Need help installing a home internet box and configuring Wi‑Fi

Hi there, I’m looking for someone to help install a new broadband box and get my home Wi‑Fi up and running. I have a standard UK/Ireland modem from my provider and a couple of devices (laptop, smartphone, smart speaker). I’d like basic setup: connect the box to the modem, configure the network name (SSID) and password, ensure the wireless signal covers a small two‑bedroom apartment, and run a quick speed test. If possible, please verify firewall settings and advise on optimal security options. I’m hoping for a friendly, patient installer who can explain steps as they go. I’m flexible on timing, prefer a weekday morning.
