Hi @RickyBobby, sorry to hear you're having some troubles with your Internet service.
Have you checked the Network Status page to see if there are any outages in your area may be affecting your service? Simply click on Fixed Outages and enter your full address into the search bar and if there are any outages, you will see them reported.
May I suggest having a look at My Optus Service Is Not Working: Troubleshooting Index for steps to help you get the best connectivity for your service. Just select the Internet connection type you have.
Can you please try turning off both the NCD (white NBN box), if you have one, and the modem by the power switch, waiting 10 minutes and then turning on the NCD first, then turning on the modem.
If you're still having issues with connecting please reach out to us by a private message via our Social Media pages (official Optus Facebook page or Twitter page) where we'll be able to grab your details securely and take a closer look for you.
