How to design a stable network: topology, guest VLANs, access points, fibre, backup internet, and monitoring — in plain language.
In Bali, guest reviews often mention one thing that has nothing to do with the room or the food: Wi-Fi. Offices are the same — card terminals, POS apps, CCTV, and online meetings all depend on the network. When the network stalls, the whole operation stalls with it.
The internet is the toll road into the city, the router/firewall is the toll gate, the switch is the main junction, and the access point (AP) is the local street that reaches each room. A bottleneck at any point is felt everywhere — so the plan has to be complete.
| Component | Function | Practical note |
|---|---|---|
| Main + backup internet | Connection to the outside | Use two different providers with automatic failover |
| Firewall / router | Gateway & protection | Set bandwidth limits and block dangerous sites |
| Core & access switches | Cable distribution | Choose ones that support VLANs and PoE for APs/CCTV |
| Access points | Wi-Fi signal | Enterprise class, centrally managed, roaming support |
| Copper & fibre cabling | The backbone | Fibre between buildings or over long distances |
A VLAN (Virtual LAN) splits one physical network into several logical networks. At minimum, separate three: guests, staff/office, and devices (CCTV, card terminals, smart TVs). That way guests can't "see" the cashier's computer, and guest streaming doesn't slow down the reservation system.
Wi-Fi 6/6E and Wi-Fi 7 increase capacity for crowded areas, while cloud-based network management lets monitoring and updates happen from anywhere. The network is also becoming a business "sensor": visit and footfall data can help operations and marketing, as long as it's handled according to personal data protection principles.
It depends on floor area, wall materials, and the number of simultaneous users — not just the number of rooms. That's why a site survey matters: on-site signal measurements determine where APs go and how many are needed, so there are no dead spots and no APs interfering with each other.
For a few users it may be, but home routers generally don't support seamless roaming, VLANs, or central management. As soon as there is more than one floor or an outdoor area, business-class APs are usually far more stable and easier to maintain.
If payments, reservations, or operations depend on the internet, yes. Use a different provider over a different physical route, then set up automatic failover on the router so the switch happens without staff involvement.
Put it on its own VLAN, enable client isolation, limit bandwidth per device, and use a login page (captive portal) if needed. Never use the same password for guest Wi-Fi and the office network.
