Pinpoint the real fault on site
Business, store and home clients alike, with a technician arranged nearby
The client moved into a new office in Sijing, 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.
What you most want to know about on-site service in Yongfeng
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.
