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

The client moved into a new office in Nanxiang, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.

The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.

The client needed to operate normally during the day, so we came after hours. Several staff worked in parallel and finished testing and cleanup before closing.

Windows, Mac, phones and tablets. Desktops and laptops just need the client installed; staff can check approvals and documents on their phones too.
No. On-site work starts by looking at the existing structure and bandwidth, and we schedule the switch after hours or on weekends, testing each part before handover.
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.
