From a single device to a whole office, all handled the same way

A startup teams client in Yangpu Riverside had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.

The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.

The client moved into a new office in Yangpu Riverside, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
What you most want to know about on-site service in Wujiaochang
Yes, billed monthly by machine count, including upkeep and emergency repairs.
AP deployment is RMB 150–400/AP, whole-home plans from RMB 800, depending on area, floors and whether cabling is needed. Survey is free — we give a point map and budget first.
As fast as 30 minutes if close and traffic is light, most jobs scheduled the same day. Survey and plans are free.
It depends. Existing network ports can be used directly; otherwise we run surface trunking or ceiling runs, kept as concealed as possible.
Not necessarily. A single router can't punch through many walls regardless of power; dead zones are usually solved by point distribution, and we'll explain during the survey.
We walk-test speeds in every room, check signal strength and handoff, and finish only when it meets the bar.
Describe the device and the symptoms; our technician brings the right tools and common parts. Diagnose first, quote after, and repair only once you approve.
