@Deb_1 I was unable to find a proper way to DM you, so I'm posting the method here.
Follow the below mentioned method carefully. In case you're unable to understand a step, ask me about it first before proceeding with the procedure.
Step 1: Connect your ONU directly to your PC via an ethernet cable.
Step 2: Go to adapter options under network settings, select your ethernet adapter and then change the settings as follows, by clicking on "use the following IP" :
IP ADDRESS : 192.168.1.8
SUBNET: 255.255.255.0
GATEWAY: 192.168.1.4
Set the
DNS server 1 to 8.8.8.8.
Click apply to save the changes.
Step 3: Make sure all other adapters (if any) are disabled except your ethernet adapter.
Step 4: Restart/Power Cycle your ONU.
Step 5: Once the ONU has booted up, open any browser and type in the following address:
192.168.1.1
Step 6: Enter the following credentials (default):
Username: admin
Password: admin
Once you're done with the settings, don't forget to revert back the changes you made to your PC's network settings, i.e, enable any adapters that you might have disabled and change IPv4 settings of your ethernet adapter back to automatic.
