Broadband router fit up

Hello, I'm looking for a freelancer to help with getting my fiber-optic broadband router set up. I'm a beginner when it comes to router setup, so I need someone with the expertise to walk me through the steps so I can get up and running. The router I'm currently using is a fiber-optic model, and I just need help with the initial setup and not any troubleshooting. Please let me know if you're able to assist.
