Big houses in Sydney rarely have a coverage problem — they have a coherence problem: several routers bolted on over the years, each with its own WiFi name, password and blind spots.
A two-storey house with wings — around 16 rooms including living areas — ran three routers from three brands (Huawei, TP-Link, a ZTE modem-router) in three rooms. Phones didn't roam between them, security cameras were attached to different routers on different segments so they couldn't be viewed in one app, and every guest needed three passwords.
- Modem set to bridge mode; one main router handles PPPoE.
- Existing Ethernet reused as wired backhaul for mesh satellites — the most stable form of mesh.
- One SSID across the whole house with seamless roaming; all cameras on one segment, viewable in one app.
For a separate client with a 1,200sqm garden and 300sqm interior, the same design carried WiFi to the far corners of the yard. (That job also involved wrangling five different account passwords across the ISP, app and hardware — a uniquely Australian sport.)
