A bank branches client in East Nanjing Road 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 East Nanjing Road, 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.

A office-tower firms client working in Yu Garden had devices failing and holding up progress. We visited by appointment and handled them in groups, restoring normal use the same day and logging the devices into a table.

Most cases just need one access device on the existing network; we assess first.
No — accounts are revoked the same day per process, with auditable access records.
Yes. Read-only or read-write permissions by role.
Yes — add accounts and assign permissions per the process.
Most of the time, yes. Ordinary broadband doesn't allow outside access to the intranet by default, and exposing ports directly is risky. The solution uses an encrypted tunnel to safely open the intranet to designated people.
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.
