Connected but no internet? Speeds a fraction of what you pay for? Random nightly drop-outs? These all look the same to you but have very different causes. We isolate exactly where the fault is — the ISP line, the modem, the router or a single device — and fix it.
显示已连接却没网？网速只有套餐的零头？每晚随机掉线？在你看来都一样，其实原因大不相同。我们精准定位故障到底在哪 — 运营商线路、光猫、路由器还是某一台设备 — 然后修好它。
The classic case where WiFi shows connected but nothing loads — usually DNS, a lease/IP issue or an upstream line fault. We find which.
经典问题：WiFi 显示已连接却打不开网页 — 通常是 DNS、IP 租约问题或上游线路故障。我们判断是哪一种。
When you pay for 100/250/1000Mbps but get a fraction, we benchmark the line and pinpoint the bottleneck — line, hardware or WiFi.
当你买了 100/250/1000Mbps 却只跑到零头，我们测线路、定位瓶颈 — 线路、硬件还是 WiFi。
Drop-outs at the same time each night, or under load, point to congestion, a failing modem or a line-sync fault — we log and confirm it.
每晚固定时间或负载高时掉线，指向拥堵、光猫老化或线路同步故障 — 我们记录并确认。
When only one laptop or TV struggles while everything else is fine, the fault is the device or its adapter — not your whole network.
当只有某台笔记本或电视有问题、其他都正常时，故障在设备或其网卡 — 不是整个网络。
Describe the symptom and when it happens — all the time, at night, only on one device.
描述症状和发生时间 — 一直如此、晚上、还是只有一台设备。
On-site we test methodically: line sync, wired speed, WiFi speed, then per-device, to isolate the layer that's failing.
上门后我们按层次测试：线路同步、有线网速、WiFi 网速，再到每台设备，隔离出出问题的环节。
We fix what we can on the spot — settings, hardware, cabling — and call the ISP if the fault is upstream.
能当场修的就修 — 设置、硬件、布线 — 如果问题在上游就代你联系运营商。
You get a clear explanation of the root cause, not just a temporary reset.
你会得到清晰的根因解释，而不只是临时重启一下。
Diagnostic visits start at $150 and include the fix where it's something we can resolve on-site. If the root cause turns out to be an ISP or NBN line fault we can't fix, we still give you the documented evidence to force your provider to act — that alone often ends months of finger-pointing.
诊断上门从 $150 起，能当场解决的情况已含修复。如果根因是我们无法修复的运营商或 NBN 线路故障，我们仍会给你书面证据去推动运营商处理 — 光这一点往往就能结束几个月的互相推诿。
High ping traced through the line and router to a specific congestion source, then resolved.
高延迟从线路、路由器逐层排查到具体拥堵源，随后解决。
