Need help installing a broadband box and setup

Hi, I’m looking for someone to install a new broadband box and get the home network up and running. I’ve got the modem, router, and some Ethernet cables, but I’m not confident configuring the network, Wi-Fi password, and basic security settings. The work includes connecting the box to the modem, verifying Wi-Fi coverage, setting up a guest network, and ensuring devices like a smart TV and laptop connect smoothly. Preference for a tidy install with minimal disruption, and guidance on any recommended firmware updates or optimization tips. I can be flexible on start time as long as the work finishes before the evening.
