Call the provider first for activation, outages and faults in the carrier network. Use an independent technician when the provider says the problem is inside the premises, remote scripts have not isolated the cause, or you need evidence separating the NBN service from the router, WiFi, device or internal setup.

套餐激活、区域故障和运营商网络问题应先找运营商。若运营商说故障在屋内、远程排查无法定位，或你需要证据区分 NBN、路由器、WiFi、设备和屋内设置，则适合找独立技师。

A useful visit separates the service into layers: connection box or wall service, router and authentication, Ethernet, WiFi coverage and interference, then individual devices and applications. The result should identify the failing layer rather than simply replace hardware.

有效的上门检查会按层拆分：接入盒或墙上线、路由与认证、有线、WiFi 覆盖和干扰，最后到具体设备与应用。结论应指出故障层级，而不是直接猜着换设备。

Often, yes. We first compare Ethernet with WiFi and measure the problem room. Coverage changes may fix wireless jitter, but high ping can also come from upload saturation, ISP routing or a distant game server, so those causes are tested separately.

通常可以。先比较有线和 WiFi，并实测问题房间。覆盖改造可能解决无线抖动，但高 Ping 也可能来自上传占满、运营商路由或海外服务器，因此会分别排查。

Regulated fixed communications cabling must be performed or directly supervised by an appropriately registered cabler. In NSW, selling, installing, maintaining or repairing security equipment such as CCTV generally requires the relevant security licence. We scope ordinary network work separately and allocate regulated work to appropriately licensed partners.

受监管固定通信布线必须由具备相应注册的布线技师施工或直接监督。在 NSW，销售、安装、维护或维修 CCTV 等安全设备通常还需要相应安全行业牌照。我们会把普通网络工作与受监管工作分开，并将后者安排给合规合作方。
