Guest Wi-Fi that works beyond the lobby

The challenge on the ground

Corridor-mounted access points often look economical until fire doors, bathrooms and room partitions absorb the signal. At the same time, streaming guests share the uplink with reservations, voice, payment terminals and staff devices.

The difficult part is consistent service inside occupied bedrooms, not merely a strong signal at reception.

Inside the design

Use an MX75 at the property edge, an MS130-48P PoE switch and CW9172H wall-plate APs in the initial room layout. Use CW9172I APs for the lobby and restaurant. Keep property-management systems, staff access, payment equipment and guest traffic in separate networks.

Enable guest client isolation and agree how shared devices such as casting receivers are discovered without exposing other rooms. Count AP power requirements, uplink utilisation and the ISP circuit together.

Operating it day to day

Survey a representative occupied room and the rooms above and beside it before replicating the layout. Tune transmit power and channel reuse so AP density does not create avoidable contention.

Document the captive-portal support process and provide reception with a simple incident checklist: room, device, time and affected service. Schedule upgrades outside busy arrival periods and retain the previous configuration for rollback.

What to test before handover

1. Walk a video call from reception to sample rooms and record any interruptions.
2. Test casting discovery within one room and isolation from neighbouring rooms.
3. Load-test the guest service while the PMS and a test payment remain usable.
4. Confirm an unauthenticated guest cannot reach staff or device-management addresses.
