Why guest Wi‑Fi must be separate
Visitors, contractors, and IoT on the same network as finance PCs is a common breach path. Guest SSIDs should land on an isolated VLAN or subnet with internet-only access — no routes to internal servers or printers.
Simple architecture
Business-grade access points support multiple SSIDs mapped to VLANs. Staff SSID uses WPA3 or WPA2-Enterprise (802.1X) where possible; guest SSID uses a daily passphrase or captive portal with acceptable-use terms.
Bandwidth and abuse
Rate-limit guest traffic so Teams calls on the staff VLAN stay stable. Log and block peer-to-peer if your ISP complains. Review connected clients occasionally — forgotten guest passwords get shared.
Melbourne office practicalities
Reception areas, warehouses, and client meeting rooms all need coverage without bleeding into the street. A quick site survey beats buying one oversized consumer router and hoping.
