem. Any further and nothing.


I need a new modem I thnk, so I'm asking how do I go about getting one from Optus ?
