Need help setting up a broadband router and box installation

Hi there, I recently moved into a new apartment in Ireland and need someone to install and configure the new broadband box. I have the modem, router, and any required cables, but I’m not confident with the setup or network security. The job includes connecting the router, ensuring Wi-Fi is broadcasted, configuring basic security (strong WPA2/WPA3), and testing the internet connection. If possible, please also check for any firmware updates and explain the steps in simple terms. I’d prefer a morning slot and can provide access to the apartment, plus access to the landlord’s installation guide if needed.
