Welcome to Optus with the crappy Sagem modem. We have been fighting with WIFI ever since they changed from the Netgear modem to the junk one. Have a look if Wifi is switched on in Wifi Management, Station and password match, all the usual stuff
After it sort of works and the frustration sets in we do these:
We bought a WIFI booster, helped a little bit.
Reset the modem regularly, 2 adults, 2 kids with phones, laptops, playstations etc on Wifi, it just gets snowed under. We generally reset when Netflix stops streaming, Optus streaming seldom works, we use the mobile for that.
Play around with the chanel, doesn't do much, but makes me feel like I am doing something to improve it
did you received a new modem with the new NBN connection? if yes, then is the devices connected to the new Wifi modem?
This is for the white Optus YES Sagem modem.
Wifi is switched on in Wifi Management (check with 192.168.0.1 in your browser address bar)
The WiFi light on the modem should flicker when activated
Search on your Tele for available Networks
Connect to yours, the name of your Network is on the fridge magnet, something like OPTUS_****** if still default
Enter password from fridge magnet
Should connect now, if not ring Optus, we had a couple of faulty modems before Wifi started sort of working.
contact optus technical support for assistance.
Here are some steps I would recommend.
1. Direct cable connection to the modem via one of the yellow port, check if internet is actually working.
2. connect the same computer via wifi, check internet.
3. Connect a mobile phone to the wifi, check internet.
4. check that your icloud wifi password is updated to the new modem's wifi passphase.
