Need help installing a Wi‑Fi box and setting up network

I'm looking for a reliable technician to install a new Wi‑Fi box and configure the home network. The job includes replacing the existing router, connecting the modem, setting up the SSID and password, enabling guest access, and ensuring a secure connection across the house. Please confirm compatibility with my broadband provider, run a speed test, and help place the box in a central location for optimal coverage. If possible, provide tips on improving the Wi‑Fi signal in upstairs rooms. I’m flexible on the start time but would prefer a weekday morning.
