1 Network Education (网络科普)

Plain-language explainers so customers understand what they're paying for before we even visit.

用大白话讲清楚,让客户在我们上门之前就明白自己到底在为什么付费。

Educational Guide科普讲解

What actually is NBN, and why does my building have OptiComm instead?

NBN到底是什么?为什么我这栋楼用的是OptiComm?

NBN is the government-funded national network; retailers like Telstra, Optus and TPG just resell access to it. Many newer apartment blocks instead run on OptiComm, a private fibre network with its own pricing, completely separate from NBN. Understanding this distinction upfront saves new arrivals real money and confusion.

NBN是政府出资建设的国家宽带网络,Telstra、Optus、TPG这些零售商只是转售接入权。很多新建公寓楼走的却是OptiComm——一个完全独立于NBN、有自己定价体系的私有光纤网络。刚到埠时先搞清楚这个区别,能省下不少钱和困惑。

2 New Installation (网络安装)

Getting a brand-new connection live, tested, and actually fast — same day where possible.

把全新连接开通、测试到位、真正跑起来——能当天搞定就当天搞定。

Waterloo · Same-Day SetupWaterloo · 当天完成安装

NBN activated in the morning, installed by the afternoon

上午开通,下午就装好

A UNSW postgraduate near Waterloo (Sam Sing Street) needed internet fast. After a quick needs assessment — household size, devices, gaming/streaming habits — we submitted a 500Mbps Superloop plan and had it installed and speed-tested the same day.

一位在Waterloo(Sam Sing Street附近)的UNSW研究生急需用网。简单了解家庭人数、设备情况、游戏/追剧习惯后,我们提交了500Mbps的Superloop套餐,当天完成安装和测速。

3 Network Optimisation (网络优化)

Making an already-working connection actually reach every room.

让已经能用的连接真正覆盖到每一个房间。

Randwick · 2-Storey HouseRandwick · 两层House

World Cup on the 2nd floor, down to 3–4Mbps

二楼看世界杯,网速只剩3–4Mbps

A 50Mbps Telstra NBN line, a 10+ year old WiFi-4 repeater, and a strict no-visible-cabling rule (a wheelchair-using family member). We retired the old repeater and deployed a wired-backhaul TP-Link Deco X50 mesh — zero new visible cabling, full-strength WiFi upstairs in time for kickoff.

50Mbps的Telstra NBN线路,一台用了十年以上的WiFi-4中继器,还有严格的“不能有明线”规定(家里有轮椅使用的家庭成员)。我们淘汰了老中继器,部署了有线回程的TP-Link Deco X50 mesh——没有新增任何明线,赶在开球前二楼恢复满血WiFi。

5GHz WiFi unusable through several walls

隔几堵墙,5GHz WiFi完全用不了

5GHz carries more data but travels a much shorter distance through obstacles than 2.4GHz. We explained the trade-off and reconfigured the setup — splitting bands and repositioning the router — for reliable coverage in that specific room.

5GHz传输数据量更大,但穿墙能力比2.4GHz弱很多。我们跟客户解释清楚这个取舍关系,重新做了分频段和路由器摆位调整,让那个特定房间也能稳定覆盖。

4 Troubleshooting (故障排查)

When something that used to work suddenly doesn't, or never worked as advertised.

曾经能用的东西突然不能用了,或者从一开始就没达到宣传的效果。

Zetland · UNSW ApartmentZetland · UNSW学生公寓

450Mbps plan capped around 200Mbps, unstable connection

450Mbps套餐被限制在约200Mbps,连接还不稳定

A UNSW student apartment in Zetland was contracted for a 450Mbps NBN plan but WiFi speed was capped around 200Mbps with an unstable connection. The cause: the wall-mounted UniFi access point had its Ethernet port disabled by the building's own network configuration, blocking a wired connection entirely. We diagnosed it on-site, bypassed the restricted building AP configuration, then supplied and installed a dedicated router with a wired Ethernet run to the PC — restoring a stable 450Mbps+ wired connection at the full contracted speed.

悉尼Zetland某UNSW学生公寓,NBN合同带宽450Mbps,但WiFi实测速度仅约200Mbps,信号还不稳定。原因:墙面UniFi接入点的网口被公寓自身的网络配置禁用,导致完全无法接入有线网络。我们现场排查故障,绕过受限的AP配置,部署了专用路由器并完成有线网络布线至电脑——最终实现450Mbps+的稳定有线连接,达到合同全额带宽。

100Mbps plan, testing 20Mbps for over a month

100Mbps套餐,测速却只有20Mbps,持续一个多月

A Grandstand Parade apartment in Zetland had a 100Mbps Superloop/OptiComm FTTB plan testing at only 20Mbps from day one. We traced it to the ISP's incomplete technical provisioning and pushed for a fix until the connection reached full plan speed.

Zetland Grandstand Parade一套公寓,100Mbps的Superloop/OptiComm FTTB套餐从第一天起就只能测到20Mbps。我们追查到是运营商侧的技术开通没做完整,持续跟进直到网速恢复到套餐应有水平。

Mascot · Airport InterferenceMascot · 机场信号干扰

New router works fine, a different one drops out constantly

一台路由器好好的,换了另一台却天天掉线

A Mascot household's WiFi worked perfectly on a Xiaomi router, but switched to nightly dropouts the moment they installed an imported high-end gaming router. The router's advanced radar-detection features were unusually sensitive to signals near the airport flight path — an unusual, hard-to-diagnose fault we traced through elimination.

Mascot一户人家用小米路由器时WiFi完全正常,换成进口高端游戏路由器后却每晚掉线。这台路由器的雷达检测功能对机场航线附近的信号异常敏感——一个不常见、很难诊断的故障,我们通过排除法追查出来。

5 Computer Repair (电脑维修)

From student laptops to serious hardware — diagnosed honestly, fixed properly.

从学生笔记本到高配主机——诚实诊断,认真修好。

AU$3,800 ASUS ROG router throwing DHCP errors

3,800澳元的ASUS ROG路由器一直报DHCP错误

A friend's high-end ASUS ROG GT6 AX10000 gaming router kept failing to get an IP address on a freshly activated Superloop 1000Mbps line. After ruling out an ISP-side fault (a loaner TP-Link connected instantly), a full reset and reconfiguration got it back online — wired speeds hit full gigabit, WiFi held 900Mbps+ throughout the apartment.

朋友一台高端ASUS ROG GT6 AX10000游戏路由器,在刚开通的Superloop千兆线路上一直拿不到IP地址。先排除运营商侧故障(借一台TP-Link一插就通),再完整重置重新配置后恢复上线——有线跑满千兆,WiFi全屋稳定在900Mbps以上。

Two high-end gaming PCs, one stack-based buffer overflow

两台高配游戏主机,一次栈缓冲区溢出

A desktop worth roughly AU$20,000 (RTX 4090, Ryzen 9, dual monitors) suddenly lost internet access, with volume, brightness and Bluetooth controls all greyed out. Diagnosis traced it to a ShellHost.exe stack-based buffer overflow — cleaned and restored over a five-hour session without wiping the customer's data.

一台价值约2万澳元的台式机(RTX 4090、Ryzen 9、双显示器)突然断网,音量、亮度、蓝牙控制全部变灰不可用。诊断追查到是ShellHost.exe的栈缓冲区溢出——耗时五小时清理修复,全程没有清空客户的数据。

6 Data Recovery (数据恢复)

Data first, reinstalling second — always in that order.

永远先保数据,再考虑重装——顺序不能反。

Desktop PC stuck in a blue-screen loop, thesis data intact

台式机反复蓝屏死机,论文数据完好保住

A USYD postgraduate's desktop was stuck in a blue-screen reboot loop with important research data on the drive. We backed up everything first, then rebuilt the system cleanly. As a bonus, we noticed the room was only getting 20Mbps on a much faster plan — optimised on the spot to 90Mbps+.

一位USYD研究生的台式机陷入蓝屏重启死循环,硬盘里有重要的研究数据。我们先把所有数据备份好,再干净地重建系统。顺带发现这个房间在更快的套餐下只跑20Mbps,当场优化到90Mbps以上。
