Establish a connection to your router's web interface
If you want to change router settings, you need to establish a connection to the router web interface.
Open an internet browser and go to http://Optus.AC800S
Click the field below "Sign In" and key in your password for your router.
The default password is password.
Click Sign In.
Click Enter PIN.
Click the field next to "Enter SIM PIN" and key in your PIN. The default PIN is 0000.
If an incorrect PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. The PUK can be obtained by contacting Customer Service. Please note: If an incorrect PUK is entered ten times in a row, your SIM is blocked permanently. In this case, you'll need a new SIM from Optus.
