We do a lot of this type of work, so diagnosis and spares are well covered
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 eco-agriculture firms client working in Chenjia Town 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.
A guesthouses and resorts client in Xinhe 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.
What you most want to know about on-site service in Xinhai
Not necessarily. We diagnose first and repair where possible — many blue-screen, slowdown and boot issues are fixable, and we only suggest reinstall when repair won't do.
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.
